BUBBA WALLACE FAST AT ELDORA

Rookie goes to top of leaderboard early and stays there

ROSSBURG, Ohio -- Rookie Darrell Wallace Jr. vaulted to the top of the leaderboard early and stayed there, leading final practice Wednesday for the NASCAR Camping World Truck Series at Eldora Speedway .

Wallace, driving the No. 54 Toyota from Kyle Busch Motorsports, turned a fast lap of 89.820 mph around the half-mile dirt track as the series made final preparations for Wednesday nights inaugural Mudsummer Classic (qualifying races, 7 p.m. ET; main event, 9:35 p.m. ET, both on SPEED).

Townley's teammate German Quiroga Jr. was fourth-best as Toyotas swept the top four slots on the practice sheet. Defending series champion James Buescher completed the top five in a Turner Scott Motorsports Chevrolet.

Dirt late model star Scott Bloomquist was sixth-fastest in another Kyle Busch Motorsports Toyota.

Contact with the right-rear fender and the outside retaining wall was commonplace Wednesday as drivers slipped, slid and searched for grip and momentum in the high groove, hanging out their rear bumpers in the process. Among those slapping the wall were Hines, Dave Blaney and Kyle Larson . Max Gresham also slowed with a solo spin in Turn 2 midway through the final 90-minute session.
