"He's facing a pitcher and it's an at-bat," Girardi said. "He doesn't know what's coming, so it's an at-bat."
Girardi said he isn't sure when Rodriguez would be able to play in rehab games, but thinks he would need to run the bases "a little bit more" before taking that next step.
Still, rehab games might not be too far away.
"I'm not sure when he's scheduled to do that," Girardi said. "But obviously, if he's taking simulated at-bats, he's got to be fairly close."
