Despite suffering an injury that typically results in Tommy John surgery, the Yankees and Tanaka opted to use a six-week rehab program and possibly return this season. Now, getting another start from Tanaka this season is up in the air.
"Right now, it's too early to call," Cashman told ESPN New York 98.7.
New York manager Joe Girardi said before Thursday's game that the Yankees won't know "if he's going to be a pitcher for us" until Tanaka starts throwing again. He was shut down for three weeks after the injury and is expected to start throwing again at the beginning of August.
