Mackey Sasser was a catcher for the New York Mets when his yips started showing up. In 1989, just two years into his professional career, Sasser started having problems throwing the ball back to the pitcher. As you can imagine, a catcher who can't throw the ball back to the pitcher isn't much of a catcher at all.
Sasser fans weighed in on the problem by calling radio stations suggesting ways to cure Sasser's problems [source: Baumbach]. Unfortunately, none of them helped. Sasser played for several other teams before leaving baseball, uncured of the yips, in 1995 [source: McCarron]. As with other players, a new term was coined to describe a catcher who can't throw the ball back to the pitcher: Sasseritis. Pretty original, huh?
After leaving the major leagues, Sasser worked with a therapist to help cure his case of the yips and went on to be a baseball coach at Wallace Junior College [source: Inside the Zone]. Sasser not only beat his yips after he stopped playing professionally, but he also tries to help other players who are having similar problems. Sasser has been known to give out his phone number and he answers e-mails every week from players with the yips [source: Baumbach].
