Defending series champ Adam Florian moved out front on lap 22 and rolled to the win in the 50-lap Top Dog shootout, the featured event of Saturday evening’s Structural Mechanical 200 for the Arena Racing Hampton Roads Pro Series at Hampton Coliseum.

The victory was the third Top Dog win for the Nansemond-Suffolk Academy student and his sixth win overall this season.

C Main winner Chris Crecelius drew the pole for the start of the event, sharing the front row with Charlie Green, last week’s Top Dog victor.

By lap 10, Green led by four lengths over Nelson Moody, who faced a challenge from Florian.

Florian captured second on a restart a few laps later. Scott Prillaman, also of Suffolk, moved up to third a couple laps later on lap 17.

After shadowing Green for several circuits, Florian pushed his machine to the point on lap 22. He ducked under Green off Turn 2 and completed the pass through Turns 3 and 4.

By lap 30, Florian’s advantage had swelled to three lengths, while Prillaman and Derek Miller had pulled to within a car-length of Green.

The last of the race’s three yellow flags flew on lap 36 when Chris Raiford spun in Turn 2.

The green flag went back in the air as the field completed lap 41. Florian immediately cleared Green, who suddenly found Prillaman to his inside. Caught to the outside, Green tumbled down the running order, giving way to Prillaman, Travis Wall and Miller.

Florian motored to a half-straightaway advantage — a margin he kept to the finish. Prillaman was second, while Wall, Miller and Green completed the top five.

After seeing his points lead shrink in recent weeks, Scott Prillaman righted the ship in Saturday’s 50-lap A Main. Starting third, he moved out front on lap 5, then held off Derek Miller down the stretch to collect his fourth feature win of the season.

Robbie Davis drew the pole and paced the first four circuits. Prillaman moved up to second on the start and ducked under Davis on lap 3. Davis fended off Prillaman’s bid until lap 5 when Prillaman eased out front.

The third, and final, yellow flag was displayed on lap 40. Under green for the last time, Prillaman eked out a half-length margin over Miller. By the finish, his winning margin had grown to three lengths. Miller was second, followed by Nelson Moody, Jordan Wood, Adam Florian and Travis Wall. The top six finishers moved on to the Top Dog race.

Escaping the big snowfall in Maryland, Michael Weddell marked his return to action with a dominating pole-to-checkers run in the 50-lap B Main. The win was his third of the season.

Weddell grabbed the lead on the first lap, pulling ahead of Chris Raiford, who dropped back into the runner-up spot.

Weddell and Raiford remained the top two drivers even through three caution restarts.

Charlie Green closed in on Raiford’s bumper and took second place on lap 38. The exchange allowed Weddell to extend his margin to five lengths.

Over the closing circuits, Green nibbled away at Weddell’s advantage. He ran out of laps, though, and Weddell won by three lengths.

Chris Crecelius started on the pole and led all the way for his first win of the season in the 50-lap C Main.

The last of the race’s four caution flags waved on lap 49 when Landon Florian spun in Turn 2, while battling Craig Carlton for fourth.

Under green for the final time, Crecelius eked out a slim margin over Aaron Leach and drove on to a one-length victory.

Connor Hall emerged from a tangle with pole starter Cullen Roberts to notch his fourth straight victory in the Youth Series feature.

Roberts took the lead in Turn 2 on the opening lap, pulling ahead of Hall. On lap 17, the lead duo locked horns off the second corner and Roberts ended up planted against the backstretch wall.

Back under green, Hall cruised on to the win. Patrick Groff was second.
