Angels Are Looking To Avoid The Sweep
The Angels dropped their third straight on Saturday, falling 5–3 to the Mariners despite early sparks from Jo Adell and Bryce Teodosio. Adell crushed his 36th homer of the season in the second inning, and Teodosio added an RBI single, but the offense stalled from there—managing just six hits and striking out 13 times against Bryan Woo. Taylor Ward added a solo shot in the ninth, his 30th of the year, but the Angels couldn’t recover from a five-run deficit. Mitch Farris took the loss, allowing five earned runs over four innings, and the team now sits 12 games back in the AL West.

Offensively, Los Angeles continues to lean on Adell, Ward, and Zach Neto, while Mike Trout remains in a prolonged slump—batting just .233 with 21 home runs and a .241 expected average. The Angels have hit 203 homers this season but rank just 18th in runs per game and 27th in team ERA, a combination that’s made consistency elusive. Injuries have also taken a toll, with Neto day-to-day (hand), Adell battling vertigo, and Logan O’Hoppe in concussion protocol. The bottom half of the order has struggled to extend innings, and the team has gone just 2-for-18 with runners in scoring position over the last two games.
Veteran right-hander Kyle Hendricks (7–9, 4.58 ERA) gets the start Sunday, tasked with stopping Seattle’s eight-game win streak. Hendricks has allowed three or fewer earned runs in five of his last seven starts and brings playoff-tested poise to a rotation that’s leaned heavily on youth. He’s held Mariners hitters to a .216 average across 102 career at-bats, including a .143 mark against Jorge Polanco and a .167 clip against J.P. Crawford. If Hendricks can keep the ball down and avoid early damage, the Angels have a path to salvage the series finale.

Mariners Have Won Eight Games In A Row
Seattle extended its win streak to eight games with Saturday’s 5–3 victory, powered by Bryan Woo’s 13-strikeout performance and timely hitting from Jorge Polanco and Josh Naylor. Polanco ripped a two-run double in the first, and J.P. Crawford added a solo homer in the fourth to give Seattle early control. Naylor chipped in with a two-run single in the fifth, and Matt Brash closed it out for his fourth save. The Mariners remain tied with Houston atop the AL West and have now won 7 of their last 10.
The offense continues to surge behind Cal Raleigh (53 HR, 113 RBI), Julio Rodríguez (.267 AVG, 30 HR), and Polanco, who’s 14-for-35 with 8 RBIs over his last 10 games. Seattle ranks 11th in runs per game (4.67) and third in strikeouts, but their power and late-game execution have carried them through tight contests. Defensively, the Mariners were flawless Saturday, turning two double plays and getting a highlight-reel grab from Victor Robles to rob Ward of extra bases.
On Sunday, George Kirby (8–7, 4.56 ERA) gets the start, looking to build on a season where he’s posted a 1.18 WHIP and held opponents to three runs or fewer in four of his last five outings. Kirby has dominated the Angels in two prior starts this year, striking out 14 in June and nine in July. With playoff stakes rising and the bullpen rested, Seattle is well-positioned to close out the series with a sweep and keep pace in the division race.

Los Angeles Angels vs Seattle Mariners Pick
Angels vs Mariners Spread Pick
- Seattle -1.5 (4 Units)
Seattle -1.5 is a strong play heading into Sunday’s finale, with George Kirby on the mound and the Mariners riding an eight-game win streak. Kirby has held opponents to three runs or fewer in four of his last five starts and owns a 1.18 WHIP on the season. He’s already struck out 23 Angels batters across two prior meetings this year and faces a lineup that’s gone just 2-for-18 with runners in scoring position over the last two games. With playoff stakes rising and Seattle tied atop the AL West, expect a focused, front-running effort from a team that’s covered the run line in five of its last seven wins.
The Angels counter with Kyle Hendricks, who’s been serviceable but vulnerable—especially against power-heavy lineups like Seattle’s. The Mariners rank third in MLB in home runs and have gotten consistent production from Julio Rodríguez, Cal Raleigh, and Jorge Polanco, who’s riding an eight-game extra-base hit streak. Seattle’s bullpen has been airtight, and their defense turned two double plays Saturday to snuff out rallies. With Kirby’s efficiency, the lineup’s momentum, and the Angels’ recent struggles, Seattle is well-positioned to win by margin and close out the sweep.

Angels vs Mariners Over/Under Pick
- Under 8 (5 Units)
Under 8 looks well-supported in Sunday’s matchup, with George Kirby and Kyle Hendricks both capable of working deep and limiting damage. Kirby has held opponents to three runs or fewer in four of his last five starts and dominated the Angels in two prior meetings this season. Hendricks, while not overpowering, has allowed three or fewer earned runs in five of his last seven outings and tends to induce soft contact. Seattle’s bullpen has been airtight during its eight-game win streak, and the Angels have scored just six total runs over the last three games. With playoff pressure tightening execution and both starters trending toward efficiency, this profiles as a 4–2 type finish that stays under the number.
