NHRA - National Hot Rod Association

Coming off back-to-back final rounds in Gainesville and Las Vegas, Clay Millican keeps rolling in Houston. Millican and his Mike Kloeber-led Advance Auto Parts team defeated Scott Palmer to reach the semifinals but they'll have their work cut out for them with a final four match against Brittany Force, who set the pace with a 3.678 in her win against Doug Kalitta.

Steve Torrence and Antron Brown, friends away from the track but serious rivals when the helmets go on, also advanced and will race each other for the 38th time. Brown holds a one-sided 28-9 record in head-to-head match-ups. 

Semifinal pairings (lane choice first): Brittany Force vs. Clay Millican; Steve Torrence vs. Antron Brown
