baseball slang for a nice
curveball. For example,
"Here's the windup, Moyer's pitch on the way to Thome and it's strike three called! Jamie threw him a yakker that started at his head and ended up at his knees!"
- made-up quote from ALDS game 5, Mariners v. Indians, played October 15, 2001. The Mariners won the game, and the series, behind a stellar pitching performance by veteran junkballer Jamie Moyer.
