ST. PETERSBURG, Fla. (AP) — Scott Dixon controlled his own fate and simply needed a smooth Sunday drive to win a sixth IndyCar championship.

He was a tactician as he followed Josef Newgarden around the streets of downtown St. Petersburg. So long as he kept Newgarden in his sight, Dixon would yank the crown away from the American and add another milestone to his illustrious career.

Newgarden won the season finale, using a spectacular two-car pass for the lead in a valiant effort to win a second consecutive title. Winning was not enough, though, to deny Dixon his coronation.

Dixon stealthily finished third in an easy drive to another title.

"They just shadowed us all day, it was the smart play," said Newgarden, who admitted his shot at the title was so slim it spoiled his mood the entire weekend.

Dixon was already looking forward to the next goal: A.J. Foyt's record seven titles.

"Six is good. Seven sounds better," Dixon said. "That's obviously going to be the goal. But it's tough, as you can see from the competition, even if you mess up just a little bit.

"Just have a smooth race, and that's what we did. Credit to Josef, he drove a hell of a race there and put us under a lot of pressure."

The 40-year-old New Zelander has won all six titles with Chip Ganassi Racing. Dixon has won two of the last three championships, a run interrupted last year when Newgarden won his second title.

Newgarden tied Dixon with his series-best fourth win of the season but Newgarden was in too large of a hole to catch his rival. Although Dixon at one time led the standings by 117 points, the final margin was a mere 16 points over Newgarden.

Dixon built his lead with three consecutive races to open the abbreviated and pandemic disrupted schedule.

Newgarden, winner of two straight at St. Pete, went to victory lane to congratulate his rival.

"I really don't know what I'd do different this year and I don't know what I'd ask my guys to do different. They were flawless," Newgarden said. "We just weren't able to get it done but we'll reset and we'll hit 'em harder next year. I promise you we'll be in the fight."

The season was supposed to begin seven months ago on these same streets before it was abruptly canceled 48 hours before the green flag. It came to a close in front of a sold-out 20,000 spectators, the largest crowd of the season for IndyCar.

Although IndyCar lost races in seven cities and had just one street course, Sunday's finale, still managed to complete a 14-race season. IndyCar became the first major motorsports series to make it to the checkered flag, relatively unscathed, and as stable as possible during a pandemic.

Stewardship from first-year series owner Roger Penske got IndyCar to the finish and Penske brought his awful inaugural season full circle with Sunday's finale. The last hurrah of a decent season was a dramatic error-prone ender in which three Andretti Autosport drivers ruined race-winning runs and Newgarden went down swinging.

The race was an Alexander Rossi runaway for the first 37 laps and then pole-sitter Will Power crashed for the first caution. Power, who was in a tight race for third in the final standings, threw his gloves in anger and admitted to driver error.

"I just lost it. Had a moment," he said. "I was definitely frustrated there, making a mistake and hitting the wall. It's my bad. It put us out of the race and that's a bad situation.

The Power crash triggered a span of three cautions over the next 10 laps, the third on a restart on lap 47 when brand new teammate Scott McLaughlin spun in his IndyCar debut. The New Zealander won his third consecutive Australian Supercars championship one week ago then journeyed to the United States to launch a new career at Team Penske.

McLaughlin's wreck also collected Rinus VeeKay, who still clinched rookie of the year on the day he was renewed for a second season with Ed Carpenter Racing.

McLaughlin finished 22nd, just two spots ahead of Power in last, but was thrilled with his 47-lap experience.

"Awesome. Far out. The best day of my life, besides my wedding," enthused the 27-year-old newlywed.

Rossi then triggered a tailspin for the Andretti organization when he spun on lap 70 spun in marbles while racing for the win. Rossi had been determined to extend a streak of at least one win a season that dates to 2006 when was Skip Barber's youngest champion at 14-year-old.

His long and frustrating season ended with a 21st-place finish for the Andretti Autosport driver.

"Just lost it. It sucks, this is the first time I've crashed while leading," Rossi said.

It got even worse roughly five minutes later when Marco Andretti was spun by Takuma Sato while racing for the final spot in IndyCar's bonus program. Andretti, the Indianapolis 500 pole winner, has not announced a program for 2021 and he was clearly furious as he paced outside his car in an incident that could have cost the race team $1 million in bonus money used toward next year's budget.

"We were in the money, so to say. I think I just got tagged," he said. "I've never seen a season like we've had this year with the misfortunes. Some of it is luck, and some of it is not. The prep for 2021 starts now."

James Hinchcliffe, in another Andretti entry that had run in the top three most of the race, then spun, as well, under caution.

"In 16 years of racing cars, I've never spun out under caution before. Just my fault," Hinchcliffe said, noting he made the spin even worse by hitting Andretti-aligned driver Jack Harvey as he re-entered the course.

"That's an even bigger black eye," he said.

The pace car, used at that point over an unusually quick run of cautions and six times for 26 laps, ran out of gas. Then Colton Herta — in yet another Andretti car — spun after running for the win most of the day with Rossi and Hinchcliffe.

He still managed to finish third in the final IndyCar standings but was annoyed he didn't win the race.

"I think we had a pretty good shot at a win and I just messed it up," Herta said.

Newgarden had control but soon Pato O'Ward was soon on his corner, looking for the lead. O'Ward couldn't execute a pass and Newgarden put space on the challenger by stretching his lead to nearly a full second with 10 to go.

The exiting champion was in cruise, but all the earlier attrition helped Dixon slip through the field to third. There was nothing Newgarden could do, even on a day he did everything he had to, to deny Dixon a sixth championship.

Dixon, considered the best of his generation, ranks third on IndyCar's all-time wins list behind A.J. Foyt — the series' only seven-time winner — and Mario Andretti. His first title was in 2003, his first season with Ganassi, and his latest championship comes as the team has welcomed NASCAR's seven-time champion Jimmie Johnson to the organization.

Ganassi next year will have the two most prolific drivers of their respective series on the same team.

Ganassi now has 13 total championships and Dixon said the team owner seemed concerned ahead of the race because so much of his points lead had been eaten away by Newgarden.

"He said before I got in the car, he just said, 'Don't worry, just do what you do,'" Dixon said of his boss. "That's what we did. We covered the bases we needed to.

O'Ward, in his first full IndyCar season, finished third in the race in five points out of third in the standings in what had been a tight battle between Herta, O'Ward and Power. Marco Andretti finished the season 20th, lowest of all the full-time competitors.
