Harrison returns to York after being acquired by the Revs from Winnipeg of the Northern League late last season. He batted .362 in 10 games with York, and his four hits in his debut game marked the most ever by a Revs batter in their first game with the team. Two nights later, he ended the home regular season finale with a walk-off homerun, helping the Revs defeat the Lancaster Barnstormers on Fan Appreciation Night. Harrison played eight games at third base with York, and two games at second base.

Harrison was a 13th-round draft pick of the Tampa Bay Rays out of the University of Kentucky in 2001. He blasted 19 homeruns for Single-A Charleston in 2003 ranking fourth in the South Atlantic League in homers, and combined to slug 16 homeruns between High-A and Double-A the following year. He has also played at the Double-A level in the Florida Marlins and New York Mets organizations.

Harrison has starred in the Northern League the last three years, and batted .319 in 2008 and .322 in 2009. A natural athlete, he was recruited by the University of Kentucky to also play football, but chose to concentrate on baseball after two seasons with the Wildcats football squad.
