Joba throwing from half mound

Joba Chamberlain tweeted earlier this week that he threw 20 pitches from a half mound and said that he felt great. The next step in his rehab is to talk to Dr. James Andrews on Friday, who performed his Tommy John Surgery, and get clearance to begin throwing from a full mound.

Joba seems to be on track to participate in extended spring training and could join the Yankees in the Bronx by as early as the middle of May. With the way the bullpen is set right now, without significant injuries they may have the luxury of waiting until mid-June so not to worry about rushing him back.

    I heard some pitchers come back from Tommy John surgery with increased velocity. Is that true?

    • Occasionally. It doesn't happen too often though. Some people think that it has to do with the muscles and ligaments being stronger, but it probably has more to do with using their time off productively. A year or so off gives them plenty of time to work on their deliveries and smooth out some mechanics. A slight bump in velocity can come from having slightly better mechanics.

      I know that there was a lot of talk the the year away during Dellin Betances' TJS gave him a lot of time to refine his changeup.
