For Power, it was his 29th career win which tied him with Helio Castroneves and Rick Mears for 11th all-time on IndyCar's all-time win list. The initial Texas race last June was rained out after 77 laps and rescheduled for this Saturday night (Aug. 27). What more could happen?
Defending race victor Ryan Hunter-Reay finished third, Josef Newgarden was fourth and Sebastien Bourdais fifth thanks to late-race pit strategy.
A year ago, Hunter-Reay won a crash-filled race at Pocono that took the life of Englishman Justin Wilson.
Hunter-Reay lost control of his No. 28 Andretti Autosport Honda in Turn 1 during first practice and was unable to make a lap during IndyCar qualifying, already putting the 2012 IndyCar champ in an early hole.
The complexion of the race and the points race changed after Pagenaud crashed while running 12th to bring out a caution.
Power then took the lead, and after a debris caution on lap 176, Power exited the pits in first place as Hunter-Reay got back on the lead lap with once last chance.
This was huge in the points, as Power - second in the points - led the field back to the green with just 36 laps to go.
Aleshin tried to challenge one final time, but Power pulled away over the final 20 laps.
The 29-year-old driver from Russian Federation was fastest in the 90-minute morning practice session and followed it up during qualifying in the afternoon. Just not quite fast enough.
Aleshin turned a fast two-lap average of 220.454 miles per hour on Saturday in his No. 7 Schmidt Peterson Motorsports Honda to edge Josef Newgarden for the pole.
It is the first career pole for Mikhail Aleshin, with Josef Newgarden in a Chevrolet beside him. "I just wanted this win so bad".
PIT FALLS: Helio Castroneves, Alexander Rossi and Helio Castroneves were involved in a freakish pit road accident on Lap 63.
Brown's auto rattled and lost traction early while Force's dragster backfired and released the parachutes just a little farther down track than Brown, allowing her to coast to the finish line in front.
"I can't help but feel like that 28 DHL Honda should have been in Victory Lane today", Hunter-Reay, the 2014 Indy 500 victor, said.
When he missed the season opening race at St. Petersburg, Florida due to an inner-ear infection, Power feared his season may have been lost before it even began. Just have to smile and keep pushing. It's been that way. "I love winning 500-mile races and this is one of the toughest ovals that we race on". "We just had a crash, the vehicle bottomed and it went into the wall", Pagenaud said after being released from the infield care center. The Indianapolis 500 victor climbed into the top five early in the race and remained there until a first series of green-flag pit stops but was eliminated in the pit road incident.
On Lap 64, Alexander Rossi, Charlie Kimball and Helio Castroneves were involved in a wreck on pit road.
