Todd Frazier 'worried' about 'new competition' at third

Cincinnati Reds third baseman Todd Frazier was an All-Star last season but he'll have a "new teammate" at spring training in Arizona Thursday who has him on guard.

That's right -- it's none other than celebrity star Will Ferrell, who will be playing for the Reds (among other MLB teams) as part of a Funny or Die special that will air on HBO later this year.

Ferrell, who's a big baseball fan, will play every position on the diamond for 10 teams as a tribute to Bert "Campy" Campaneris, who achieved the feat in a game back in September of 1965.

In the broader scope, Ferrell's pursuit is to promote donations and awareness in the fight against cancer.

Cincinnati takes on the Diamondbacks at 5:10 p.m. ET. Ferrell's day begins with a 3:05 p.m. ET clash between the Mariners and Athletics.
