Los Angeles Angels vs Seattle Mariners Preview
The Los Angeles Angels enter Monday at 36-49 after taking two of three games from the Athletics. The Angels won the final two games of the series by scores of 5-2 and 4-1.
Josh Lowe supplied all four Los Angeles runs Sunday with his first career grand slam. Sam Aldegheri limited the Athletics to one run over five innings before José Fermin, Ryan Zeferjahn, and Samuel Natera completed the victory.

The Angels have now won seven of their last nine games, including series victories over Baltimore and the Athletics. That recent form makes them more dangerous than their fifth-place record initially suggests.
Los Angeles has also produced better season-long offensive numbers than Seattle. The Angels are batting .240 with a .318 on-base percentage and .398 slugging percentage while averaging approximately 4.5 runs per game.
Seattle is batting .232 with a .313 on-base percentage and .382 slugging percentage. The Mariners have scored 44 fewer runs despite playing the same number of games.
The Angels have also hit 100 home runs. Their active lineup still contains several players capable of attacking Kirby even without Mike Trout.
Zach Neto has become the primary power threat near the top of the order. He enters with 17 home runs, 16 doubles, two triples, and a .441 slugging percentage.
Neto’s batting average remains below his established standard, but his combination of patience and extra-base power forces pitchers to work carefully. He can punish fastballs left near the centre of the strike zone.
Kirby’s command usually prevents extended walk-driven rallies, so Neto may need to create damage through early-count contact rather than waiting for several favourable pitches.
Jo Adell has been Los Angeles’s most consistent hitter during the last several weeks. He is batting .300 with a .356 on-base percentage and .488 slugging percentage over his last 19 games.
Adell has also recorded seven doubles, two home runs, and 10 RBIs during that stretch. His recent contact improvement is important against a pitcher who generally attacks the strike zone.
Kirby rarely gives hitters free bases. Adell must be prepared to hit a quality strike rather than expecting the count to move automatically in his favour.
Nolan Schanuel enters batting .262 with a .335 on-base percentage. He provides a left-handed contact bat capable of forcing Kirby to work through longer plate appearances.
Schanuel homered during Johnson’s victory over Baltimore and continues to give the Angels a dependable on-base option near the top of the lineup.
Lowe gives Los Angeles another left-handed threat. His grand slam Sunday provided the clearest sign that his power may be beginning to emerge after an inconsistent start with the Angels.
Logan O’Hoppe, Jorge Soler, Oswald Peraza, Christian Moore, Donovan Walton, Wade Meckler, and the available depth hitters complete the likely lineup.
Walton has quietly supplied consistent contact. Peraza offers more speed and occasional pull power, while Soler remains capable of changing a game with one mistake over the plate.
The Angels remain without Trout because of a hamstring injury. The veteran outfielder leads the team with 17 home runs despite missing significant time.
Adam Frazier is also on the injured list with an elbow problem. Gustavo Campero and Grayson Rodriguez are unavailable as well.
The injury list reduces Los Angeles’s depth, but the original draft overstates the extent of the problem by relying on players who are no longer central to the active roster.
The larger concern is the pitching staff. Los Angeles carries a 4.59 team ERA and 1.40 WHIP.
Angels pitchers have issued 383 walks, one of the highest totals in baseball. The staff has also struggled to prevent multi-run innings when starters leave with runners on base.
The bullpen worked four innings Sunday. Natera threw 24 pitches to complete the ninth, while Zeferjahn had command problems during his appearance.
Kirby Yates did not handle the final inning, which could leave Los Angeles with an experienced high-leverage option Monday. The bullpen as a whole remains substantially less dependable than Seattle’s pitching staff.
The Seattle Mariners enter Monday at 42-43 after losing 6-5 to Cleveland on Sunday. The defeat completed a 2-4 road trip through Pittsburgh and Cleveland.
Seattle carried a 4-1 advantage into the eighth inning before Michael Rucker and Josh Simpson allowed five runs.
The collapse continued a frustrating stretch for the Mariners. Seattle had gone 13 consecutive games without scoring more than three runs before finally reaching five Sunday.
That streak tied a franchise record and helps explain why laying more than -200 on the moneyline is uncomfortable despite the pitching mismatch.
Seattle left 14 runners on base Sunday. The Mariners created traffic but repeatedly failed to produce the hit needed to separate from Cleveland.
Julio RodrĂguez has been one of the few hitters moving in the right direction. He enters with a five-game hitting streak and is batting above .380 during that span.
RodrĂguez leads Seattle with a .423 slugging percentage and has produced 14 home runs, 15 doubles, 11 stolen bases, and 40 RBIs.
The overall numbers remain below his superstar expectations, but his recent contact is encouraging. Johnson has allowed 24 hits and five home runs in only 19.1 innings, creating a favourable opportunity for RodrĂguez.
Randy Arozarena recently returned from a hamstring injury. He enters batting .283 with a .370 on-base percentage and .442 slugging percentage.
