Dario Franchitti's IndyCar win at Mid-Ohio moved him into sixth place in the Castrol Rankings, ahead of F1 champions Jenson Button and Fernando Alonso.
The Chip Ganassi Racing driver beat Will Power's Penske machine thanks to superior pit work from his crew, handing him his second win of the season. Power's runner-up spot enabled him to continue his rise up the Castrol Rankings. He moved up five spots into 16th.
Power's teammate, Ryan Briscoe, fared worse as he failed to repeat his win at the corresponding race last year and slipped a spot to 11th behind rally ace Mikko Hirvonen.
Among the surprise stars at Mid-Ohio were Alex Tagliani (127), who finished fourth in his FAZZT Dallara and made up 38 places, and Simona de Silvestro (169), whose career-best eighth allowed her to pick up 27 spots. While De Silvestro was storming, her fellow female Danica Patrick was sliding, a poor 21st-place finish making her the biggest faller in the top 100 as she slipped 13 places.
Juan Pablo Montoya (26) ended a three-year winless streak in the NASCAR Sprint Cup at Watkins Glen and made up two places as a result. Series leader Kevin Harvick was unable to improve on his 15th place in the Castrol Rankings.
Bruno Spengler increased his DTM series lead with a win at the Nurburgring, and moved up 11 spots to 47th. Champion Timo Scheider's (62) inability to repeat his victory of a year ago ensured that he dropped 12 places.
Freddy Loix (239) jumped up 88 places as he made it two wins from two IRC starts at Rally Madeira, the Belgian leading a Skoda 1-2-3. Azores winner Bruno Magalhaes (207) crashed out and slipped 49 spots.
