Rays at Mariners picks and predictions
Prediction
Mariners 4, Rays 3
Moneyline
The MARINERS (+100) are a solid value in Saturday’s game at even-money, as Seattle looks to avenge Friday’s lopsided loss.
The Rays (-120) beat the brakes off of Seattle in the opener, but Kirby has been solid at home this season, posting a 3.19 ERA across 42 1/3 IP. He has had his issues lately on the road, but he can be trusted to pitch the M’s back into the win column in this middle game of the set.
Run line/Against the spread
If you don’t want to trust the MARINERS +1.5 (-175) straight up, they’re not priced out of line if you’d like a little insurance catching the run-and-a-half.
Seattle is 6-2 on the run line as an underdog in the past 8 tries, while winning 5 of those outings outright.

Over/Under
The UNDER 7.5 (-115) is worth a look in Game 2.
The Under is 13-5-1 in the past 19 games on the road for the Rays, while going 11-5-1 in the past 17 away games against a right-handed starting pitcher.
For the Mariners, the Over has dominated lately, but the Under cashed for Kirby last time out, and the total has gone low in 8 of his past 12 outings overall.
