What happened: Adley Rutschman traveled with Boston for its current road series after an expected Tuesday activation. The three-time All-Star is listed third in the batting order at catcher.
Why it matters: The deadline acquisition now joins Boston's lineup for the final seven weeks of the regular season. His arrival gives the club a veteran option behind the plate during the stretch run.
By the numbers: Boston enters Tuesday at 64-54. Rutschman is a three-time All-Star.
What to watch: His workload behind the plate will indicate how quickly Boston plans to establish him as its regular catcher.
