DARLINGTON, S.C. - Brad Keselowski provided perhaps the biggest throwback at the Southern 500 - giving Team Penske its first victory at Darlington Raceway in 43 years.
"This is probably the biggest win of my career," said Keselowski, the 2012 NASCAR Cup Series champion.
Keselowski beat leader Kyle Larson out of the pits - "It couldn't have been more than 10 feet," Keselowski said - with 22 laps to go, then pulled away on the restart to sweep the weekend at Darlington.
Keselowski took the Xfinity Series race Saturday when leaders Ross Chastain and Kevin Harvick wrecked late. This time, Keselowski and his crew took advantage on the final caution to move in front with a fast pit stop.
Keselowski then did the rest as he opened a 1.5-second lead down the stretch.
It was Keselowski's first Cup Series victory of the season - and 25th of his career - and the first time a Penske driver had won at Darlington since Bobby Allison in the 1975 Southern 500.
"Got to give a lot of credit to my pit crew," Keselowski said. "Running second that last stop, and they nailed it."
They also put Team Penske in victory lane here for first time in decades in a race that has become stock-car racing's Old Timer's Day to celebrate its history. Keselowski drove a Miller Genuine Draft paint scheme that Rusty Wallace used when driving for Penske.
Walt Czarnecki, Team Penske vice chairman, said he was glad to break the long dry spell at Darlington and give the organization its 498th win across several platforms of racing.
"I've been in touch with (team owner) Roger (Penske), and he's about excited as can be," Czarnecki said.
Joey Logano, Keselowski's Penske teammate, finished second, and Larson was third.
Logano was grateful to see Team Penske on top.
"The one-two is nice," he said. "Racing Larson there, I was thinking it would be good to get a one-two. It would be really nice to be the one."
Larson won the first two stages and led 284 of the 367 laps, but he had to settle for his seventh top-three finish of the season instead of a win. Larson chose to focus on the strong showing.
"This is my fifth Cup season, and I've run second or third a lot, so I guess you get used to it," Larson said with a chuckle. "The disappointment, I can handle it better than most people."
Kevin Harvick was fourth and Chase Elliott fifth.
The Busch brothers were next - Kurt in sixth, series points leader Kyle in seventh - with Erik Jones, Jamie McMurray and pole-sitter Denny Hamlin rounding out the top 10.
Harvick leads the series with seven wins this season and stayed hot at Darlington despite starting 22nd. It was the 21st time in 25 races he has wound up in the top 10.
Jimmie Johnson struggled throughout the weekend at Darlington Raceway. He sustained some damage during qualifying and had to start from the back of the field for unapproved changes. He was assessed a pass-through penalty for a commitment line violation when trying to enter the pits, then had to go behind the wall with an oil pump problem that knocked him from the race.
A seven-time season champion, he does not have a win this year. While he's in the playoffs on points at the moment, he may have work to do at the final regular-season race at Indianapolis next weekend to reach the postseason. Hamlin and Aric Almirola clinched playoff spots with their points from the race, meaning there are two more spots to fill.
"I don't want to be in this position," Johnson said.
The nastiest wreck of the race was when Clint Bowyer slammed hard into Ryan Newman, who appeared to be slowing down to head into the pits. Bowyer hit hard into the wall twice before coming to a stop in the center of the track, and his No. 14 car was towed into the garage.
Bowyer was evaluated and released from the infield care center.
"He just stopped right in the middle of the race track," Bowyer said of Newman.
Track officials twice had to clear the grandstands because of potential severe weather threatening the area before the race began. Drivers were called to return to their cars about 45 minutes later and, after the singing of the national anthem, they were ordered back to safety. In all, the weather delayed the start of the race by about 45 minutes.
IndyCar: Sato wins
PORTLAND, Ore. - Scott Dixon salvaged his championship run with an improbable comeback Sunday at Portland International Raceway to take control of his race to a fifth IndyCar title.
Dixon finished fifth, far behind race winner Takuma Sato, but he put together the kind of drive that may define his season. He started 11th, was collected in an opening-lap crash, got penalized for speeding on pit road and twice drove through the field from 20th.
His Chip Ganassi Racing team was forced to change its strategy several times, and caution flags helped Dixon cycle ahead of the other championship contenders. He goes to the Sept. 16 season finale with a 29-point over Alexander Rossi.
Rossi had a decent race Sunday but finished eighth and lost three points to Dixon.
Team Penske drivers Will Power and Josef Newgarden started on the front row and are the only other drivers mathematically eligible to win the championship. Newgarden finished 10th, and it was a terrible day for Power, the reigning Indianapolis 500 winner. He had a mechanical problem eight laps into the race that seemed to make his car stall as he pulled out of the way and conceded the lead to Rossi.
Power later went off course into a tire barrier and finished 21st.
Sato also benefited from caution flags to win for the third time in his career and first since he won the Indianapolis 500 last season.
Ryan Hunter-Reay nearly caught Sato over the final two laps but wound up second. Sebastien Bourdais, the previous winner of an open wheel race at Portland in 2007, was third.
Formula One: Hamilton first
MONZA, Italy - Lewis Hamilton denied Ferrari a dream home win Sunday as he overtook Kimi Raikkonen with eight laps to go and earned his fifth Italian Grand Prix victory in seven years.
The Mercedes driver beat Raikkonen, who had started in the pole position, to tie Michael Schumacher's record of five Italian GP victories and extend his championship lead to 30 points over Ferrari's Sebastian Vettel, who had a nightmare start.
Valtteri Bottas was third in his Mercedes, ahead of Vettel and Red Bull's Max Verstappen, who received a five-second penalty.
Hamilton had started third, behind Raikkonen and Vettel after the Ferraris started on the front row, booking the top two places in Monza for the first time since 2000.
The championship leader put Vettel under pressure immediately, but Vettel pulled clear and was alongside Raikkonen into the first corner.
Hamilton had another go down the outside heading into the second chicane, inching ahead of Vettel when they made contact causing Vettel to spin.
The safety car was deployed, and Vettel went into the pits for a new front wing, coming out 18th.
Both drivers complained on team radio, but an investigation decided that no further action was necessary.
