The Mariners played a very weird schedule against the Astros this year: of the 19 times they faced their divisional opponent, 12 of those games—63%—came prior to the All-Star Break. Prior to the All-Star Break, the Mariners were 6-6 against the Astros, but it felt like that number could have been 66-6, as the Mariners finally won a series in Houston for the first time since 2018. It was especially satisfying to win that series in June as they’d been swept in Houston to begin the month. Perhaps, some fans wondered, the tide was beginning to turn in the AL West, finally.
