whiffer
Batter who misses
A whiffer is someone who whiffs—misses completely when swinging at something, especially a baseball pitch.
In baseball slang, a whiffer is a batter prone to striking out: He's been a whiffer all season.
The term can also describe a pitcher who racks up strikeouts, making batters whiff.
