The Yankees may be grooming Kevin Millwood to provide addition depth in their starting rotation. He threw 75 pitches over 5-plus innings Tuesday in his second extended spring training start. Millwood, 36, felt good after the outing and could pitch for Double-A Trenton or Triple-A Scranton/Wilkes-Barre. New York's Phil Hughes is dealing with velocity issues and the back end of the team's rotation is unproven.
