Tanaka's throwing program advances to 90 feet

BALTIMORE -- Masahiro Tanaka has taken his rehab on the road, making 50 tosses at a distance of 90 feet on Monday at Camden Yards, and the Yankees right-hander is said to be pain-free.

"So far, so good," Yankees manager Joe Girardi said. "He's not throwing pitches, but he's at 90 feet and he let it go a little bit today."

Tanaka's next step would be to increase his throwing distance to make some tosses at 120 feet, something that Girardi said could happen as soon as Tuesday.

After that, Girardi said, "I think you start thinking about flat ground, and after that flat ground, you start thinking about a mound. I don't have a date for that."

Tanaka is aiming for a September return to the Yankees' rotation and hopes to avoid surgery to repair a partially torn ulnar collateral ligament.
