Numbers of note: Auto Club stats to know as NASCAR returns

0 Comments

After a two-year hiatus, NASCAR returns to Auto Club Speedway for a full slate of racing action.

Every track has its trends, but an absence from the 2021 schedule following the COVID-19 pandemic might have made it easy to forget who’s good and what’s worth remembering since Alex Bowman took the checkered flag in March 2020.

That’s where we come in. With help from Racing Insights, take a look at some of the storylines and statistics to be aware of heading into this weekend’s Xfinity and Cup series races.

Cup Series

— Stage 1 winners are a perfect 4-for-4 in winning the race at Auto Club Speedway since stage racing was introduced in 2017. That list of winners includes Kyle Larson, Martin Truex Jr., Kyle Busch and Bowman.

Austin Cindric enters Sunday’s race as the first rookie to lead the Cup points standings since 2002, when Jimmie Johnson was atop the leaderboard.

— Chevrolet leads the way with seven victories in the last 12 races in Fontana. Toyota follows up with four wins in that span. Brad Keselowski‘s 2015 triumph is Ford’s only Auto Club win since Matt Kenseth won in 2009.

— In each of the last four Fontana contests, the eventual winner led at least 54% of the race. Larson led 110 laps; Truex 125; Busch 134; and Bowman 110.

— Twenty-four of the 31 Auto Club races have been won by series champions. Bowman is the only driver without a title to win at Fontana in the last 15 races.

— The Daytona 500 marked the first race in 138 days not won by Hendrick Motorsports. Yes, the offseason factors into this stat, but Hendrick did win the final five races of 2021. The last organization to win before Team Penske’s celebration one week ago was 23XI Racing, which went to Victory Lane last October at Talladega Superspeedway with Bubba Wallace.

— Auto Club’s asphalt is the oldest on the circuit, using the original pavement laid down when the track was founded in 1996. The only track with an older surface is Dover Motor Speedway, which laid its concrete down in 1995.

— Ten different organizations finished inside the top 12 at the Daytona 500: Team Penske, 23XI Racing, Stewart-Haas Racing, Joe Gibbs Racing, Front Row Motorsports, Rick Ware Racing, RFK Racing, Hendrick Motorsports, Petty GMS Motorsports, and Kaulig Racing.

William Byron holds the longest active streak of races led at Auto Club, with laps led in each of the last three contests.

Chase Elliott boasts a series-best average finish of 9.4 at Auto Club in five starts. In 22 starts, however, Kyle Busch holds the second-best mark with a 9.59 average finish.

Xfinity Series

— There have been six different winners in the last six races at Auto Club: Kevin Harvick, Austin Dillon, Kyle Larson, Joey Logano, Cole Custer and Harrison Burton.

— Custer returns to Xfinity for the first time since Circuit of the Americas last season and only the second time since joining the Cup Series in 2020. A seven-race winner in 2019, Custer will drive the No. 07 Ford for SS Green Light Racing.

— In four of the last seven Fontana races, the pass for the win has come within the final nine laps. That includes a last-lap pass in 2016 when Dillon got by Kyle Busch, who suffered a flat tire, and Daniel Suarez, who ran out of fuel.

Noah Gragson has won three of the last 11 Xfinity races but has zero top 10s in two Auto Club starts. His best finish was 12th in 2019.

— The series has witnessed eight different winners in the past eight races dating back to last season, including first-time winners Brandon Brown, Daniel Hemric and Austin Hill.

Anthony Alfredo finished seventh a week ago at Daytona International Speedway, marking his 10th top-10 finish in 20 career Xfinity starts.

Brandon Jones has seven top 10s in his last nine races. Two years ago in Fontana, Jones won the pole and both stages, leading the opening 73 laps before contact with Hemric after a late restart relegated Jones to a 30th-place finish.

— Hemric has eight top 10s in his last 10 races and has never finished worse than 11th in three Auto Club starts.

Alex Bowman, who is last in the playoff standings, will miss Sunday’s Cup race at Talladega Superspeedway after experiencing concussion-like symptoms following his accident last weekend at Texas Motor Speedway, Hendrick Motorsports stated Thursday afternoon.

