Tanaka began experiencing soreness after a 49-pitch simulated game last week in Detroit, but he continued his throwing program by playing catch on Tuesday. Manager Joe Girardi was not sure how many pitches Tanaka would throw on Saturday or what the next step in his process will be, although it figures to be a simulated game.
"Let's just take that and see how it goes," Girardi said. "When he gets through that, I guess I'll decide what's next."
The Yankees have proceeded cautiously with Tanaka, who is hoping the rehab will help him avoid Tommy John surgery. Even as the 2014 season winds down and no matter New York's position in the standings, Girardi maintained that at some point Tanaka will throw in a game to test the elbow.
"He will pitch somewhere. He has to throw," Girardi said. "You can't wait 'till next spring."
