The Red Sox activated Bello (personal) from the paternity list Monday, Jen McCaffrey of The Athletic reports.
Bello was away from the club over the weekend while welcoming a new child to the family, but he is back with the Red Sox to start Monday's game against the Rangers. The right-hander sports a nifty 45:12 K:BB over 40.1 innings since the start of July, although he's submitted a 4.46 ERA during that stretch.
