Ferrell played in five games of Major League Baseball spring training on March 12, 2015 for 10 Cactus League teams as part of promoting a Funny or Die comedy/charity special. He played for the Arizona Diamondbacks, Los Angeles Angels, Los Angeles Dodgers, San Diego Padres, Cincinnati Reds, Oakland Athletics, Seattle Mariners, Chicago Cubs, Chicago White Sox, and the San Francisco Giants, playing all 10 positions, including designated hitter. According to Baseball Reference, Ferrell faced and retired one batter – pitching on behalf of the Dodgers and ending with a 0.00 ERA. The memorabilia from his one-day professional baseball career was sold and was auctioned and the proceeds were sent to two cancer charities. Ferrell went 0–2 with two strikeouts over the day, but managed to foul off a 92 mph fastball from the Giants' Jean Machi.
