Mishawaka's Sam Mook loves the Cubs.

And he shows it.

Mook's cubicle at Press Ganey in South Bend is a shrine to the team he idolizes, with Cubbies gear and memorabilia covering every inch.

It's why Mook is now a semifinalist to become the Ultimate Cubs Fan as part of the "Babe Ruth Ultimate 7th inning stretch Competition."

The field started with more than 1,000 applicants and is now down to just 50.

The winner gets to sing "Take Me Out to the Ball Game" on Labor Day at Wrigley Field.

"It would mean the word, everything to me," Mook explained.

"To lead 41,000 people on at Wrigley Field, all cheering for the same team---it would be magical."

And you can help Mook get there by voting for him at cubs.com. Voting begins and ends on Monday.

Mook's audition video of "Take Me Out to the Ball Game" will be one of five featured on Monday. If he receives the most votes, he will make the final 10.

Mook's favorite all-time player is Ron Santo. He looks up to Santo because of the way he has battled Type 1 Diabetes. Mook has Type 1 as well.

The 30-year-old admits he isn't the greatest singer in the world, but he doesn't have to be. He says he tries to channel the great Harry Caray.

Most importantly, he's hoping his passion for the Cubs will be enough to let him live the dream of singing during the 7th inning stretch at Wrigley Field.
