Seattle Mariners vs Houston Astros team news, injury reports & key players

Seattle Mariners team news

On the Mariners' side, catcher Cal Raleigh is playing like a dark-horse MVP candidate. He boasts a sizzling .259/.376/.634 slash line, has crushed 38 homers, driven in 82, and crossed the plate 65 times—all while swiping 10 bags on 12 attempts.

Logan Evans will toe the rubber for Seattle, and he'll need to find his form quickly. His advanced metrics paint a rough picture, he ranks in the bottom 10% of MLB pitchers in xBA, xERA, whiff rate, and strikeout percentage. If Evans can limit damage early, Seattle has the offensive firepower to make this a high-scoring affair in their favor.

Houston Astros team news

Third baseman Isaac Paredes has been a steady contributor for the Mariners, sporting an impressive .825 OPS to go with 19 home runs, 49 RBIs, and 51 runs scored. While he hasn’t made much noise on the basepaths, his bat has certainly done plenty of talking.

Lance McCullers Jr. takes the mound for the Astros, but he’s had a tough go this season. According to Baseball Savant, he's sitting near the bottom of the league in several key areas: first percentile in chase rate, and bottom five in both hard-hit and barrel percentages. However, his knuckle curve has been a bright spot, opposing hitters are batting just .192 against it, with a matching slugging percentage and 12 punchouts to show for it. The last time McCullers faced Seattle, he lasted 4.1 innings, allowing two runs on five hits while walking three and fanning eight.