Arozarena leads Seattle in hits and has added seven home runs, 33 RBIs, and 19 stolen bases. His return gives the Mariners another patient hitter capable of taking advantage of Johnson’s command problems.
Arozarena can create runs without recording an extra-base hit. A walk, single, or hit-by-pitch can quickly become a scoring opportunity because of his baserunning.
Josh Naylor supplies another experienced middle-order bat. He enters with 79 hits and should receive the platoon advantage against Johnson.
Naylor has not produced his strongest power season, but his contact ability makes him difficult to retire when pitchers fall behind.
Cal Raleigh has endured a disappointing offensive season after his historic 2025 power performance. He is batting below .170 with eight home runs.
Raleigh still possesses considerable pull power. Johnson’s five home runs allowed and 1.71 WHIP give the Seattle catcher a favourable matchup despite his poor recent trends.
J.P. Crawford has returned to the active lineup and provides additional patience near the top. Cole Young, Colt Emerson, VĂctor Robles, Mitch Garver, Rob Refsnyder, and the available depth hitters complete the likely order.
Robles produced two hits and three stolen bases Sunday. His speed can create immediate pressure whenever Johnson allows a baserunner.
Seattle is managing several position-player injuries. Dominic Canzone is day-to-day with right hamstring soreness after aggravating the injury while running out a double.
Luke Raley is day-to-day with elbow soreness sustained during a swing. Brendan Donovan remains on the injured list with a groin strain.
Those absences help explain Seattle’s recent scoring problems. The Mariners have been forced to use several different lineups while waiting for their established hitters to return.
The pitching staff remains Seattle’s primary advantage. The Mariners own a 3.72 team ERA and 1.19 WHIP.
Seattle pitchers have issued only 216 walks, dramatically fewer than the Angels. That command advantage reduces the number of free scoring opportunities Los Angeles receives.
The bullpen struggled Sunday, but the collapse was concentrated around Rucker and Simpson rather than Seattle’s entire relief group.
Kirby’s ability to work six innings would allow the Mariners to avoid asking the same relievers to protect another narrow lead.
Pitching Matchup
The Angels will start right-hander Ryan Johnson, who enters at 1-2 with an 8.84 ERA, 1.71 WHIP, and 15 strikeouts across 19.1 innings.
Johnson has made six major-league appearances, including three starts. His overall results remain poor, but his latest performance completely changed the immediate outlook.
The rookie held Baltimore scoreless over six innings last Tuesday, allowing one hit and striking out a career-high eight.
Johnson carried a no-hitter into the sixth inning and allowed only one single. He entered the start with an ERA above 12.00 before lowering it to 8.84.
The performance demonstrated genuine swing-and-miss ability. Johnson attacked Baltimore with greater confidence and located his secondary pitches below the strike zone.
The question is whether that outing represents a sustainable adjustment or a single outlier against an inconsistent Orioles lineup.
Johnson allowed 23 hits, 19 earned runs, nine walks, and five home runs across his other 13.1 innings.
His 6.36 fielding-independent pitching mark indicates that the poor season-long results were not entirely caused by defensive mistakes or unusual sequencing.
Johnson’s command is the central problem. Nine walks in 19.1 innings create too much traffic, particularly against hitters such as Arozarena, Crawford, Naylor, and RodrĂguez.
Seattle has struggled to convert baserunners, but Johnson can create scoring opportunities without requiring the Mariners to produce several hits.
The rookie’s home-run rate presents another concern. T-Mobile Park suppresses offense compared with many venues, but RodrĂguez, Raleigh, Arozarena, Naylor, and Garver can still punish elevated fastballs.
Johnson will also be making his first start at T-Mobile Park. The environment should help him, but Seattle’s lineup can force him to throw more pitches than Baltimore did.
Los Angeles allowed Johnson to throw six innings and 91 pitches during his latest start. A similar workload is possible if he maintains his command.
Another six-inning performance would provide the Angels with a realistic chance to cover the run line. A return to his earlier form would force Los Angeles into its bullpen by the fourth or fifth inning.
The Mariners counter with right-hander George Kirby, who enters at 6-7 with a 3.94 ERA, 1.34 WHIP, and 84 strikeouts across 96 innings.
Kirby has allowed 106 hits, which is unusually high for a pitcher known for limiting walks. His strike-throwing approach has occasionally produced too much contact inside the zone.
The right-hander has issued only 23 walks. That elite control prevents several of the hits from becoming multi-run rallies.
Kirby completed six innings in each of his last three starts. He allowed one earned run against Pittsburgh, then three in consecutive appearances against Baltimore.
He recorded five strikeouts against Pittsburgh, five in his first Baltimore start, and 10 during the rematch.
Kirby therefore enters with 20 strikeouts over his last 18 innings. The recent swing-and-miss production is stronger than his full-season average.
His career history against the Angels is also encouraging. Kirby owns a 7-4 record with a 3.41 ERA and 85 strikeouts across 11 appearances against Los Angeles.
The current Angels lineup contains several hitters who have struggled with his combination of velocity and command.
