Ottenbreit is on the mend from Tommy John surgery, Jonathan Mayo of MLB.com reports.
He had the procedure early last season after making just two starts for Single-A Clearwater, so Ottenbreit could come back sometime this summer. It will be interesting to see how the projectable 6-foot-4 righty's stuff looks on the other side of the surgery, as he was a strong candidate to add velocity early in his pro career.
