The odds were astronomical. But it didn't matter.
On July 11, 1999, Diamondbacks infielder Jay Bell made a millionaire out of Chandler resident Gylene Hoyle in what remains today one of the most expensive swings ever taken.
The Diamondbacks paid homage to the anniversary of the event with a video posted to Twitter on Thursday.
Hoyle, then 31, won a radio contest sponsored by Shamrock Farms and was invited to the day's game between the Diamondbacks and Oakland Athletics. She was tasked with picking a Diamondbacks player to hit a home run and to pick the inning in which it would occur.
