Toni Elias took victory in a restarted Moto2 race at Indianapolis on Sunday.
The sick title leader shot from sixth to first at the second start and the Gresini Moriwaki rider, plus Aspar Suter's Julian Simon and Marc VDS Suter's Scott Redding soon pulled away from the field.
Simon took the lead from fellow Spaniard Elias through turn one on lap five, but the trio of grand prix winners remained locked together for most of the race - Elias ignoring his reduced physical state to pull an impressive outside pass to regain the lead through turn one with six laps to go.
Redding lost pace during the closing laps, but Elias was unable to shake-off Simon, whose red bike - frequently seen backing into corners - was rarely more than a few tenths behind.
And that's ultimately where Simon remained, having been unable to launch the pass needed to secure his first Moto2 win, while Elias took another step towards the inaugural title with his fifth victory of the year.
Redding was more than happy with his first Moto2 rostrum, while second in the championship Andrea Iannone was just under two seconds behind Redding in fourth.
The Speed Up rider is now 67 points behind former MotoGP rider Elias in the standings.
JiR's Simone Corsi charged from 39th on the restart grid to fifth, with Sergio Gadea sixth, Thomas Luthi Seventh and Gabor Talmacsi eighth.
Home wild-card Jason DiSalvo claimed a commendable ninth on his Moto2 debut, with a GP Tech-run FTR.
The former Triumph WSS rider crossed the line with his fist in the air just a few hundredths clear of Anthony West and Dominique Aergerter.
The initial race start had been red flagged on the opening lap after two separate multi-bike pile-ups at turn two.
Tech 3's Raffaele de Rosa and American Honda's Roger Lee Hayden were then told they would not be allowed to restart, since they did not return to pit lane within the allocated time limit.
It's the same rule that stopped Alvaro Bautista and Aleix Espargaro restarting the German MotoGP race.
American Honda team manager Kevin Schwantz and Tech 3's Herve Poncharal were soon seen in separate conversations with officials - Schwantz calmly explaining that Hayden had actually got back in time but returned via a short cut.
Just as Schwantz and Poncharal seemed to accept that their riders were out, a subsequent announcement declared that all riders would be allowed to restart!
de Rosa failed to finish, but Hayden salvaged 17th from his second chance. The third American in the field, Moto2 regular Kenny Noyes, was 19th.
