The four-night Memorial Day Weekend for the Summit USMTS National Championship presented by RacinDirt wrapped up Monday at the Mason City Motor Speedway with points leader Dustin Sorensen dominating the 8th Annual Double Down Showdown.

The win, worth $5,000, was the third of the 2022 campaign for the 21-year-old top gun from Rochester, Minn., and ninth of his short career. That moved him into a tie with Brad Waits for 23rd on the all-time USMTS wins list.

After earning the Sybesma Graphics Pole Award, Sorensen set sail and let his followers battle back and forth for second-place money. A pair of early cautions and some late-race traffic issues allowed defending USMTS National Champion Dereck Ramirez to narrow the gap, but once in the clear Sorensen pulled away again to an eight-car-length victory.

Ramirez, who started ninth on the 23-car grid, settled for second with Zack VanderBeek, Cayden Carter and FK Rod Ends Hard Charger Award winner Tanner Mullens following him to the checkered flag.

Dan Ebert fought hard for a sixth-place paycheck, Rodney Sanders secured the seventh spot, Jake Timm took eighth, Jason Hughes nabbed ninth and Terry Phillips climbed six positions to round out the top 10.

Ramirez and Mullens are both two-time winners at the North Iowa Fairgrounds Action Track. With his effort, Sorensen joined Hughes, Sanders, Phillips and Lucas Schott with one win apiece.

No rest for the wicked: Three days from now on Thursday, June 2, the 3rd Annual Wehrs Machine Bullring Bash—twice voted as the USMTS Race of the Year—takes place at the Dallas County Speedway in Urbana, Mo., where the previous two feature races were decided in the final corner on the final lap.

The following night, drivers will cross the border into Kansas to hunt a top prize of $20,002 to win and a minimum $1,002 to start at the 6th Annual Grant Junghans Memorial on Friday, June 3, at the legendary Lakeside Speedway in Kansas City.

Back on the other side of the border, the tripleheader kickoff to an unbelievable month of June events concludes Saturday, June 4 with the inaugural Bushwhacker presented by RacinDirt at the all-new spectacular I-70 Speedway in Odessa, Mo.
