MINNEAPOLIS -- The A's injury bug is seemingly doing its best to make its way from the Major League level all the way down to the Minors, where highly regarded pitching prospect Michael Ynoa will shut things down and undergo surgery Aug. 24.
Although the extent of Ynoa's elbow issues won't be known until the time of the procedure, A's assistant general manager David Forst said Friday that the club anticipates ulnar collateral ligament (UCL) reconstruction -- otherwise known as Tommy John surgery, which typically requires more than a year's worth of recovery time.
The surgery, to be performed by Dr. Lewis Yocum, represents a major setback for Oakland's young phenom, who was signed as a 16-year-old to a then-record $4.25 million signing bonus in 2008.
"He's very young, very talented," A's manager Bob Geren said. "I'm sure he'll bounce back fine. It's been a very successful surgery in our industry."
As a pro, Ynoa has pitched just nine innings due to various injuries throughout his brief career. In that time, he's struck out 11 but has also given up five runs on six hits and four walks.
