Quick final pit stop helps Alex Palou win Long Beach Grand Prix

In six starts at Long Beach, Palou has never finished lower than fifth.

There is little room to maneuver on the 1.968-mile course with 11 tight turns, but after starting in the third position next to defending champion Kyle Kirkwood, Palou managed to sneak past Pato O’Ward into second place heading into the first turn on Lap 2.

“Making that move on the straightaway was big because I knew it was one of our only chances to get a pass on Pato,” Palou said. “I got that good run on that last corner and he didn’t expect it.”

This year marked the 51st edition of the longest-running major street race in North America, which started in 1975 as part of the Formula 5000 Series, switched to the CART/Champ Car World Series in 1984 and joined the IndyCar Series in 2009.

The top four qualifiers started on softer, high-grip “alternate” tires to establish position while the rest of the grid started on harder, more durable “primaries” to manage degradation on the 110-degree track surface. Of the 25 starters, 24 completed the 177.12 miles.

“We were going to make the two-stop strategy work but didn’t know if it would be doable or not,” Palou added. “As soon as I saw I couldn’t get Felix it was all about patience, fuel and waiting for the right time. I owe this win to my team. Without that pit stop I probably wouldn’t be sitting here now. It only takes one mistake to go from second to seventh but they’re great under pressure.”

Past winners Will Power and Josef Newgarden moved into the top two positions after Rosenqvist pitted but the Swede regained the lead when Newgarden pitted for the first time on Lap 37 and dropped back to 14th.

The first 45 laps were caution-free as Rosenqvist, Palou, Kirkwood, Malukas and O’Ward held the top five spots. Newgarden’s chances declined upon discovering a flat spot on his left front tire and he dropped back to 14th.

Rosenqvist’s three-second lead was erased when debris on the track exiting the Aquarium Fountain drew the only yellow flag all afternoon and narrowed the gap. Capitalizing on favorable pit position, Palou emerged from the lane just ahead of Rosenqvist.

After earning the pole position with a lap time of 1:07.4635 in qualifying, the runner-up had mixed emotions after leading for 51 laps with no win to show for it.

“You want to win when you have an opportunity but I’m proud of today,” Rosenqvist said. “We weren’t as good as Alex on the blacks… the last pit cycle was the defining moment. We had to come around 14, he had more of an opening and his crew nailed it. That happens.”

Kirkwood, who was vying for his third win in four years, finished right where he started in fourth.

“I had a good cushion and figured even with a bad stop I’d probably stay ahead but I knew there’d probably be a yellow at some point and there it came,” Rosenqvist lamented. “Considering Alex had primary [tires] also I think we would’ve been able to hold him off. It’s definitely disappointing when you can’t wrap it up.”

Dixon, who started in the position, earned his first podium this season and the 136th of his career.

“The race itself was a bit blah — I sat in the same position for most of it,” Dixon said. “Luckily for us we had it easy out of that last stop.”

Al Unser Jr. holds the record for most wins at Long Beach, chalking up six in eight years, including an unmatched four in a row from 1988-91.

Tom Sargent is becoming a fan of street circuits after two wins this weekend. Driving the Porsche 911 Cup for GMG Racing in the Mobil Pro Class, the 22-year-old Australian led from start to finish in Race 1 of the Carrera Cup North America on Saturday. In Race 2 on Sunday morning he again started from the pole position and claimed a 0.965-second victory over Aaron Jeansonne to complete the double.

In his last bid at Long Beach three years ago he hit the wall on Lap 2 but still finished second.

“Momentum in sports is critical and the past few weeks have been really cool for me,” Sargent said. “I didn’t do any street circuit racing before I came to the States. Maybe it fits my driving style.”
