Barberio played two games with the Lightning in 2012-13, recording one shot on goal. The blueliner spent most of 2012-13 with the Syracuse Crunch, the Lightning's American Hockey League affiliate, where he had eight goals and 42 points in 73 games.
In the 2012-13 Calder Cup Playoffs, the 6-foot-1, 185-pounder had three goals and 15 points in 18 games, and led all defenseman in postseason points as the Crunch advanced to the Calder Cup Finals.
Originally drafted by Tampa Bay in the sixth round (No. 152) of the 2008 NHL Draft, Barberio helped the Norfolk Admirals -- then the Lighting's affiliate -- win the Calder Cup in 2012, and Barberio was named the winner of the Eddie Shore Award, given to the best defenseman in the AHL.
