The Phillies pitching depth too a little hit early. The team announced they have placed pitcher Zach Eflin on the 10-day disabled list, retroactive to March 30, with left and right knee tendinitis. 

Eflin, who will begin the season at Triple-A Lehigh Valley, had surgery on both knees last August to attempt to fix the chronic tendinitis that caused him to end his season last year. He was acquired as part of the Jimmy Rollins trade back in 2014 and made his major league debut last season, ending the season 3-5 with a 5.54 ERA in 11 games.

Eflin was supposed to be a part of a very deep pitching rotation at Lehigh Valley, joining Jake Thompson, Ben Lively, Nick Pivetta and Mark Appel, all who the Phillies view as potential future members of the big league rotation.

This isn't the first time Eflin has encountered knee pain in his career.  The right-hander has dealt with chronic tendinitis in both of his knees and was diagnosed with patellar tendinopathy in both of his knees and a stress fracture in his right foot.
