Houston Astros vs Seattle Mariners Prediction

The Mariners should be favored at home with Gilbert on the mound, but he’s also allowed 17 hits and 12 runs in 17.2 innings this month. The Mariners have been one of the biggest underachievers in baseball and aren’t a team I’m thrilled to lay juice with. The Astros are in the thick of a division race, and while Javier has been a mess this season, he’s been sharper lately, allowing 9 hits and 4 runs in his last 16.1 frames. I like getting teams with something on the line at more favorable prices this time of year. Give me the Astros.
