Anthony DiComo of MLB.com reports that right-hander Chris Flexen, who was scratched from a Grapefruit League start last month due to a sore right knee, underwent surgery to remove a bone chip from the knee. He is expected to miss two to three weeks, making it unlikely he starts the season on time.
Flexen, 22, went posted a 3.56 ERA and 1.313 WHIP over 25 starts last season for Advanced-A St. Lucie. The Mets added him to their 40-man roster last November to protect him from the Rule 5 Draft.
Almost two years removed from Tommy John surgery, Flexen was sitting in the 94-96 MPH range last year and was able to ramp it up to 98 a few times. Coupled with a solid curveball and a developing changeup, the Mets have high expectations for Flexen. He is expected to open the season at Double-A Binghamton.
