The following report comes from Nick Cafardo of the Boston Globe:
Mulder is looking for a creative contract as he makes his comeback attempt. He may have to agree to a minor league deal first, with incentives if he makes the major league club. Mulder has worked out for the Giants, Padres, Diamondbacks, Angels, and Phillies over two sessions. In the second session, Mulder, who hasn’t pitched in the majors since 2008, improved his velocity from 88 to 92 miles per hour. It’s a long road back, but the fact that Mulder’s shoulder is showing no signs of discomfort could mean he’d be a good back-end option for someone.
The Red Sox have “inquired” about the 36-year-old left-hander, writes the Boston-based Cafardo, but “probably won’t pursue him” much further.
Mulder allowed 96 runs — 91 earned — over his final 106 major league innings. But there is very little risk in a non-guaranteed minor league contract, so look for him to wind up in camp with a team next spring.
