Rockies hurler Tyler Chatwood will undergo Tommy John surgery on his right elbow, reports Patrick Saunders of the Denver Post. Given the timing of the procedure, and the fact that Chatwood has already had a UCL replacement, it seems likely that he will miss all of next season.
Chatwood, still only 24, had a promising 2013 season, posting a 3.15 ERA in 20 starts with 5.3 K/9 against 3.3 BB/9. He had been expected to play a major role in the Colorado rotation this year. But, like several other members of the staff, Chatwood has instead missed most of the year due to injury.
The injury certainly has ramifications beyond the season for the Rockies. Chatwood is set to qualify for arbitration eligibility for the first time next year, and the club will have to decide whether to commit to him while he rehabs. Of course, returning from a second TJ procedure is generally a longer and riskier undertaking. While Chatwood has been out since April 29, Saunders explains that he had been working to rehab what was diagnosed as a right flexor strain and elbow inflammation.
