Baseball and Will Ferrell fans rejoice, for today Ferrell will be playing all nine positions during five different Spring Training games.

Ferrell and HBO teamed up with Major League Baseball to film a Funny or Die segment that will be dedicated to fighting cancer. As many baseball lovers know, MLB has teamed up with Stand up to Cancer to help fight cancer.

Ferrell will travel to Mesa, Tempe, Scottsdale, Glendale, and Peoria, Arizona and participate in the following games:

Mariners VS A’s
Cubs VS Angels
Reds VS Diamondbacks
Giants VS White Sox
Dodgers VS Padres

San Francisco Giants’ pitcher Madison Bumgarner asked if he would be able to pitch to Ferrell tomorrow during the game. Ferrell will be catching in the 5th inning for the SF Giants and Bumgarner is insisting on pitching to him.

“You don’t think I’ll be pitching in the 5th?” Bumgarner replied when SF Giants Manger Bruce Bochy told him that Ferrell will be catching then.

Ferrell isn’t a stranger to baseball games though. In 2010, he pitched a Triple-A (minor league) round under the name “Rojo Johnson,” for Texas, caused a brawl, and was ejected from the game.

Ferrell and HBO have not released many details for this project, but know Ferrell and the funnies of MLB will be something great for a good cause.

Here are some of the best reactions to Ferrell’s new project.
