Brad Keselowski beat points leader Kyle Busch in a tight and exciting battle to win the inaugural NASCAR Nationwide Series race at Iowa Speedway.
Although the JR Motorsports driver led nearly half of the distance, he had to face a strong challenge from Busch, who started from the rear of the field but stole the lead from Keselowski with 25 laps remaining, partly due to two new tires he took on a late caution, while Keselowski chose to stay on the track on a used set. The Joe Gibbs Racing driver seemed to be making the most of his fresher rubber when he got by the leader, but after the final restart with only 10 laps remaining, Keselowski got a run on Busch and retook the lead, then fended him off until the checkered flag.
"If I'd finished second I'd be kicking myself right now but it worked out and I'm feeling pretty good about it," said Keselowski about his team's decision not to pit on the penultimate caution. "Kyle was a little bit better on the short runs and he put those two tyres on and he had me. We were in trouble but just kept digging hard and forced the mistakes on Kyle's part and were able to drive by him."
Busch was left frustrated as yet another win slipped through his fingers on the closing laps. Not even tying Jack Ingram's record for most consecutive top two finishes with nine in a row, was of any consolation to the 24-year-old, who further stretched his lead in the standings.
"Just imagine if all those seconds were wins," said Busch, who has won three races in his last nine Nationwide Series outings. "Good battle, but our cars just wasn't good enough today, or I wasn't good enough -- probably me," said Busch. "We fought tight off [the corners] all day and then there at the end we were loose off. So I don't know what to do here with these races but very, very disappointing, very, very frustrating. I guess I just come here to finish second in these deals."
Jason Leffler was able to fend off former Nationwide Series champion Carl Edwards for third place, scoring his 14th top ten finish in the last 16 races. Behind Edwards, Kelly Bires rounded out the top five.
Penske rookie Justin Allgaier led the race early on but was involved in an incident with only 15 laps remaining when he made contact with Erik Darnell and Steven Wallace while battling for fourth place, managing just a 15th-place finish in the end .
Busch has now a 207 point cushion to Edwards in the championship, with Keselowski 165 behind the Roush Fenway driver.
