Kyle Larson was fastest in the second Sprint Cup practice for the season finale Ford EcoBoost 400, which was shortened by rain.
Both Cup practice sessions have been shortened by rain so far.
Larson put up a speed of 176.010 mph on the first of 25 laps around Homestead-Miami Speedway.
Filling out the top five was Kevin Harvick (175.194), Carl Edwards (174.374), Greg Biffle (174.126) and Joey Logano (174.081)

NASCAR is implementing changes to Cup cars that strengthen the right side door area and soften the frontal area after reviewing the crash between Kyle Larson and Ryan Preece at Talladega Superspeedway in April.
The changes are to be in place for the July 9 race weekend at Atlanta Motor Speedway.
Larson and Preece were uninjured in the vicious crash late in the race at Talladega. Larson’s car was turned and slid down the track to the apron before coming back up in traffic. Preece’s car slammed into the right side door area of Larson’s car.
Dr. John Patalak, NASCAR vice president of safety engineering, said the difference in velocity of the two cars at the time of impact was 59 mph.
“It’s pretty hard to find that on the racetrack normally,” Patalak told reporters Thursday during a briefing.
The severe impact moved a right side door bar on Larson’s car. NASCAR announced last month that it was allowing teams to add six right side door bar gussets to prevent the door bars from buckling in such an impact.
Thursday, NASCAR announced additional changes to the cars. The changes come after computer simulations and crash testing.
NASCAR is mandating:
Patalak said that NASCAR had been working on changes to the car since last year and did crash testing in January at the Transportation Research Center in East Liberty, Ohio. NASCAR did more work after that crash test.
As for the changes to the front of the car, Patalak said: “From an engineering standpoint we’re reducing the buckling strength of those individual parts and pieces. The simplified version is we are increasing the amount of crush that the front clip will be capable of. That’s all an effort to reduce the accelerations that the center section and driver will be exposed to during these frontal crashes.”
Adding the steel plate to the door bars is meant to strengthen that area to prevent any type of intrusion or buckling of the door bars in a similar type of crash.
Patalak also said that NASCAR inspected the car of Blaine Perkins that barrel rolled during the Xfinity race at Talladega in April. Patalak said that NASCAR consulted with Dr. James Raddin, Jr., who was one of the four authors of the Earnhardt investigation report in 2001 for the sanctioning body, in that incident.
Brad Keselowski surprised many when he didn’t re-sign with Team Penske in 2021. Penske was his home since 2010, and the team who helped him to a Cup Series championship in 2012. But Jack Roush offered Keselowski something Roger Penske couldn’t — ownership stake in the team.
Keselowski knew an RFK Racing revival would be an challenge, but also that he was prepared for it.
“I’ve been studying my whole life for this moment, and I’m ready for the test,” Keselowski said during the announcement of the new partnership.
Roush Racing entered Cup competition in 1988. It didn’t win that first year, but the company collected at least one checkered flag every year from 1989-2014 — except for 1996.
Roush was one of the first owners (along with Rick Hendrick) to appreciate the advantages of multi-car teams. By 2003, Roush Racing fielded five full-time teams. In 2005, all five Roush cars made the playoffs, accumulating 15 wins between them. Their dominance prompted NASCAR to limit teams to four cars. That limit remains today.
Roush sold half the team to Fenway Sports Group in 2007. The renamed Roush Fenway Racing team, however, never reached the highs of 2005 as the graph below shows.
The 2015 season was Jack Roush’s first winless season since 1996. By the time Ricky Stenhouse Jr. won two races in 2017, RFR was down to two cars. The company had four consecutive winless seasons before Keselowski came on board.
Keselowski is a perfect choice to drive the RFK revival. After all, how many other NASCAR drivers run a 3D-printing business? Or worry about having enough properly educated workers for 21st century manufacturing jobs?
“I feel like I’m buying into a stock that is about to go up,” Keselowski said.
The new RFK Racing team started off strong at Daytona, with Keselowski and teammate Chris Buescher each winning their Duels. During that week, NASCAR confiscated wheels from both drivers’ cars. Despite concerns about the team’s modifications, NASCAR ultimately levied no penalty. But after the fifth race of the year at Atlanta, NASCAR docked Keselowski 100 points for modifying single-source parts. Keselowski needed to win to make the playoffs.
It wasn’t Keselowski, but Buescher who won the first race under the new name. Unfortunately, Buescher’s Bristol win came too late to make the playoffs.
Keselowski finished 2022 ranked 24th, the worst finish since his first full-time season in 2010 when he finished 25th.
