Yankees put newcomer Ackley on DL, Pineda out through August

NEW YORK (AP) The New York Yankees have put Dustin Ackley on the disabled list just five days after they got the infielder-outfielder in a trade with Seattle.

The Yankees made the move before hosting Boston on Tuesday night.

The AL East leaders also said ailing right-hander Michael Pineda isn't expected back until September at the earliest, and that rookie outfielder Mason Williams needed season-ending shoulder surgery.

Ackley is sidelined with a strain in his right lower back and could miss a month, or more if surgery is needed. He was 0 for 3 in two games for the Yankees, and is batting .212 with six home runs and 19 RBIs for the Mariners and New York.

The Yankees recalled right-hander Caleb Cotham from Triple-A Scranton/Wilkes-Barre.

Pineda went on the DL last week with a strain in his right forearm. He is 9-7 with a 3.97 ERA.

Williams injured his right shoulder in June diving into first base on a pickoff try.
