Two fill-in drivers have been confirmed for the IMSA WeatherTech SportsCar Championship’s next race at Circuit of The Americas, on May 6.
Wolf Henzler will deputize for Kevin Estre in the No. 912 Porsche GT Team Porsche 911 RSR, while Marco Bonanomi will make his IMSA Prototype class debut as a fill-in driver for Tom Kimber-Smith in the No. 52 PR1/Mathiasen Motorsports Ligier JS P217 Gibson.
Henzler will be in the No. 912 car alongside Laurens Vanthoor in GT Le Mans in the first “standard” two-hour, 40-minute race of the season, the Advance Auto Parts Showdown, as Estre will be on FIA World Endurance Championship duty the same day in the WEC 6 Hours of Spa-Francorchamps with Porsche’s GT Team there.
Henzler’s absence means if TRG runs its Porsche 911 GT3 R at COTA in the GT Daytona class, Kevin Buckler would need a replacement for him.
There’s another potential fill-in-for-WEC driver scenario needed if Alegra Motorsports, the Rolex 24 at Daytona winners, were to run in GTD as well. Thus far Carlos de Quesada’s team has run Daniel Morad and Porsche factory driver Michael Christensen in its No. 28 Porsche in GTD through three races, but with Christensen and Estre set to share the No. 92 car at Spa, a replacement would need to be sourced there.
Bonanomi is the second replacement that is confirmed though. The Italian, who made one prior IMSA start since the 2014 merger with Fall-Line Motorsports in an Audi R8 LMS Ultra, will fill-in for “TKS,” who returns to England to take care of his mother, who is battling cancer.
“Tom will unfortunately miss the next race at Circuit of the Americas. He needs to be able to spend time back in the UK with his mother who is presently undergoing treatment for cancer,” said team principal Bobby Oergel.
“As all the drivers who have driven with PR1/Mathiasen Motorsports know, once you’re a part of our team, you’re family, and Tom is a big part of this family. It’s unfortunate that he will miss a round of the championship, but we know that family comes before racing, and we’re happy that he is able to take the time he needs to be with his family during this time.”
“Our thoughts and prayers are with Tom and his mother, and we are praying that she will be cancer free in the near future.”
Bonanomi has tested with the car and will share the car with Jose Gutierrez, who missed Long Beach as Will Owen filled in for him there.
“I was very happy to receive the call from PR1 to drive at their test at COTA. It was my first time driving the Ligier, but I think the test was very positive,” said Bonanomi.
“We tested some set up changes for the race that I think will be very good. The track itself is very demanding on the car and tires, especially with the extreme temperatures that can be present. The first practices during race week will be very critical to get everything just right in terms of set up, but after the test, I think we should be pretty close.”
For the fifth time in 10 rounds of the 2023 Monster Energy Supercross season, the three riders at the top of the championship standings shared a podium and while those points tell one story, the NBC SuperMotocross Power Rankings after Detroit tell a slightly different tale.
Chase Sexton has been all but perfect during the past 45 days with podium finishes in each of his heats and Triple Crown features. His only stumble during this period was a 10th-place finish in the Indianapolis Main. Last week, Sexton was perfect with wins in both his heat and the feature, although he needed a little help from an Aaron Plessinger mistake to take the top spot on the podium at the end of the night.
Cooper Webb finished fifth at Houston and was beginning to worry ever so slightly about his position in the points. Prior to the race in Tampa, he told NBC Sports that it was time to win and like Babe Ruth pointing to the outfield fence, Webb went out and captured it. Following that race, Webb has swept the podium and earned the red plate two weeks ago in Indianapolis. At Detroit, he added two more points on Eli Tomac as the season begins to wind down.
Tomac struggled with a stiff neck at Indianapolis and after a modest third-place showing in Detroit, he revealed he was still suffering a little. Webb and Sexton have been able to close the gap on Tomac in the past 45 days, but one of the main reasons he is so close in the points was a pair of wins that started the year. Seattle is going to be important for the defending champion because Tomac cannot afford to lose any more momentum with seven rounds remaining.
It appeared Jason Anderson was turning things around. He earned his fifth heat win at Detroit, which was also his sixth consecutive race (including features) in which he scored a top-five. A fall in the Detroit Main dropped him a lap off the pace and sent him home with a season-worst finish of ninth, causing a ripple effect in the SuperMotocross Power Rankings.
Justin Barcia was a huge part of the show last week in Detroit. He swapped positions with both Webb and Tomac in the middle stage of the race, which allowed Sexton to close the gap. Barcia finished fourth in that race to earn his third consecutive top-five. He’s been outside the top 10 only once in the first 10 rounds.
Adam Cianciarulo had a great start to the Main. He led a couple of laps before losing a lap and slipping back to eighth in the final rundown. That run was strong enough to elevate him three positions in the SuperMotocross Power Rankings after Detroit.
The NBC SuperMotocross Power Rankings look at the past 90 days in the 250 class in order to have a balanced comparison between the East and West divisions and Hunter Lawrence has been all but perfect this year. At Detroit, he earned his fifth win of the season and kept alive a streak of podium finishes in six rounds. He tied his brother Jett Lawrence with 10 250 wins one week before the West riders take to the track for back-to-back races at Seattle, Washington and Glendale, Arizona.
The Lawrence brothers are dominating the points in each of their respective divisions, which means the remainder of the field is battling to be best in class.
In the East, that rider is Nate Thrasher, who beat Hunter in a head-to-head matchup in their heat only to finish second in the main when the majority of points were awarded. Thrasher seems to have accepted his position in the championship standings, but that doesn’t mean he won’t keep trying for wins.
Haiden Deegan showed a lot of aggression in his heat last week. He threw a couple of block passes at his teammate Jordon Smith and set up a series of events that kept Smith from making the big show while Deegan settled into second in the preliminary. Deegan was unconcerned about how he raced his teammate and would not let a little controversy keep him from celebrating his second career podium in Detroit.
Jeremy Martin just keeps clicking off solid results. He won his heat last week by making a pass on Deegan and Smith while they were in the heat of their battle. Martin finished fourth in the Main, which means he continues to have only one finish worse than sixth in any of the features or mains.
Smith fell one position in the points standings, but the damage was even worse in SuperMotocross Power Rankings after Detroit. Crash damage in his heat contributed to a last-place finish in that race, for which he earned minimal points. He was not able to advance from the Last Chance Qualifier after stalling his bike in heavy traffic.

* The NBC Power Rankings assign 100 points to a Main event winner and 90 points for each Heat and Triple Crown win, (Triple Crown wins are included with heat wins below the rider’s name). The points decrement by a percentage equal to the number of riders in the field until the last place rider in each event receives five points. The Power Ranking is the average of these percentage points over the past 45 days for the 450 class and last 90 days for 250s (because of the split nature of their season).
