Ten days after it was made, the four-player trade between the Yankees and Seattle Mariners that put Michael Pineda in pinstripes and sent Jesus Montero and Hector Noesi to the Pacific Northwest is finally official. The finalization had been held up by visa problems that kept Montero from leaving Venezuela to take his Mariners physical. Those are now cleared up and Pineda, who went 9-10 for the punchless Mariners last year with a 3.74 ERA, will likely become the No. 2 arm in the Yankees starting rotation. GM Brian Cashman will have a conference call with the Yankee beat writers at 5 p.m., after which I will have a full story up on the website.
