Scott Dixon moved back into the IndyCar Series lead with a commanding victory at Mid-Ohio. The reigning champion eventually won by half a minute, having dominated the second half of the race after Dale Coyne's Racing Justin Wilson lost ground in the pits.
Wilson had pounced on pole-sitter Ryan Briscoe (Penske) to take the race lead early on, with Dixon running a quiet third. But the Target/Chip Ganassi driver ran longer than anyone else before his first stop, and consequently jumped ahead of Briscoe and closed right in on Wilson. Dixon then hounded the Briton until he was able to pounce and snatch the lead as Wilson tried to lap Milka Duno's Dreyer & Reinbold car just before half-distance.
Wilson then dropped out of contention for victory at the next stops, as his car ran dry coming into the pits and then struggled to restart, consigning him to a distant 13th-place finish.
With Wilson out of contention, Dixon was unstoppable, and he strolled away to clinch victory as Briscoe's tyres faded badly, leaving him with his hands full fending off Dixon's Ganassi team-mate Dario Franchitti for third.
Ryan Hunter-Reay claimed an outstanding fourth place for AJ Foyt's underdog team, ahead of Andretti-Green duo Hideki Mutoh and Marco Andretti, with Paul Tracy seventh on his one-off return to KV Racing while Mario Moraes attended his father's funeral.
Tony Kanaan went off the road early on but recovered to 10th for AGR, with Penske's Helio Castroneves only 12th after a spin. Danica Patrick was also in trouble, losing several laps due to a tangle with Mike Conway.
