White Sox righty Zach Putnam has undergone Tommy John surgery, Dan Hayes of CSN Chicago was among those to tweet. He’s expected to miss at least one year recovering from the procedure.
Putnam, who’ll soon turn 30, was off to a very strong start to the current season before his elbow flared off. Through 8 2/3 innings, he had allowed just one earned run on two hits while recording nine strikeouts against just one walk.
That showing came on the heels of a strong 2016 — at least when he wasn’t dealing with elbow troubles.
