The Oakland Athletics will be without their starting pitcher Jarrod Parker for the entire season, reports CBS Sports.
Parker will require dreaded Tommy John surgery to repair a torn ulnar-collateral ligament in his right elbow - his pitching arm. As is the case with most MLB players undergoing Tommy John surgery, he is expected to miss all of 2014.
The 25-year-old will go under the knife for the second time having required Tommy John surgery in 2009 when he was still playing in the minor leagues.
Parker went 12-8 in 2013 with a 3.97 ERA, 1.22 WHIP and 134 strikeouts in 197 innings helping the A's to the AL West championship last season. He was expected to be the Opening Day pitcher this season.
News of Parker's injuries add to the pitching woes in the A's roster as they are already without A.J. Griffin, who is in the process of resting for three weeks with discomfort in his pitching elbow.
MLB correspondent Susan Slusser claims Scott Kazmir has had to be scratched with left triceps stiffness.
It means Sonny Gray and Dan Straily are the only healthy pitches in the original projection of the starting rotation for the A's. Tommy Milone is favourite to come in for Parker while Jesse Chavez is an alternative for Griffin.
Drew Pomeranz and Josh Lindblom could get the call if it turns out Kazmir needs a spell on the treatment table as well.
