'American Idol' winner Scotty McCreery was good luck for the Chicago Cubs this weekend, singing 'Take Me Out to the Ball Game' during the seventh inning stretch at Wrigley Field. The very next half-inning, the home team scored what proved to be the game-winning run in a 4-3 victory over the Cincinnati Reds.

"I can see why some people forget the words up here. You get nervous," McCreery told the Cubs' television announcing crew while assisting in the color-commentary after his performance. The two announcers joked that they usually tell people to "start low and start slow," but that advice wasn't necessary for the North Carolina born bass singer. "It was everything I dreamed of, I'm telling you," he said.

McCreery pointed out that he was wearing a No. 8 Cubs jersey, the same number he wore when pitching for his high school's baseball team before leaving for Hollywood in February. The three then went on to discuss baseball, the 17-year-old's pitching repertoire and how 'Idol' compares to Wrigley Field. "This is a lot bigger stage," he said. "Idol can be stressful, but this is a lot of fun right here."

The American Idols Live Tour stops in Columbus, Ohio, Pittsburgh, Penn. and Baltimore, Md. this week. McCreery releases the music video for his debut country single 'I Love You This Big' on Tuesday. Runner-up Lauren Alaina released her debut music video on Monday.
