The Oakland A's will host the Seattle Mariners on Sunday in the three-game series finale. Seattle won the opener on Friday, 10-2, and the A's bounced back with a 4-3 victory in 10-innings on Saturday. Seattle holds an 8-4 edge against Oakland on the season.


Mariners coming off a rare loss in Oakland

The Seattle Mariners ended the first half of the season with a 14-game winning streak, launching themselves into position for a Wild Card berth. Since the break, the Mariners have maintained their position with a 15-12 record after having a four-game winning streak end on Saturday. Seattle is second in the AL West, 10.5 games behind the Astros, and are tied with Toronto for the top spot in the Wild Card race.

The Mariners are 12th with 135 home runs, 17th in OPS, 22nd in runs scored, and 25th in batting average. The pitching staff is seventh with a 3.65 ERA.

Luis Castillo (5-4, 2.73 ERA) will start on Sunday and has been a tremendous trade deadline addition from the Cincinnati Reds. In three starts with Seattle, Castillo is 1-0 with a 2.18 ERA and 24 strikes against six walks in 20.2 innings. More importantly, Seattle is 3-0 in games started by Castillo, with two victories coming against the Yankees.

A's look to make it two straight

The A's trail Houston by 32.5 games in their division and have the worst record in the American League. The A's are just 18-39 at home but snapped their five-game home losing streak on Saturday. Oakland went 2 for 9 with runners in scoring position and scored the winning run in the 10th inning off a misplayed grounded ball with the bases loaded.

The Oakland A's are in the bottom two offensively in runs scored, batting average, and OPS. They are also just 25th with 104 home runs. The Oakland pitching staff is 24th with a 4.31 ERA.

Southpaw JP Sears (4-0, 1.93 ERA) is scheduled to start on Saturday. The 26-year-old rookie began the season with the Yankees and has made nine appearances, four starts, and pitched 32.1 total innings.

Best Bets for this Game

Full-Game Side Bet

Insiders Status:


The A's are one of the worst offensive teams in baseball and should struggle here. Luis Castillo has been pitching like a Cy Young contender since the end of June and goes deep into games. On the other side, JP Sears ERA and WHIP are very impressive, but he is not overpowering. Sears pitches to contact and has a 44.6% hard-hit rate, above the league average of 35.8%. Sears has also not yet thrown more than 76 pitches in a game. The Mariners are 7-1 in their last eight road games against left-handed starters and 22-8 in their previous 30 road games. Seattle is also 12-2 in their last 14 games played in Oakland. I am on the Mariners.

Prediction: Seattle Mariners -1.5 (-110)

Full-Game Total Pick

Insiders Status:


I don't see either offense lighting up the scoreboard Sunday, and the A's may struggle to score at all. Oakland's starter, JP Sears has only allowed eight walks and one home run in 32.1 innings this season. On the other side, Castillo has allowed two earned runs or less in seven of his last nine starts and not allowed more than three runs in any of those nine contests. I expect a low-scoring ball game here, as long as the Oakland bullpen does not implode.

Prediction: Under 6.5
