Seattle Mariners vs. Texas Rangers preview
The Mariners and Rangers bring identical 57-52 records into their crucial AL West showdown at T-Mobile Park, where ace pitchers Jacob deGrom and Luis Castillo square off in what promises to be a classic pitching duel.
Seattle enters with momentum on their side, having won eight of their last ten against Texas while playing dominant baseball at home.
The Rangers' league-leading pitching staff (3.22 ERA) faces a significant test against a Mariners lineup that's finding its groove, averaging 4.51 runs per game.
DeGrom, despite his stellar 10-3 record, has shown vulnerability lately, surrendering five runs in his last outing against the Angels and historically struggling at T-Mobile Park.
Castillo has been nearly untouchable at home, posting shutouts in two of his last three starts in Seattle while maintaining a respectable 3.26 ERA in seven career appearances against Texas.
The contrast between Seattle's surging home form and Texas' recent road struggles (losing six of their last eleven) could prove decisive in this pivotal matchup between division rivals.