O’Hoppe has struck out frequently in the matchup, while Neto has had difficulty producing hits. Adell has experienced more success but has also accumulated strikeouts.
The Angels’ active lineup can still create contact. Schanuel, Walton, Peraza, Lowe, and Moore give Los Angeles enough different approaches to prevent Kirby from simply overpowering everyone.
Kirby’s 1.34 WHIP also means the Angels should receive some baserunners. The challenge will be producing extra-base damage before Seattle’s defense or bullpen ends the inning.
Los Angeles has struck out 746 times, creating a favourable opportunity for Kirby to exceed his 6.5-strikeout prop.
He may need seven full innings to reach that number if the Angels continue making contact early in counts. His recent workload and Seattle’s bullpen needs make an extended outing realistic.
Game Thesis: Seattle owns a major advantage in the confirmed starting-pitching matchup, team ERA, command, bullpen depth, and home environment. The Angels have the stronger season-long offense and enter with much better recent form, preventing the Mariners from becoming an automatic play at more than -200. Johnson’s dominant start against Baltimore provides legitimate uncertainty, but his full-season command, home-run, and baserunner numbers remain alarming. Kirby should control the Trout-less Angels lineup while Seattle creates enough scoring opportunities against Johnson and the Los Angeles bullpen. A projected 5-2 Mariners victory makes Seattle -1.5 the best bet, Seattle the moneyline selection, and Under 8 the preferred total.
Best Bet - Spread Pick: Seattle Mariners -1.5 (+105)
Seattle -1.5 is the strongest wager because it provides a plus-money alternative to an expensive moneyline.
The starting-pitching gap is significant. Kirby owns a 3.94 ERA and has completed six innings in three consecutive starts, while Johnson carries an 8.84 ERA and 1.71 WHIP.
Johnson’s latest start deserves respect, but one dominant outing does not erase the 19 earned runs he allowed across his other 13.1 innings.
Seattle’s offense has been poor for most of June. The Mariners went 13 straight games without scoring more than three runs and lost four of six on their road trip.
That offensive slump is the primary risk attached to the run line. Seattle can pitch well and still win only 3-2 or 2-1.
The matchup provides an opportunity for the lineup to break through. RodrĂguez is on a five-game hitting streak, Arozarena has returned, and Johnson has allowed five home runs in fewer than 20 innings.
Los Angeles also owns a 4.59 team ERA and 1.40 WHIP. The Mariners should receive opportunities after Johnson leaves even if the rookie delivers another competitive start.
The current +105 return is preferable to laying approximately -205 on Seattle simply to win.
Total Pick: Under 8 (-120)
The total opened near eight runs before moving primarily to 7.5. That adjustment reflects the pitcher-friendly venue, Seattle’s offensive slump, and Kirby’s matchup advantage.
Kirby should limit a Los Angeles lineup missing Trout. The Angels may create several hits, but his command makes large innings less likely.
Seattle’s offense has scored three runs or fewer in 13 of its last 14 games. The Mariners finally reached five Sunday but still struggled with runners in scoring position.
Johnson is the primary threat to the Under. His full-season numbers create a realistic path for Seattle to score five or six runs.
The rookie’s six scoreless innings against Baltimore also show that he is capable of providing more resistance than the ERA suggests.
Taking Under 8 rather than Under 7.5 is important. A 5-3 or 4-4 game produces a push instead of a loss.
The selected total also aligns with Seattle winning by multiple runs. A 5-2 or 4-1 result cashes both the spread and Under.
Top Player Prop Picks for Angels vs Mariners
George Kirby Over 6.5 Strikeouts (-104, bet365): Kirby has recorded 20 strikeouts over his last 18 innings, including a 10-strikeout performance against Baltimore. He also owns 85 career strikeouts across 11 appearances against the Angels. Los Angeles has accumulated 746 strikeouts this season and is missing Trout, one of its most disciplined hitters. Kirby has completed six innings in three straight starts and may receive an extended workload after Seattle’s bullpen collapse Sunday. Seven strikeouts represents an aggressive but reachable number at close to even money.
Julio RodrĂguez Over 1.5 Total Bases (+120, BetMGM): RodrĂguez enters with a five-game hitting streak and is batting above .380 during that span. He leads Seattle with a .423 slugging percentage and should bat near the top of the order against Johnson. The Angels starter has allowed 24 hits and five home runs in 19.1 innings, giving RodrĂguez several paths to clear the line with one extra-base hit or two singles. His speed also turns borderline contact into additional bases. The plus-money return is preferable to laying more than -200 on a basic hit prop.
Randy Arozarena Over 1.5 Total Bases (+182, bet365): Arozarena is batting .283 with a .370 on-base percentage and .442 slugging percentage after returning from a hamstring injury. He should receive multiple plate appearances against Johnson and an Angels bullpen carrying a 4.59 staff ERA. Arozarena can clear this prop with one double, triple, or home run, while his strong contact and plate discipline create a second path through two singles. The unusually high +182 price compensates for Seattle’s recent offensive problems and Arozarena’s short return from the injured list.
