Season series: Tied 1-1
The A’s are coming off an 8-1 win as +209 underdogs vs. the Mariners Saturday with the Over (8) hitting. CF JJ Bleday hit a 2-run HR in the 9th inning, and rookie RHP Joey Estes earned his 1st MLB win.

A’s at Mariners picks and predictions
Prediction
Mariners 6, A’s 3
Moneyline
Seattle (-250) is favored by -200 or more for a 2nd straight game. The Mariners were blown out Saturday, but it’s unlikely that the market would be this wrong about them in back-to-back games. However, I can’t recommend risking $250 to win $100 on the ML.
PASS. Bet the run line and/or total instead.
Run line/Against the spread
Seattle has struggled to score runs recently, but it should they should get to the lefty early. Wood has allowed 4 or more earned runs in 3 of his 8 starts and has only pitched more than 5 innings twice all season. The Mariners have a good shot at returning the favor Sunday after getting routed as -232 home favorites.
BET MARINERS -1.5 (-110).
Over/Under
The Over has hit in 5 straight Mariners games, and that’s where we’re leaning with this pitching matchup. However, while Oakland has scored 8 or more runs in 4 of its last 5 games, it may come down to Earth against Castillo, who has allowed 2 or fewer earned runs in 5 straight starts.
LEAN OVER 7.5 (-105).
