Think you can throw harder than 49-year-old Colorado Rockies' pitcher Jamie Moyer? Head to the Fort Myers Miracle to find out.

The Class A affiliate of the Minnesota Twins is running a promotion in which fans can win a free ticket to a future game if they can top Moyer's 78 miles-an-hour on the radar gun. On the first day of the promotion last week, about 85 fans tried. None succeeded.

"I think some people look at the majors and they see guys throwing 90 and above, and they think 78 is super slow. But not a lot of people can throw 78 if they're not baseball players," Gary Sharp, the Miracle's director of media relations and promotions, told the FoxSportsNorth in Minneapolis-St.Paul.

The Miracle charges fans $1 for three throws to try to exceed the radar reading from Moyer's victory last week against the San Diego Padres, making him the oldest pitcher to win a major-league game.

Sharp said one fan in his 20s spent about $50 on the challenge and came close, but couldn't register more than 76 mph:

He kept trying over and over and over … He got more and more frustrated because his buddies that were with him were heckling him pretty good that he couldn't throw harder than a 49-year-old man.

The Miracle will continue the promotion throughout the season, including tonight's game against the Palm Beach Cardinals, Sharp said. Perhaps it can eventually benefit Moyer's charitable foundation, he added.

Moyer gave up one run in six innings in a no-decision in Pittsburgh on Tuesday, lowering his ERA to 2.28.
