He was drafted by the Marlins in the ninth round of the 2008 MLB draft.

Returning to Jacksonville in 2010, Jennings was suspended for 50 games for violating minor league baseball's policy banning the use of performance-enhancing drugs.

Jennings later thanked Pirates fans on Twitter for their support after the crowd at PNC Park gave Jennings a standing ovation when he was carted off the field and gave the crowd a wave.

He returned to the Marlins shortly thereafter, passing concussion protocol and sustaining no permanent injury.
