Seattle Mariners vs Baltimore Orioles Prediction

Rogers has been fantastic this season, and that includes 24 hits and five runs allowed in his last 40.1 innings. However, Rogers pitches for the Orioles, and it’s hard to take them seriously regardless of who is on the mound. The Mariners are rolling and Gilbert has found his form this season with a 3.35 ERA and 0.98 WHIP. Gilbert has allowed 27 hits and 13 earned runs in his last 37.2 innings. The Mariners are too hot to bet against, especially for a bad team such as the O’s. Give me the road team.
