"From what I've been told, his throwing program was right on target," Rothschild said, according to The New York Post. "He's on schedule to have a normal Spring Training and season. We'll have to monitor his rest and his elbow, but that goes for a lot of guys."
Tanaka was 12-7 with a 3.51 ERA in 24 starts last season, missing time because of right wrist tendinitis and a right forearm strain. He was diagnosed with a partial tear of the ulnar collateral ligament in his right elbow during the 2014 season, his first with the Yankees.
Several of the Yankees' pitchers have made appearances at the team's Tampa, Fla., complex in advance of the official Feb. 18 report date for pitchers and catchers, including Luis Severino, Michael Pineda and Nathan Eovaldi.
CC Sabathia appeared at the complex last week, and Rothschild also said that the left-hander "looks better than I've seen him in a few years," according to The Post.
