Thomas Ian Nicholas, who played Henry Rowengartner, the rocket-armed 12-year-old who lifted the Chicago Cubs to a World Series championship in the 1993 film "Rookie of the Year," will be in attendance at Wrigley Field for Game 4 of the NLCS against the New York Mets.

Nicholas, now 35, has thrown out the first pitch and sung "Take Me Out to the Ball Game" several times at Wrigley.

"Usually when I go to the game, I wear the jersey the Cubs made for me with my last name, Nicholas, on it, but I called the team and I said, 'Can you make a Rowengartner jersey for me?,'" Nicholas said. "I've never done that. I haven't worn a Rowengartner jersey since the movie, but I feel like we kind of need it right now. It's kind of like my rally cap."

Nicholas would have been at Tuesday's Game 3, but he had prior obligations. He was at Disneyland for most of the day celebrating his 4-year-old son's birthday.

"The last thing I want to do is spend the day at Disneyland and get on a plane at 7 a.m. to go to Chicago, but I'll do it for the Cubs," Nicholas said. "I wasn't planning on going out for the postseason, but after they won the wild card and then beat the St. Louis Cardinals, the excitement started to build with fans of the Cubs who are also fans of 'Rookie of the Year.' My Twitter feed started to get busier and busier during the postseason, and people started getting excited. I got excited, too."
