The IndyStar looks back at a decade of bruises and big wins for Naptown Roller Girls, which celebrate their 10th anniversary on Feb. 27. Their top-team, the Tornado Sirens, take on the Steel Hurtin' from Pittsburgh, at the Indiana Farmers Coliseum.

Flat-track roller derby is riding a global wave of enthusiasm, with teams competing on six continents. In Indy, there are four leagues — two for women, one for men, and one for girls ages 7-17 — and about two dozen statewide.

Doors open at 6 p.m. Saturday for a 7 p.m. bout. For tickets, visit naptownrollergirls.com.
