Michael Pineda was acquired via trade this offseason, sending top prospect Jesus Montero to Seattle. He had just come off of a solid rookie campaign, throwing 170 innings to the tune of a 3.74 ERA and 1.099 WHIP. He also had an impressive 9.1 K/9 rate.
The Yankees have yet to reap any benefits from the trade.
The team announced that the right-hander has a labrum tear in his pitching shoulder. He will undergo arthroscopic surgery Tuesday in New York. The typical time for rehab is one full year.
General Manager Brian Cashman certainly did not sound pleased. "This is a massive decision gone wrong right now," Cashman said Friday. "So all scrutiny is fair."
As it stands right now, there are six pitchers for five rotation spots. Barring another injury, either Freddy Garcia or Phil Hughes will need to exit the rotation once Pettitte returns.
