What happened: Gasper's September 9 start was his first at catcher since June 22, according to [Yahoo Sports](https://sports.yahoo.com/articles/red-sox-lineup-no-adley-191426712.html). Adley Rutschman has appeared in 19 games for Boston, including four of the team's past 10.

Why it matters: If Rutschman handles the primary catching duties in October, Gasper could give Boston a hitting option who also provides emergency coverage behind the plate. That would put Connor Wong's place under pressure, though the choice remains a projection.

What to watch: Watch whether Boston gives Gasper additional catching assignments before the regular season ends. The eventual balance between pitchers and position players will determine how much bench flexibility the club can retain.
