Klein underwent surgery to remove bone chips in his right elbow Wednesday.
Klein spent the final two months of the season on the injured list due to his elbow, and he's now decided to go under the knife to treat the issue. He's expected to be fully recovered by the time spring training begins and may have to compete for a spot in the Dodgers' bullpen after posting a 3.67 ERA and 1.56 WHIP across 41.2 innings.
