Toomas Heikkinen's dominance of this Global Rallycross season has been well documented, with his five consecutive victories and seven consecutive podiums the biggest story of the 2013 season. In that span, Heikkinen has also opened up a dominant lead in the SYLVANIA SilverStar zXe Cup, bringing him to the cusp of a $20,000 bonus to be awarded on September 22 at Charlotte Motor Speedway.

In Saturday's SYLVANIA SilverStar zXe Global Rallycross at Atlanta Motor Speedway, Heikkinen won the third race of the program, beating Tanner Foust and Sverre Isachsen in a repeat of the X Games Los Angeles podium.

It was Heikkinen's third win in three zXe Cup events, the others coming at New Hampshire Motor Speedway on July 11 and Bristol Motor Speedway on July 20. With 63 points, he holds a dominant 20-point lead in the four-race chase.

Ken Block, who had entered Saturday's event only nine points behind Heikkinen, maintained second place in the standings with 43. He and Heikkinen qualified first and second, and each won both of their heat races, setting up a great challenge in the final. But a broken hose clamp at the start of the main event forced Block to pull off immediately, relegating him to eighth place.

Four drivers—Heikkinen, Block, Tanner Foust, and Brian Deegan—remain mathematically eligible for the zXe Cup in Charlotte. Foust finished second in Atlanta, chasing down Heikkinen until a flat left front tire with three laps to go mitigated his chances. Deegan ran third for most of the final until a mechanical failure ended his race after five of 10 laps.
