Milton, who had surgery in June 2007, went 0-4 with a 5.17 ERA in six starts with Cincinnati last season. He could be ready to pitch in a minor league game in the next few weeks.
The Yankees signed Milton, 32, to a minor league contract on July 11, returning the pitcher to the organization that originally picked him 20th overall in the 1996 draft. He was traded to Minnesota two years later in the deal that sent Chuck Knoblauch to the Yankees.
Also, right-hander Victor Zambrano threw 46 pitches in his second simulated game, and Shelley Duncan batted. Duncan, a first baseman-outfielder, separated his shoulder while making a diving catch for Triple-A Scranton/Wilkes-Barre on July 1.
Free-agent left-hander Joey Eischen worked out, throwing 37 pitches.
Andrew Brackman, who had an appendectomy on June 10, is scheduled to throw off the mound Thursday. He was taken by the Yankees in the first round of the 2007 draft.
