David Ross is one of four celebrities left, ready to duke it out in the semifinals round of Dancing with the Stars' 24th season. 

David is the first pro baseball player to ever appear on Dancing with the Stars, and at age 39 with seemingly no dance experience, he's probably surprised he made it this far with his professional partner Lindsay Arnold.

David is a recently retired MLB catcher who currently works as a special assistant for the Chicago Cubs team and TV baseball analyst for ESPN.

David is up against some tough competition, including fellow athlete Rashad Jennings. David would admit he's not the best dancer in the competition, but he certainly has stage presence, personality and determination. Can those traits carry him to the finals?
