Will Power in full force in rain shortened ABC Supply 500 at Pocono

Will Power delivered with great strategy and a determined drive to win a rain-shortened ABC Supply 500 at the Pocono Raceway.

The Aussie took the green flag in fifth as Simon Pagenaud leapfrogged the top three starters of Josef Newgarden, Alexander Rossi and third place starter Scott Dixon.

Calamity ensued heading to the second turn when Takuma Sato came together with second-place starter Alexander Rossi midway through the Long Pond Straightaway which collected Ryan Hunter-Reay. Felix Rosenqvist got tagged and nearly careened into the catch fencing while James Hinchcliffe crashed further back.

All five drivers walked away from the accident, and were evaluated at the medical centre. Rosenqvist was transported by ground to a local hospital, where he was evaluated and released.

Power punctured a tyre after running over debris under the yellow and surrendered his top-five position to take four fresh tyres. Meanwhile, Team Penske teammate Pagenaud lead the field to the green flag.

The 2019 Indy 500 champion cleared the field on the restart as Scott Dixon moved into second place over Newgarden rode in third. The top three ran unchanged throughout the stint until Pagenaud and Dixon made their first pitstops on Lap 37.

The remaining Team Penske drivers of Newgarden and Power took turns leading one lap a piece before making their pitstops on Lap 39 and 40.

Spencer Pigot smacked the wall in Turn 1 just as Power pitted which brought out a full-course yellow. Pagenaud re-assumed the lead ahead of Power, Dixon and Ferrucci.

A few backmarkers stopped under the yellow in preparation for the Lap 45 restart.

The Penske pair ran side by side through Turn 2 before Pagenaud came out ahead. Power got another run on his teammate two laps later to take the lead.

A game of cat and mouse broke out between the Penske duo while Pagenaud emerging as the leader on Lap 51. The Frenchman continued his blistering pace from before and stretched out to a .8193 second lead over his teammate.

Power eventually found his way past Pagenaud again as the pair got held up by Hinchcliffe's wounded car before making his pitstop on Lap 71. He lost further ground on pit road when he had to slow down to allow Marco Andretti in his pit stall.

Power's early stop allowed him to stretch his fuel a tad longer than his teammate, but lost his shot at the lead  the yellow flew on Lap 74 for Colton Herta's crash.

The yellow allowed Power to stop under the yellow along with Carlin Racing teammates Charlie Kimball and Conor Daly and Tony Kanaan. That promoted Dixon to the lead ahead of Dale Coyne Racing teammates Ferrucci and Sebastien Bourdais, Newgarden and Ed Carpenter while Power emerged in seventh.

Dixon left Ferrucci behind on the restart with a rearview mirror full of Pagenaud as Power and Carpenter leapfrogged Newgarden to take fourth and fifth.

Power eventually moved past Carpenter for fourth as Dixon stretched out a comfortable one-second lead over Ferrucci who in turn had one second over Pagenaud.

The top three gapped the field as reports of bad weather surfaced as the race reached half of its scheduled distance. That meant another round of stops which got kicked off when Newgarden peeled in on Lap 102.

Ferrucci and Carpenter were next on Lap 105 followed by Dixon surrendering the lead on Lap 106 to Simon Pagenaud, who in turn stopped on Lap 106.

The Frenchman's Team Penske crew delivered a blitzing fast pitstop which allowed him to move ahead of Ferrucci for what effectively was second place.

Power meanwhile had enough E85 Ethanol to remain on track and make up time while turning laps quicker than those who had already stopped before ducking in on Lap 110.

He re-entered the track on Lap 110 in second place behind Dixon and ahead of Pagenaud and Ferrucci. Power then showed determination as he clicked off the quickest lap of the race and set his sights on Dixon.

He overtook the Chip Ganassi Racing driver heading into Turn 1 on Lap 115 and left him in the dust despite having to navigate through lapped traffic and by lap 125 had built a six-second lead.

All would come to a halt on Lap 127 as lightning in the area prompted INDYCAR officials to display the red flag.

The race was called after 30 minutes of waiting as conditions worsened.

The win is the 36th of Power's 13-year career and his third at the 2.5-mile superspeedway. He admitted that the circumstances dealt to him forced him to stay strong-minded to get to the front.

"I passed a lot of cars and saved a lot of fuel," he said. "Obviously we topped off so we had a few laps in hand. We pushed through the sequences and that is how we jumped more cars. We caught a great yellow (flag) which moved us to second, and we caught a bad one, and that moved us back to seventh. The car was fast enough that I knew if we got to the top five, we would have a shot at the win."

Dixon settled for second as Pagenaud rounded out the podium. Ferrucci matched his career best IndyCar finish of fourth while points leader Josef Newgarden came home fifth.

Owner-driver Ed Carpenter finished sixth ahead of Sebastien Bourdais in seventh while AJ Foyt Racing driver scored his first top ten since Indianapolis with an eighth place effort.

Graham Rahal and Charlie Kimball rounded out the top ten.
