Red Sox manager Bobby Valentine said Thursday that Daisuke Matsuzaka (elbow) could be mapped out for a June 1 return.
Matsuzaka, who is working his way back from Tommy John surgery, has already progressed to incorporating his secondary pitches during bullpen sessions. It’s not clear when he’ll be ready for game action, but he need to make it through a bunch of minor league rehab starts before a return to the majors is a realistic possibility. The 31-year-old right-hander is entering the final year of his contract with the Red Sox.
