450SX Class: Foxborough Historical Facts

History Lesson: The first 450SX Class round held in Foxborough was on July 24, 1983 at Schaefer Stadium. Suzuki’s Mark Barnett waltzed into the penultimate Supercross with an 11-point lead on Honda’s David Bailey in the standings. Barnett’s transmission failed in his semi-qualifier disallowing him to compete in the LCQ per antiquated rules. Bailey scored the victory and with it a 10-point lead in the Championship. It was just enough room to win the title in the finale with Barnett coming only two points short in the final tally.

Schaefer Stadium: Schaefer Stadium also hosted Supercross in 1984 and 1990. David Bailey repeated in 1984 and Honda made it 3/3 in Foxborough thanks to JM Bayle in 1990. Supercross did not return to Schaefer Stadium before it was demolished and replaced by Gillette Stadium.

The Best a Man Can Get: Supercross returned to Foxborough after 25 years away by visiting Gillette Stadium in 2016. Ken Roczen and his Suzuki scored the late-season win, but Ryan Dungey won the Championship. Marvin Musquin won Gillette in 2018 during a Championship comeback attempt that fell short to Jason Anderson. Anderson won the most recent visit to Gillette in 2022, during his own Championship comeback that Tomac would eventually win.

Championship Percentage: 1983 is the only time the winner of Foxborough won the 450SX Class Championship. 1/3 in Schaefer Stadium and 0/3 in Gillette Stadium for 1/6 overall. 2024 will mark the seventh time the 450SX Class has visited Foxborough and fourth in Gillette Stadium.

Tom Vialle (4-3-1) lost the red plate but put in a solid runner-up ride including winning the final race of the Triple Crown. He will only be behind McAdoo by two points in Foxborough. He was making his 15th 250SX Class start and scored his fourth podium, all four of which have been in a row.

Haiden Deegan (2-1-6) had the Triple Crown lead going into the final race, but another first-turn knock-out put him on the comeback trail.

Deegan has five 250SX Class podiums in his first 15 starts.

Notes: Pierce Brown (4th; 12-4-2) Continued his consistency with another top-five finish. He has 5-5-5-4-4 finishes on the season which places him only 11 points off the red plate. Coty Schock (5th; 5-8-8) Overcame a broken collarbone in one week to nail his second-best 250SX Class finish. Schock has a puncher’s chance at the title being down -19.

250SX Class: Foxborough Historical Facts

History Lesson: The first 250SX Class race held in Foxborough was on June 2, 1990 in Schaefer Stadium. Denny Stephenson won his eighth race of the season to clinch the Eastern Regional Championship. It was the only 250SX Class race held in Schaefer Stadium.

Venue History: Schaefer Stadium’s 1983-1984 rounds pre-dated the 250SX Class, so the venue history is different than the 450SX Class. Gillette Stadium does have the same history for both classes, with rounds in ’16, ’18, and ’22. Jett Lawrence clinched the 2022 250SX Class Eastern Regional title in Gillette Stadium just like Stephenson did in Schaefer Stadium in 1990.

Only Three Left: Of the athletes in the 2022 Foxborough 250SX Class Main Event, only Pierce Brown (4th), Marshal Weltin (11th), and Hardy Munoz (22nd) are active Eastern Regional competitors lining up in the 2024 edition of Gillette Stadium 250SX Class racing.

Championship Percentage: 2/4 250SX Class winners in Foxborough have won the Eastern Regional title in the same season. 2024 will mark the fifth time of 250SX Class racing in Foxborough and fourth in Gillette Stadium.
