The Mariners (86-69) recognize that fact and are reluctant to lean into discussions of magic numbers to clinch the division title. Gilbert is 1-0 with a 2.20 ERA and 20 strikeouts in 16 1/3 innings across three starts this month. He is 5-4 with a 3.48 ERA in 13 career starts against the Astros. Alexander recorded a 2.82 ERA with 22 strikeouts across 22 1/3 innings in those four starts, with the Astros winning each game. If the Astros are to salvage the finale, they'll need to fashion a better approach against Gilbert.