In the table below, I compare Keselowski’s finishes for his last two years at Team Penske to his finishes with RFK Racing in 2022 and the first 15 races of 2023.
Keselowski’s lack of wins since switching teams is the most obvious difference; however, the falloff in top-five and top-10 finishes is even more significant. Keselowski was not only not winning races, he often wasn’t even in contention. In 2020, Keselowski finished 91.7% of all races on the lead lap. In his first year with RFK, that metric dropped to 61.1%.
On the positive side, his numbers this year look far better than his 2022 statistics. Keselowski finishes on the lead lap 86.7% of the time and already has as many top-10 finishes in 15 races as he had in all 36 races last year.
Keselowski’s top-five finish rate improved from 2.8% in 2022 to 20.0% this year. That’s still off his 2021 top-five-finish rate of 36.1%, but it’s a step forward.
I summarize the last four years of some of Keselowski’s loop data metrics in the table below.
In 2022, Keselowski was down between six to seven-and-a-half points in starting, finishing and average running positions relative to 2021. This year, he’s improved so that the difference is only in the 2.6 to 3.6-position range.
Ford is playing catch-up this year, having won only two of 15 points-paying races. Ryan Blaney, who won one of those two races, has the highest average finishing position (11.3) among drivers with at least eight starts. Keselowski is 14th overall with a 15.7 average finishing position, and fourth best among Ford drivers. Buescher is finishing an average of 1.2 positions better than his teammate.
Kevin Harvick is the top-ranked Ford driver in average running position, coming in sixth overall. Keselowski is 13th overall in average running position and the fourth-best among the Ford drivers.
Average green-flag speed rank is the average of a driver’s rank in green-flag speed over all the races for which he was ranked. Harvick is the fastest Ford as measured by this metric, ranking eighth among all drivers who have completed at least eight races. Keselowski is the fifth-fastest Ford, but the 20th-ranked driver in average green-flag speed rank.
The other issue, however, is particular to Keselowski: He is involved in a lot of accidents. That’s not new with Keselowski’s move to RFK Racing. Since 2016, Keselowski has been involved in at least eight caution-causing incidents every year.
What may be new is that he has a harder time recovering from non-race-ending incidents now than he did at Penske.
In 2021, Keselowski was involved in 12 caution-causing accidents. Last year, it was 10 (nine accidents and a spin). He’s already been involved in 12 incidents this year, the most of any full-time driver.
Keselowski isn’t too concerned about accidents. He views them as a consequence of pushing a car to its limits. His competitors, however, have called him out for for his aggressive driving style.
Neither accidents nor Keselowski’s attitude toward them changed with his transition from Team Penske to RFK Racing.
Except now he’s the one paying for those wrecked cars.

NASCAR has docked Erik Jones and Legacy Motor Club 60 points and five playoff points each, suspended crew chief Dave Elenz two races and fined him $75,000 for the L1 violation discovered this week at the R&D Center. The team was found to have modified the greenhouse.
The penalty drops Jones from 26th to 30th in the standings heading into Sunday’s race at Sonoma Raceway.
“We have been diligently working with NASCAR regarding the penalty and are working internally to determine the course of action in response,” said Joey Cohen, vice president, race operations for Legacy MC, in a statement. “We will announce that decision within the timeframe determined by the NASCAR Rule Book.”
Cohen will serve as interim crew chief during Elenz’s suspension.
Jones’ car was among those brought to NASCAR’s R&D Center in Concord, North Carolina, after last weekend’s race at WWT Raceway.
NASCAR cited the team for violating:
Section 14.1.C: Vehicles must comply with Section 14 Vehicle and Driver Safety Specifications of the NASCAR Rule Book at all times during an Event. Failure to comply will be subject to Penalty pursuant to Section 10 Violations and Disciplinary Action.
Section 14.1.D: Except in cases explicitly permitted in the NASCAR Rules, installation of additional components, repairs, deletions, and/or modifications to Next Gen Single Source Vendor-supplied parts and/or assemblies will not be permitted.
Section 14.1.2.B: All parts and assemblies must comply with the NASCAR Engineering Change Log.
NASCAR also announced penalties Wednesday in the Craftsman Truck Series.
Crew chief Andrew Abbott has been fined $5,000, Young’s Motorsports has been penalized 25 points and Chris Hacker has been docked 25 points for a violation with the team’s window net.
Crew chief Charles Denike has been fined $2,500 for a lug nut not properly installed on Christian Eckes‘ truck for TRICON Garage.
