The reliever has been eagerly waiting for word from New York, where his wife, Erin, is expecting the couple's first child. Her due date was last Sunday, so Robertson admits he has been a bit on edge of late.
"I get a little nervous, especially when people text me in the morning at 9 a.m. and I'm still asleep," Robertson said. "I'm like, 'Uh-oh.' I've got my phone on loud, so I'm not sure who it is and I freak out for a second."
Robertson said he "can't wait" to welcome the newborn, which the couple already knows is a boy, but he said this "has been a bit of a nerve-rattling week" and urged his teammates to hurry to dress for the club's charter flight back to New York.
Robertson said that his concentration on the field hasn't been affected, though.
"When it comes to the game, when I'm in there, I'm not worried about anything else except getting my outs and helping us win the game," Robertson said.
