Price (elbow) was able to throw 20 pitches off a mound Wednesday, Peter Abraham of The Boston Globe reports.

Price's catcher was standing during the session, so while he likely wasn't throwing with his full repertoire at maximum velocity, it's still a positive development for the lefty, who had previously been limited to throwing off flat ground. It's expected that Price will need to complete multiple bullpen sessions before the Red Sox clear him to throw batting practice. Given the multiple hurdles he still needs to clear in the recovery process, Price is still trending toward a return to the Red Sox at some point in May.
