What happened: Tarik Skubal will face his former club for the first time since the Aug. 2 trade. The two-time reigning AL Cy Young winner returns to the organization that drafted him in 2018.
Why it matters: The series opener provides an immediate test of the deadline's biggest pitching move. Skubal enters after three starts with his new club.
By the numbers: Skubal is 8-7 with a 2.91 ERA over 120 2/3 innings this season. He recorded 19 strikeouts and six walks across 17 innings in his first three post-trade starts.
What to watch: First pitch is scheduled for 6:40 p.m. ET. His reception and early command will shape the return.
