NEW YORK -- We might have watched the coming-out party of a new Bronx Bomber on Wednesday.

Greg Bird, the 22-year-old lefty-hitting first baseman just called up from Triple-A six days ago, smacked the first two home runs of his major league career. Better yet, he drove in all four runs in a 4-3 New York Yankees victory over the Minnesota Twins.

Before the game, Yankees manager Joe Girardi compared Bird to Miguel Cabrera, and Bird make Girardi look pretty smart with his performance.

"I said [earlier] today, he's got a slow heartbeat, and you can just see it," Girardi said afterward. "He doesn't go out of his zone, he knows what he wants to do and has a plan, and he executed really well today."

Bird's first blast came in the fourth inning, when he deposited an Ervin Santana 0-1 changeup into the second deck in right field. Carlos Beltran, who had singled just before Bird's at-bat, came home with him and the Yankees had a 2-0 lead. Starter Nathan Eovaldi had pitched four perfect innings at that point, and it looked like it could be a historic day in the Bronx.

By the time Bird came up again in the sixth inning, Eovaldi's bid for perfection was over and the Yankees trailed 3-2. Beltran was again aboard thanks to a two-out walk, and then Bird put the Yankees back in front by redirecting a 1-0 Santana fastball into the Yanks' bullpen in right-center.

"It feels good," Bird said. "It was a good win for us. A great team win. Nate threw the ball well; Carlos had some good at-bats in front of me. It was just a good win."

If that sounds like a rather low-key reaction to such a momentous occasion, you're right. It was.

"I just like to be even-keeled and level-headed, and just go out there and let the the work I do before the game take over," Bird said.

This is what Girardi was talking about before the game when he compared Bird to Cabrera, whom Girardi managed with the Florida Marlins back in 2006.

"Miguel Cabrera had a slow clock, and really had an understanding of what he wanted to do," Girardi said. "And I think Greg Bird has an understanding of who he is and what he wants to do."

It's been quite a week for Bird, a fifth-round draft pick in 2011 who began this season with Double-A Trenton and was called up from Triple-A Scranton-Wilkes Barre six days ago. He's batting .333 in his first five games in New York.

He got a big hit in the 10th inning of Monday night's win over the Twins, collected his first big-league RBI in Tuesday night's win and got the first curtain call of his baseball career after going deep for the second time Wednesday.

Girardi certainly isn't the only one impressed.

"His composure, his demeanor," Chase Headley said, when asked what he likes about Bird. "You feel like he’s been here for six months already."

He hasn't been, though. And it's important not to get too carried away. Since 1914, only two other Yankees have recorded a multihomer game within their first five major league games. But those players were Jesus Montero and Shelley Duncan.

Still, it's a feat well worth celebrating, although Bird said he didn't have any big plans for after the game.

"Get ready for tomorrow," Bird said. "My parents are in town still, so that'll be fun. But we've got another game tomorrow, and I think that's what everyone's focused on now."

He's probably wrong about that one. But he's got the right approach.
