Australian Will Power battled back from a lap down Sunday to win the IndyCar race at Pocono Raceway in Pennsylvania for the second straight year.

Power held off his Penske teammate Josef Newgarden by 0.5268 of a second to claim his third win of the season.

His 32nd career victory in the series saw him break out of a three-way tie with retired greats Dario Franchitti and Paul Tracy for ninth on the all-time list.

Power was running in sixth place when he pitted on the 66th lap to replace his car's front wing assembly.

The unscheduled stop left the 2014 IndyCar champion a lap down, but he methodically worked his way back onto the lead lap shortly after the halfway point of the 200-lap race on the 2.5-mile (4 km) oval.

A speedy pit stop on the 165th lap saw him emerge from the pits as the leader and he held of hard-charging Newgarden for the win.

Andretti Autosport's Alexander Rossi rounded out the podium. Simon Pagenaud finished fourth and Tony Kannan was behind him to wrap up the top five.

With his runner-up finish, Newgarden retained the championship lead with three races left in the 17-race season.

With 494 points, Newgarden holds an 18-point lead over Chip Ganassi Racing's Scott Dixon of New Zealand, who finished sixth.

Brazilian Helio Castroneves is third in the standings, 22 points behind Newgarden after a seventh-place finish.
