Brandon Nimmo sent the ball soaring toward the Chicago Cubs' bullpen and started sprinting.
"Hey, I've never hit a major league home run before, so I don't know what that feels like," he said. "So, out of the box, I'm going. I was floating around the bases there. I didn't know what I was doing."
The 23-year-old rookie's three-run homer in the fourth inning was one of five home runs by the New York Mets off Jason Hammel in a 10-2 victory Friday night that ended Jacob deGrom's 10-start winless streak.
Nimmo, who made his big league debut Sunday and played his first home game Thursday, pulled a 92 mph fastball to right-center for a 7-1 lead.
