Eastbourne Eagles made it five home wins from five, despite seeing Jason Crump claim their long-standing track record.
The Belle Vue star took heat one on a heavily sawdusted Arlington circuit in 54.9 seconds but could not prevent Eagles winning 50-40 in their table-topping Elite League clash.
Crump became the first man to ever go under 55 seconds at the East Sussex track as he eclipsed the previous best of 55.1sec set by Tony Rickardsson almost five years ago.

Fit-again Scott Nicholls ended the Aussie star's hopes of a five-ride maximum by beating him in a thrilling heat 15.
Nicholls scored paid 13 from five outings with Crump the only visitor to beat him.
Edward Kennett was paid for 11 from five and Lee Richardson scored 11 from four with Crump the only man to beat him.
