The Blue Jays' rotation has been inconsistent this season, with more struggles in the second half. Kevin Gausman, Shane Bieber, and Trey Yesavage may have secured postseason rotation spots, while Max Scherzer may have pitched himself out. Gausman has excelled recently, with eight quality starts in 11 outings, a 2.19 ERA, and a 73:13 strikeout-to-walk ratio, proving he will be the postseason ace.
Shane Bieber returned strongly from 2024 Tommy John surgery. In four of six starts, he's thrown at least 5 1/3 innings, allowing two or fewer earned runs, with a 34:5 strikeout-to-walk ratio, likely securing the No.
