The Astros will host the Seattle Mariners in Game Two of a three-game weekend series at Daikin Park in Houston, TX, today. First Pitch for this AL West battle for control of the division pennant is scheduled for 7:10 p.m. EST. The game will be broadcast on MLB TV.
After Friday’s 4-0 win over the Astros, the Mariners slid into first in the AL West. Houston has held the top spot in the division for most of the season but has played inconsistently down the stretch (6-4 in their last ten) while the Mariners have been winning games (9-1 in their last ten). But Houston has the easier road in the final week with three vs. the A’s in Sacramento and three vs. the Angels in LA. The Mariners have a series vs. the Rockies and the Dodgers. The pitching matchup favors the Astros today with Framber Valdez (12-10, 3.59 ERA) taking the mound against George Kirby (9-7, 4.46 ERA). Valdez has struggled this month, posting a 7.88 ERA through three games, but has been solid at home this season (6-3 in 14 starts with a 2.21 ERA and .217 OBA. Kirby has had some issues on the road, posting a 4-4 record in ten starts with a 5.74 ERA and .285 OBA.

Our Seattle Mariners vs Houston Astros Prediction
Both teams certainly need this win. I’d like to give Houston an edge since Valdez has been the better pitcher over the course of the entire season. But his recent struggles can’t be ignored. With only 11% of moneyline tickets on the Astros but 42% of the handle, that tells me the sharps are backing Houston. I can see this game going either way, so I’m going to bet with the sharps.
