What happened: Petey Halpin credited outfield teammate Steven Kwan for helping him feel comfortable and answering his questions since his initial call-up. Halpin pointed to Kwan's leadership while sharing the grass in Cleveland.

Why it matters: Chemistry in the outfield carries extra weight during the postseason, with the series between the Tampa Bay Rays and the Cleveland Guardians tied 1-1. Having a settled veteran alongside a younger outfielder stabilizes the defense during high-leverage October innings.

What to watch: The Tampa Bay Rays and the Cleveland Guardians are currently tied 0-0 with their game in progress.
