Grapevine: Rankings: Power moves in to top 10

The Penske driver took his fifth win of the year to increase his lead at the head of the championship and also gained six places in the Castrol Rankings as he climbed from 15th to ninth.

He led home Ganassi drivers Scott Dixon and Dario Franchitti, the defending champion remaining sixth while Dixon dropped a spot to 10th.

Power was the highest-placed mover this week, meaning that Red Bull Formula 1 driver Sebastian Vettel maintained the top spot for a 22nd consecutive week.

Gary Paffett (49) led home his AMG Mercedes team-mate Paul di Resta (46) in the DTM race at Zandvoort. The British pair gained 11 and 10 places respectively and are now the two highest-ranked drivers in the series.

Also doing the business in the Netherlands was Edoardo Mortara (89), who became the highest-ranked F3 driver thanks to a Euro Series victory that gained him 15 places. Race two winner Antonio Felix da Costa (342) made up 84 spots.

Tom Onslow-Cole's results at Silverstone, a win, a second and a third, moved him into British Touring Car title contention and brought him up 96 places to 249th in the Castrol Rankings. Series leader Jason Plato (170) took only one podium from three races and fell 19 spots.

Strakka Racing's landmark first overall Le Mans Series win for an LMP2 car at the Hungaroring elevated drivers Danny Watts and Nick Leventis 140 places each to a share of 294th. Jonny Kane, who also raced the car, made up 112 spots and is eight places further up.

Stateside there was a maiden American Le Mans Series win for the Drayson Lola team, Paul Drayson (340) and Jonny Cocker (232) each gaining over 130 places.

There was also a fifth Indy Lights win of the year for championship leader Jean-Karl Vernay (150), who gained 13 spots as he dominated at Sears Point.

Most impressively, Kyle Busch landed a major success as he became the first driver in NASCAR history to win Sprint Cup, Nationwide Series and Truck Series races on the same weekend, all his wins coming at Bristol.

Busch, a past master of the half-mile oval, only gained one place as he moved into 17th. Championship leader Kevin Harvick (11) continued his advance as he swapped places with Denny Hamlin (12) and is now the second highest-ranked NASCAR driver behind four-time Cup champion Jimmie Johnson (5).
