Houston Astros vs. Seattle Mariners Predictions

The Astros are sending Cristian Javier to the mound, who has been stabilizing at the right time. He has pitched to an ERA of 4.50 in his last 20 innings with a WHIP of only 1.10. In those four games, he owns a tremendous xFIP of 3.48. He has also managed 13.50 K/9 in that small sample, including 11 in five innings last time out versus a strong Baltimore offense. This indicates that Javier is finding the dominant form we saw last year and that he could be a pitcher to buy heading into the postseason.

On the other hand, the Mariners are sending George Kirby to the mound. Kirby has stumbled a little down the stretch and enters this matchup with an ERA of 5.64 across 22 1/3 innings in September. He holds a WHIP of 1.22 in those outings. He has pitched to an xFIP of 4.66 in those four starts, compared to a season-long mark of 3.55. This suggests that Kirby might be struggling to maintain his form, which could be a disadvantage for the Mariners.

When it comes to offense, the Astros have been dominant. Over the last 30 days, the Astros have hit to a wRC+ of 142. That mark paces baseball by a significant margin, and they have displayed an elite process at the plate, striking out only 16% of the time with a BB/K ratio of 0.55. This indicates that the Astros have a strong offensive lineup that could pose a challenge for the Mariners.

On the other hand, the Mariners have hit a wRC+ of 99 over the last 30 days, which ranks 15th in baseball. The Mariners have struck out 25.3% of the time in that sample, which is the fifth-highest mark league-wide. This suggests that the Mariners’ offense might struggle against the Astros’ pitching.

Houston Astros vs. Seattle Mariners Picks

Given the recent form of both teams and the pitching matchup, the Astros seem to have the upper hand in this game. Javier’s recent form suggests that he could be a dominant force on the mound, while Kirby’s recent struggles could pose a problem for the Mariners.

Furthermore, the Astros’ strong offensive lineup could pose a challenge for the Mariners’ pitching. Therefore, the pick for this game is the Houston Astros. They have the momentum, the form, and the statistical edge to come out on top in this crucial matchup.
