PITTSBURGH -- Orioles top pitching prospect Dan Klein was diagnosed with a small S.L.A.P. tear in his right labrum (shoulder), and the plan is for him to forgo surgery and begin a rehabilitation program next week.
Klein was examined by renowned orthopedic specialist Dr. Lewis Yocum on Monday, and the thought right now is he will be able to avoid surgery and likely undergo a rehab procession similar to Orioles reliever Jason Berken, who was shut down last season with a similar injury.
Klein will see team orthopedist Dr. John Wilckens on Friday in Baltimore. He is expected to head to the team's spring facility in Sarasota, Fla., shortly after that to lay the groundwork for a rehab plan. There is no timetable on his return, which will be a matter of months, not weeks, given that he hasn't pitched since June 1.
The 22-year-old Klein was a combined 3-1 with a 1.11 ERA between Class A Frederick and Double-A Bowie, allowing 23 hits and six walks while striking out 37 batters in 32 1/3 innings.
A third-round pick out of UCLA in last year's First-Year Player Draft, Klein was officially put on the Minor League disabled list on June 8 with shoulder tendinitis, after experiencing trouble warming up and getting loose prior to that. Klein has a history of injuries, including a shoulder problem at UCLA that required surgery.
