The Chicago Cubs are hoping to bounce back from a tough loss on Friday when they take on the Cleveland Indians in Game 4 of the World Series on Saturday night, and they’ll once again have a great assortment of celebrities on-hand to help fire up the fans at Wrigley Field.

In the pre-game festivities, two Hall of Famers will throw out ceremonial first pitches. Greg Maddux and Fergie Jenkins, both of whom have had their numbers retired by the Cubs, will do the honors for Game 4 after Billy Williams threw out the first pitch in Game 3 of the series.

“God Bless America” will be sung by Julianna Zobrist, the wife of Cubs outfielder Ben Zobrist, and for the National Anthem, the Cubs will turn to John Vincent, who has become well-known for his ability to hold the word “free” in the final verse of the tune.

After Bill Murray’s seventh inning stretch turn on Friday, the Cubs will hand the reins for “Take Me Out to the Ballgame” over to another actor, as comedian Vince Vaughn will do the honors on Saturday night for Game 4.

First pitch is scheduled for 7:08 p.m. as the Cubs look to tie up the series, and the game will be televised on Fox.
