Mariners vs. Orioles Probable Pitchers
- Mariners: Emerson Hancock (4-2, 2.80 ERA)
- Orioles: Chris Bassitt (4-4, 5.27 ERA)
Emerson Hancock has been stellar this season for Seattle. The right-hander has allowed more than three runs in just one of his dozen starts, and has gone 23 IP with 5 ER in his last four outings.
Chris Bassitt is questionable to start tonight for the Orioles. He is dealing with lower back issues after going just three innings at Fenway Park in his last start.

Mariners vs. Orioles Best MLB Prop Bets
Orioles Best MLB Prop Bet
- Colton Cowser OVER 1.5 Hits + Runs + RBIs (+137)
Colton Cowser is hoping his mini hot streak can continue as the O’s return home. He’s riding a four-game hitting streak and has homered in each of the last two games.
Alternatively, Cowser to get a hit is -128, and him to go OVER 0.5 HRR is -181 as a possible parlay leg.
Mariners vs. Orioles Prediction and Pick
I can’t trust either of these teams right now, so I’m going with the UNDER tonight in Baltimore.
Hancock has been good for Seattle, and I would lean the Mariners’ way if you’re looking for a side.
Bassitt has been okay for Baltimore, if he gets the start, and the M’s bats are cold recently.
Pick: UNDER 9 (-109)
