What won the race: Powering around Dillon McCowan out of turn four and taking the lead for good on the 21st lap, polesitter Tony Jackson Jr. of Lebanon, Mo., paced the final 10 circuits of Saturday's 30-lap March Madness finale at Springfield Raceway, securing a weekend sweep worth more than $10,000. Jackson beat McCowan to the checkers by 2.434 seconds for his 18th career Midwest LateModel Racing Association victory and second in as many nights after leading all 30 laps of Friday's $5,000 opener.

Quotable: “Jerry (Hoffman)’s racetrack, you just don’t know where to go. I was using all the lines and I knew Dillon (McCowan) had come from the back and he’s very good here,” Jackson said. “When he got by me, I just had to switch lines with him, right? He was running around the bottom, so I switched to the top and that was all she wrote.”