Noah Gragson will fill in for Bowman.

Bowman is the second Cup driver to miss a race because of concussion-like symptoms after a crash. Kurt Busch has not returned to racing since he crashed July 23 at Pocono. Busch said this week that he remains “hopeful” he can return this season. Six races remain in the season, including Sunday’s race at Talladega.

 

 

Dr. Diandra: How much does Talladega shake up the playoffs?

0 Comments

Talladega Superspeedway is known for shaking up the playoffs. But how well deserved is that reputation?

Playoff drivers usually view the first race in the second round of the playoffs as the best chance to earn points, earn stage points and maybe even a win given that Talladega is the second race. Now that Texas is in the rear-view mirror, let’s turn our data analysis tools to Talladega.

The shake-up index

Determining how much one race shuffles the playoffs standings requires a simple metric that is applicable to all the years NASCAR has had stages and playoffs. In a rare point of consistency, Talladega has remained the 31st race of the season since 2017, when stage racing started.

After trying a couple different approaches, I finally settled on playoff rankings. These rankings are a zero-sum game. For each driver who moves up a position, another driver must move down.

The first graph is playoff ranking as a function of race for the second playoff segment of 2021. It’s a bit of a mess, but stay with me.

A scatter graph of rank changes to help determine how much shaking-up Talladega actually does

Playoff rank runs along the left side of the graph. The highest ranked driver is at the top and the 12th ranked at the bottom.

The leftmost set of dots shows the rankings coming out of Bristol, after eliminating the lowest four drivers and re-seeding the rest. The second column of dots show the rankings after Las Vegas, which was the first race in the second round in 2021.

Each driver is represented in a different color, with lines connecting his rankings. For example, the dark purple lines show Denny Hamlin rising from third to first over these three races. The light blue lines at the bottom show Alex Bowman plummeting from seventh to 12th.

The messier the lines between two races, the more the playoffs were shaken up. Because it’s hard to quantify “messiness,” I counted each time one driver’s line crossed another driver’s line.

Each crossing indicates two drivers changed places in the rankings. The number of intersections between Bristol and Las Vegas, for example, tells you how much Las Vegas shook up the standings.

Three intersecting lines count as three shake-ups because there are three pairs of drivers crossing.

In 2021, Las Vegas had nine intersections, Talladega 13 and the Roval only five. This seems consistent with our hypothesis that Talladega is the biggest shaker-upper in the second round.

Talladega Timeline

In addition to being only one point, the 2021 Talladega contest poses another problem. Bubba Wallace won the rain-shortened race, which went 311 miles instead of the scheduled 500 miles.

That raises the possibility that 2021 might not be the most representative year for Talladega races. I therefore repeated the analysis going back to 2017. Since we didn’t have stage racing — and thus stage points — before 2017, it doesn’t make sense to compare previous years.

The table below shows the shake-up index from 2017-2021. Note that the first and third races changed from year to year.

This five years of data show that Talladega wasn’t always the race that most shook-up this round of playoffs. From 2017-19, Dover and Charlotte held that honor. That’s surprising, especially in 2017. That’s the year 26 of 40 cars failed to finish the Talladega race and NASCAR parked Jimmie Johnson and Matt DiBenedetto.

In 2020, the three races had just about equal shake-up indices.

The Roval has been the third playoff race for only two years. It was equally chaotic with Talladega in terms of affecting the standings in 2020, but less so in 2021. Kansas beat the Roval for switching up the playoff standings twice.

 A caveat for the first race

If you’re surprised to see a larger shake-up for the first race in the second round of the playoffs, you’re not alone.

The 2021 fall Las Vegas race was remarkably uneventful. There were only two DNFs, both non-playoff cars. And one single-car accident that, again, didn’t involve a playoff car. Yet it had a shake-up index of nine.

It turns out that this is a side-effect of the re-seeding protocol.

The graph below shows the same time period as the rankings graph, but reports total points for the top-12 drivers.

Immediately after re-seeding, the drivers are separated by 57 points from first to 12th. If you omit Kyle Larson’s 30-point lead, the bottom 11 drivers are separated by only 27 points.

