MLB: Yankees' Tanaka has partially torn elbow ligament

Masahiro Tanaka has a partially torn ligament in his right elbow, and the New York Yankees are hoping their rookie sensation will be able to pitch again this season.

General manager Brian Cashman says Thursday night that Tanaka could return in six weeks, but didn't rule out the possibility of surgery if the Japanese right-hander doesn't respond to a rehab program.

The injury is a huge blow to a battered Yankees rotation already missing CC Sabathia, Ivan Nova and Michael Pineda to injuries. Tanaka had been a stabilizing ace at the top of the rotation in his first season since arriving from Japan.
