CHICAGO -- It was easy to forget that Anthony Rizzo is just a kid as he aced his Wrigley Field entrance exam Tuesday with a pair of hits, including the go-ahead RBI in the Chicago Cubs' 5-3 victory, and some solid work over at first base.

“Which kid were you talking about?” manager Dale Sveum said after a second consecutive win over the New York Mets. “He didn’t act like much of a kid tonight, that’s for sure. That was pretty impressive.”

Afterward, though, the 22-year-old Rizzo kept his aw-shucks persona intact, namely when he was asked about what he thought about his first Wrigley experience.

“It was awesome,” Rizzo said. “My first thought coming here was sliding that green door open like Rookie of the Year, the movie. I didn’t see that. I got lost coming in. But it was a lot of fun today.”

Without even showing any of his acclaimed power game, Rizzo was still able to make a significant impression. He might have been playing in his first Cubs game, but it wasn’t his first major-league game and those 49 contests he played for the San Diego Padres last season seemed to make a difference already.

“You know, to be honest, before the game I was breathing a lot, taking deep breaths,” Rizzo said when asked if he had any butterflies before the game. “When I got it the box I just felt really good. It’s always a good feeling.”

He never looked jumpy or anxious at the plate and having some success right away seemed to make a difference. In his first at-bat he smoked a two-hopper that Mets shortstop Ruben Tejada bobbled. It was first ruled an error and then quickly changed to a single, sending the crowd from groans to cheers.

“The first at-bat getting that controversial hit [with] them changing it, I couldn’t have asked for a better start right there,” Rizzo said.

He was off and running. In his second at-bat he grounded out to first base to move runners to second and third with nobody out. The Cubs went on to score three runs in the inning.

“It’s something that we struggled with in those situations,” Sveum said. “Not only do we not get the hit, but we strike out and don’t move anybody along.”

Then to top things off in the fourth inning, he lined a base hit to center field on a 2-2 pitch for the go-ahead run. The hit was generously ruled a double showing that the new guy is already being treated like a star.

“Any time you come into a new clubhouse and you can contribute the first day or right away ... and doing that with two strikes was even better,” Rizzo said.

Starting Wednesday he can begin settling into a routine, but the spotlight still figures to be bright for a while. His teammates don’t seem to be minding the attention Rizzo has received as they seemed prepared for it.

As long as it doesn’t bother Rizzo, it won’t bother them.

“We don’t care so I hope he doesn’t care either,” Alfonso Soriano said. “This is it. This is the big leagues and what he did in the minors helped him to get to the big leagues. I hope that he continues working hard and proves himself here. The minor leagues is the minor leagues, but he has the talent.”
