Pineda has been on the 15-day disabled list since May 6 with a right shoulder muscle injury, and has thrown bullpens of 20-30 pitches to this point.
He was 2-2 with a 1.83 ERA in four starts before serving a 10-game suspension, then sustaining an injury while tossing a simulated game in Florida. The Yankees are hoping to have Pineda join the big league rotation in June.
