Red Sox manager Alex Cora said Bello (forearm) will throw live batting practice Saturday, Mike Monaco of ESPN reports.
Bello first started feeling soreness in his right forearm back in mid-February, although he's been pain-free for a while. The young right-hander is not expected to be ready in time for Opening Day, but being ready to face hitters means he's making real progress. He should be able to get in a Grapefruit League start or two before spring training ends.
