Underdahl gets a huge holeshot and gets out in front early. He stays in front for about 300 feet, then Arana powers around him and pulls away for the win.

Hector Arana Jr's incremental margins (negative if behind): 60ft(-0.027), 330 ft(0.024), 660ft(0.039), 1,000ft(0.068). MOV: 0.1567 seconds (approximately 40 feet).

Hines will have lane choice over Arana Jr. in the next round.
