  Mintz opens Attica season with last lap, last corner All Star win; Schlenk earns 36th career late model victory

  ATTICA, Ohio - Gibsonburg, Ohio's Craig Mintz executed a last lap last corner pass to score his second career Tezos All Star Circuit of Champions victory to open Attica Raceway Park's 2023 season and the Core and Main Spring Nationals presented by Construction Equipment and Supply, Advanced Drainage Systems, Erie Blacktop, and Smith Paving. It was the 137th appearance of Tony Stewart's All Stars at "Ohio's Finest Racing" speed plant. Mintz was running fourth when the caution flew with 10 laps to go. The former Attica track champion used the yellow to cool his tires and it paid off. He moved into third on lap 28 and took second with six laps to go and quickly closed on leader Zeb Wise. Entering the final two turns, Mintz drove to the outside of Wise and the drag race to the checkers saw Mintz win by .074 seconds. It was his 16th career win at Attica and his first All Star win since April of 2012. "We've been struggling with bleeders all night. Just couldn't get going on those long runs. During that caution I was actually trying to cool my tires down. I knew we had a great car and I probably showed my hand a little early. It's fun to race with Zeb (Wise). We were both really going for it…you could probably measure that win in millimeters," Mintz said beside his Real Geese Decoys, Modern Woodman of America, KS Sales and Service, NAPA of Fremont backed #09. "This means so much. My dad, the guys behind me, my wife, my kids…they all bust their butts to give me the chance to race. We're out here doing it for fun," Mintz added. "That was frustrating," said Wise beside his Rayce Rudeen Foundation, Sundollar Restoration, Hager Realty backed #26. "Hats off to Craig. He drove one heck of a race. I feel like I let my team down there. I really didn't know where to go in turns one and two." "Last week we won with a last lap pass (at Williams Grove Speedway) and tonight we got beat by one. Hopefully tomorrow we can finish it with a win," added Wise who led laps 28 through 34. Sikeston, Missouri's Hunter Schuerenberg led the first 27 laps and held on to finish third, followed by Brent Marks and Parker Price-Miller. "You are almost a sitting duck on a restart like that. You don't know if you should stay where you have been running or try a different line and you don't know what line the guys behind you are running. It didn't work out for us tonight but we finally put a whole night together. We've been fast all year but just haven't had the results so this is a big step forward," said Schuerenberg of his TK Concrete, Maxim Trucking, Logan Contractor Supply, Eddie Gilstrap Motors backed #55. Despite losing his brakes half way through the Dirt Nerds Podcast, Propane.com UMP Late Model A-main, McClure, Ohio's Rusty Schlenk took the lead from Ryan Missler on lap 18 and drove to his 36th career victory at Attica. "Normally I run the cushion but it wasn't there tonight so I had to go to the bottom. I almost forgot how to run down there. After the start of the season we've had from engine and transmission issues to problems with the truck and trailer….this is a huge shot in the arm," said McClure beside his Velocita Firesuits, Buckeye Concrete Coatings, Terry Henricks Chrysler; Tom Finch Auto, VP Fuel, Dominator Race Products, Forbes Construction, All Star Performance, Mullins Engines, Willy's Carbs backed #91. Missler jumped out to the early lead in the late model feature as Schlenk, Nathan Loney, Doug Drown and Eric Spangler battled for second. Schlenk drove from third to the lead on lap 18 and after a spirited battle with Missler, pulled away for the win. Spangler, Drown, Loney and Missler rounded out the top five. Attica Raceway Park will wrap up the Core & Main Spring Nationals Saturday, April 15 with the 305 sprints joining the All Stars.