Since a driver can earn a maximum of 60 points in a single race, the first race in a round has a lot more impact in changing the standings. In effect, the first race decompresses the re-seeding compression.

After Las Vegas, the 12 playoff drivers were separated by 78 points. After Talladega, the margin grew to 98 points.

The larger numbers for the first races in any round are more due to the re-seeding-induced points compression than to the nature of the track.

Applied to 2022

Drivers don’t have to win at Talladega. They just have to finish ahead of the other playoff drivers. In fact, if a given driver can’t win, the next best case for him is if none of the other playoff drivers win, either.

The largest drop in positions a driver has seen from Talladega is five — and that’s from the rain-shortened 2021 race. On the other hand, drivers have also seen as much as an eight-position gain in the standings following Talladega. That gain was after the 2017 race where more than half the field failed to finish, but at least one driver has come out of the fall Talladega race each of the last four years up at least three positions.

As far as the stats for this year’s second round playoffs so far: Last week’s Texas race had a shake-up index of 14. That’s higher than all but the first year of the stage-racing playoff era.

And the William Byron penalty (which Hendrick Motorsports is contesting) has a shake-up index of seven.

NASCAR weekend schedule for Talladega Superspeedway

0 Comments

The NASCAR Cup Series playoffs roll into Talladega Superspeedway, a center of uncertainty, for the second race in the Round of 12 this weekend.

Sunday’s race (2 p.m. ET, NBC) could place the first driver in the Round of 8. Any playoff driver who wins the race automatically advances to the next round.

Through the playoffs to date, playoff drivers are batting zero in the race-win category. Non-playoff drivers — Tyler Reddick, Chris Buescher, Bubba Wallace and Erik Jones — have scored wins in the first four playoff races.

Joey Logano leads the playoff points entering the race. Ross Chastain, who won at Talladega earlier this year, is second.

The four drivers below the cutline are Austin Cindric, William Byron, Christopher Bell and Alex Bowman. Byron was above the line earlier this week but was penalized 25 points for spinning Denny Hamlin under caution last Sunday at Texas Motor Speedway. That move lifted Chase Briscoe above the cutline.

Playoff races also are scheduled for the Xfinity Series (Saturday, 4 p.m. ET, USA Network) and the Camping World Truck Series (Saturday, 12:30 p.m., FS1) at Talladega.

Short-track ace Sam Ard shares Xfinity record with Noah Gragson

0 Comments

Former two-time Xfinity Series champion Sam Ard’s name returned to the forefront in the past week as Noah Gragson tied Ard’s series record for consecutive victories at four.

Although Ard has been nominated for the NASCAR Hall of Fame, his exploits generally aren’t well-known among many who follow the modern sport of stock car racing. He was on the Hall voting list for the 2023 class but was not elected.

In the 1970s and ’80s, Ard was a short-track master in the vein of stars like Jack Ingram, Harry Gant and Butch Lindley, drivers who could show up at virtually any half-mile track across the country and take home the trophy.

He won the NASCAR Late Model (now the Xfinity Series) championship in 1983 and 1984, scoring 18 wins across those two seasons. He put together four victories in a row late in the 1983 season, winning at South Boston, Virginia; Martinsville, Virginia; Rougemont, North Carolina and Charlotte.

Ard was so dominant in 1984 that he had wrapped up the seasonal championship with two races remaining. In 28 series starts that year, he had 24 top-five finishes and 26 top-10 runs. He won eight times.

In the next-to-last race of the 1984 season, at North Carolina Speedway in Rockingham, Ard suffered critical head injuries when his car slid in fluid from another vehicle and hit the track’s outside wall.

That crash effectively ended Ard’s career and impacted the rest of his life. Ard often talked of learning to walk again as part of his recovery. He said he would use a walker in a pile of sawdust in his backyard so that the landing would be softer when he fell.

Ard eventually was diagnosed with Alzheimer’s disease and Parkinson’s disease. In 2006, responding to Ard’s financial problems, drivers Kyle Busch, Kevin Harvick and Dale Earnhardt Jr., among others, launched a drive to raise funds for his family.

Ard, a native of Scranton, S.C., died in April 2017. He was 78.
