In the first 20-lap Twin A-Main in the Winged Super Modifieds, Scott Mohs of Plymouth jumped into the early lead with Jeremy Mullenbach and Butch Hafemann of Campbellsport on his bumper. By the fourth lap, six-time feature winner Paul Pokorski of West Bend charged into second and began reeling leader Mohs in. Two laps later, Pokorski tucked his car to the inside of the leader to cross the line with Mohs still in the lead by just a couple inches. Mohs and Pokorski charged around the Manitowoc track side by side with Pokorski changing grooves to pass Mohs on the outside to take over the lead in lap seven. In the same lap, last years track champion Tim McMullen of Plymouth charged into third behind the battling duo. As leader Pokorski began lapping cars at the mid-point of the race, McMullen passed Mohs to take up the challenge spot. Pokorski and McMullen weaved their cars through the lapped traffic but time was not on McMullen’s side. Pokorski charged through the checkered to win the first half of the Modified Twin Challenge. McMullen followed in second with Brad Swendrowski of Milwaukee making a last lap pass to finish third. Mohs and Kris Hansen of Manitowoc rounded out the top five.

With the lead lap cars from the first race inverted in the line-up for the second race, Jeremy Mullenbach charged in the lead with Pokorski on his trail from the first lap. Hansen and McMullen battled behind them for third. Pokorski threw his car to the outside of the track to take over the lead in lap three as McMullen tucked to the inside of Hansen to beat him across the line by inches to take over third. A lap later, McMullen passed Mullenbach to take over second with some track to make up to catch leader Pokorski. A couple yellow flags pulled the field back together in laps eight and nine but Pokorski charged out on the green flag. McMullen running the inside groove changed to the outside as Hafemann challenged him on the high groove from third. Chuck Tuschl of Reedsville moved into fourth with Hansen charging after him. As the field charged through the turns, the Modified competitors raced three wide through turns one and two and down the backstretch. Pokorski again began lapping traffic with McMullen and Hafemann battling behind him. At the checkered flag, Pokorski won the second leg of the Twins earning him the overall win for the race. In this race, McMullen followed in second with Hafemann, Hansen and Tuschl completing the top five. Following Pokorski in the overall win, McMullen finished second with Hansen, Mohs and Swendrowski rounding out the top five.

In the Limited Late Model A-Main, Dave Schaetzer of Sheboygan jumped into the early lead with Dave Haag of Glenbeulah charging after him. Scott Haugstad of Plymouth moved into third by the second lap with Paul Dingel of Sheboygan on his bumper. By lap six, a three-car battle for third developed with Haugstad charging the high side of the track, Dingel on the inside and point leader Dan Dippel of Plymouth sticking to their bumpers for his opportunity to advance. A lap later, Haugstad only held third by inches as he and Dingel charged side by side around the track. Another lap was completed with Dingel moving into third just before a yellow flag stopped the hard-charging action and relined up the field. When the green flag flew, Schaetzer charged out in front with Haag on his bumper and Haugstad moving back into third. Dippel charged passed Dingel on the front stretch to take over fourth in lap nine. In the next lap, Dippel threw his car to the outside of Haugstad to challenge for third. By this time, the top five cars were tightly packed in the front and Dippel used the outside of the track to pass Haugstad on the backstretch but Haugstad battled back through turns three and four. When Dippel and Haugstad charged down the front stretch, the two crossed the line almost even with Dippel having the slight advantage. Haag attempted to tuck his car inside leader Schaetzer but Schaetzer closed the door and maintained his lead. Dippel again used the high groove to pass both Haag and Schaetzer to take over the lead with four laps to the end. Schaetzer kept his car tight on the low side of the track and took back the lead in lap 13. Dippel battled back and retook the top spot a lap later. At the checkered flag, Dippel won his tenth A-Main of the season. Heat winner Haugstad passed on the white flag lap to finish second with Dingel, Haag and Schaetzer rounding out the top five.

An early red flag for a flipped car and hard-charging racing action highlighted the Grand National A-Main with the race stopping only in lap three when Bob Cullen of Chilton flipped his car for the second time this season. As Cullen’s car rolled front corner to rear corner in front of gasping fans who were able to see the entire undercarriage of the Grand National, safety crews reached Cullen as he was able to exit the car under his own power. The crash sent Cullen and another competitor to the pits not to return to the race. As the feature was restarted, a hard-fought battle for the lead developed with five-time feature winner Mike Bastian of Manitowoc and Tim Thompson of Campbellsport raced side by side through the turns and down the straightaways. Brett Wenzel of Two Rivers, Ben Schmidt of Plymouth and last week’s feature winner Bob Peter of Howards Grove charged behind them to chase down the leader. With Bastian and Thompson separated by only inches for the lead at the line in lap five, Scott Sohrweide of Chilton moved into fifth place. Thompson used the inside groove to pass for the lead a lap later with Bastian hot on his tail. Wenzel and Schmidt charged after the battling dup with Brian Gilles of Plymouth pulling next to Sohrweide to challenge for fifth.

An incident on the backstretch between leader Thompson and Bastian sent Thompson spinning into the infield and sent both drivers to the pit area a lap later not to return. After the top two left, Wenzel charged out in front with Sohrweide throwing his car to the outside to take over second and Schmidt following in third. Side by side the top competitors charged around the track with Sohrweide racing outside Wenzel to take over the lead in lap ten. With half the race to go, the top five, Sohrweide, Wenzel, Schmidt, Gilles and Peter, charged tightly packed together three abreast to battle for the win. In lap twelve, Gilles slid inside passed Schmidt to take over third by inches but Schmidt, charging on the high side, raced passed Gilles the next lap to secure third again.
