In Focus: They skate hard

They use words like “jammers” and “blockers.” They don’t just skate, they skate hard.

If you haven’t witnessed roller derby, prepare yourself for a different kind of sport.

Dating back to the 1930s, it consists of five members on each team, featuring a “jammer” that attempts to pass the opponents as many times as possible by sprinting around the track and lapping the pack.

Steel City Roller Derby hosts its games at Romp N’ Roll in Shaler.

The league is celebrating its 10th season, with the Penn Bruisers taking on last year’s champions, Allegheny Avengers, March 19 in the 2015-2016 Battle of the Burgh Championship game.
