The Cubs had some big names on hand for Aroldis Chapman's debut

It's an exciting season for the Chicago Cubs, the majors' winningest team at this point in the season.

Wednesday, that excitement was ratcheted up even more as the Cubs newest acquisition -- flamethrowing closer Aroldis Chapman -- made his debut.

He wasn't the day's only attraction, however.

Michigan football coach and former Chicago Bears QB Jim Harbaugh was around to throw out the first pitch (and seemed to do a fine job of it).

New Chicago Bulls shooting guard Dwyane Wade, sporting a black Bulls hat, was on hand with his actress wife Gabrielle Union.

And Charles "Peanut" Tillman, who was drafted by the Chicago Bears in 2003 and retired just last week, had "Take Me out to the Ball Game" duties.

The best part of that was either his emphasis on "peanuts and cracker jack" or holding the final note so long that he fell over.

Clearly, it's a fun time to be a Cubs fan.
