Coming off two injury wrecked seasons, Sizemore said he briefly worked out at first in Scranton but he doesn't even own a first baseman's glove.
"Rehab's just a grind," Sizemore said. "There's good days. There's bad days. If you get a couple bad days in row, where your knee is sore, it's swollen, it's just tough to kind of get through it. But then you have a good day and you're right back to the mindset: I'm good. I'm going to come back and get over this."
