A’s at Mariners picks and predictions
Prediction
Mariners 5, A’s 4
Moneyline
LEAN MARINERS (-154).
The Mariners have played well at home recently, beating the Braves in 2 of 3 and the Diamondbacks in 2 of 3 in their last homestand. They swept the Reds in 3 in the home series prior.
The A’s, after snapping a 6-game winning streak in early May, have lost 4 of their last 5 games. They have allowed at least 4 runs in Blackburn’s last 3 starts. For a small unit, take MARINERS (-154).
Run line/Against the spread
PASS.
The Mariners -1.5 (+140) are too risky as a run-line favorites. As mentioned, they’re 9-10 ATS at home and 18-20 ATS overall.
The A’s +1.5 (-170) are too expensive to take as underdogs, especially having struggled to cover as of late.
Over/Under
BET OVER 7.5 (-105).
The A’s have gone Over in Blackburn’s last 2 starts and have topped the projected total in 3 straight games and in 5 of their last 6. Oakland has scored at least 8 runs in 3 straight games as well.
The Mariners might be 11-25-2 O/U on the season but have gone Over in 3 straight games, allowing at least 6 runs in each of those contests. Woo could have some rust as well, making his 1st start of the season.
Seattle has scored 14 runs over its last 3 Games, so its offense has been solid as well.
Back OVER 7.5 (-105).
