Giants vs. Athletics
BET: Athletics at the moneyline with PointsBet (+110)
📈 3.3% edge on the sportsbooks' odds
There aren't too many pitchers out there who can compete or compare with the Giants' ace Kevin Gausman, but when he takes on Sean Manaea today, he'll have a worthy enough counterpart that might be able to push him and San Francisco all the way.
Manaea's record doesn't look great at 8-8, but due to limited inning starts, looking at the overall team record when he starts (15-8) is a much fairer reflection of just how good the A's are when he's getting them going. This is a great spot for Oakland.

Mariners vs. Astros
BET: Total runs OVER 9 with PointsBet (-110)
📈 51% probability
Houston put Seattle to the sword last night, blasting 12 runs on their own on their way to a comprehensive victory. With two starting pitchers taking to the mound with high ERAs today in Logan Gilbert and Jake Odorizzi, you can count on this one being yet another runfest in H-Town.

Pirates vs. Cardinals
BET: Total runs UNDER 9 with PointsBet (-110)
📈 53% probability
Pittsburgh were able to shake off a five-game losing skid last night by opening up their weekend series with a win against the Cardinals. While we don't know if the Pirates can back it up tonight, they will be helped by the encouraging showing on Dillon Peters who will be taking the mound. In his first game for the season last week, he gave up only one run in four solidly pitched innings. Paired with Happ on the bump for the Cards' and this one looks good to be a low scoring one.
