David Robertson day-to-day with hamstring issue

David Robertson is day-to-day with “crankiness” in his left hamstring, Brian Cashman confirmed. He had an MRI today and it is not a DL situation.

Robertson, 28, limped off the field last night after apparently catching a spike during the follow through of his final pitch. He said afterwards he was fine, but the team send him for tests anyway. Robertson has pitched well this year (3.86 ERA, 3.54 FIP), and with Joba Chamberlain hitting the DL, the Yankees really can’t afford to lose their primary setup man.
