Acronym for Fielder Allows Runner To Score Like A Moron.
An
baseball play in which a defensive fielder makes an embarrassing combined mental and physical blunder that allows one or more base runners to score. A simple error alone does not qualify - there is an added layer of moronity on
top of the play, where the
player involved has momentarily stopped playing
baseball.
Examples include arguing with an umpire while holding the ball and not paying attention to the runner, missing a catch and then angrily throwing your glove on the ground and stomping away, or catching a pop fly for the second out, but thinking that it's the third out and casually throwing the live ball into the stands.
Benny Agbayani committed a FARTSLAM when he caught a fly
ball, and thinking there were three outs, gave the
ball to a
fan, which allowed the runner to score, and Agbayani had to ask for the ball back.
