Shawn Kelley's Horse Head Good Luck Charm for Yankees

Scary.

Pitcher Shawn Kelley and his rubber horse head have become the new unofficial mascot of the Yankees. Since he started wearing this terrifying device during warmups, the Yankees have been on a roll. Hope you like the mask, Shawn, because it ain't going anywhere.

Could Kelley have picked up his inspiration for the horse head in Kansas City?
