PHOENIX — Comedian Will Ferrell will play every position while making appearances at five Arizona spring training games on Thursday.
He plans to play for all 10 teams involved.
HBO and Major League Baseball announced the stunt Wednesday.
Ferrell will travel to Mesa, Tempe, Scottsdale, Glendale and Peoria via helicopter. The event will be filmed for an upcoming HBO special in conjunction with the Funny or Die website co-founded by Ferrell.
HBO said Ferrell is dedicating his special to fighting cancer. He also will honor Bert Campaneris' fete of playing nine positions in a game five decades ago.
Starting times for four of the games were adjusted to make Ferrell's barnstorming tour possible.
Memorabilia collected during Ferrell's tour will be auctioned off at MLB.com, with proceeds going to College of Cancer and Stand Up to Cancer, according to HBO.
MLB Commissioner Rob Manfred said in a statement that "Major League Baseball is happy to take part in what will surely be a fun and memorable day for a great cause."
Ferrell is to appear in the following games: Seattle Mariners-Oakland Athletics to start at 12:05 p.m. PDT; Chicago Cubs-Los Angeles Angels at 1:10 p.m.; Cincinnati Reds-Arizona Diamondbacks at 2:10 p.m., San Francisco Giants-Chicago White Sox at 4:05 p.m.; and Los Angeles Dodgers-San Diego Padres at 6:15 p.m.
