The stakes were a tick lower for both prospects during the fourth inning of Monday's Grapefruit League game, in which Harper's only plate appearance against Harvey resulted in a walk. But that did not stop Harvey from taking notes.
"I try and pay attention to it," Harvey said. "You never know who you're going to face down the road or next time out. You can learn from each at-bat."
If everything breaks as the Mets and Nats envision, those two will be facing each other in the National League East for years to come. Harper ranked second on MLB.com's 2012 Prospect Watch, with Harvey clocking in at 38th overall.
