Bentz grew up in Juneau, and he made history on April 7, 2004, by becoming the second pitcher, after Jim Abbott, to play in the Major Leagues after being born without one of his hands.

He played only four games for Florida in 2005, pitching only two innings, and allowing seven earned runs.

In 2007, Bentz was invited to spring training with the Colorado Rockies, but did not make the team.

In 2008, he pitched for the Bridgeport Bluefish of the independent Atlantic League before being released on July 2.

His weight then up to 265 pounds, Bentz was a running back for the NCAA Division III program.
