Flexen (knee) is on the 7-day DL with High-A St. Lucie, MLB.com's Jonathan Mayo reports.
EDGE Analysis
He underwent surgery in early March to remove a bone chip from his right knee, but could return later this month. Last year was his first full season since undergoing Tommy John surgery, and while he should report to St. Lucie when healthy, he logged 134 innings there last year, so he could quickly get promoted to Double-A.
