What happened: The Red Sox have appointed left-handed pitcher Alec Gamboa as the club's 27th man. The roster move provides an extra arm for the second game of Wednesday's doubleheader against BAL.

Why it matters: Adding a 27th man is a standard procedure during doubleheaders to help manage pitching workloads. The transaction gives the bullpen needed depth to navigate the remaining innings of the twin bill.

What to watch: Gamboa is available out of the bullpen for the nightcap.
