SCARBOROUGH — Bradley Babb returned to his home track Saturday night to claim his second American Canadian Tour victory of the season.

Babb fought off a late challenge from Wayne Helliwell Jr. of Dover, New Hampshire, in the 150-lap race for Late Model Sportsman division cars at Beech Ridge Motor Speedway.

Babb, 22, took the lead away from Travis Stearns of Auburn with a crossover move down the frontstretch on Lap 61. Stearns, who led for the first 60 laps after starting from the pole, forced Babb to run on the outside groove for 17 laps before the young Windham driver could close down to the inside groove.

Babb picked up $2,500 for the win, while Helliwell, who won ACT titles in 2012 and 2013, earned $1,500 for his second-place finish.

Babb, who moved into second place on Lap 35 after starting on the outside of the third row, held the lead for 79 laps before temporarily losing it to Helliwell.

After taking the lead from Stearns, Babb was able to put some lapped cars between himself and his pursuers.

Helliwell, though, moved into the lead coming off Turn 2 following a restart on Lap 143. He kept Babb, a former Beech Ridge champion, on the outside for nearly five laps before Babb regained the lead.

Eddie MacDonald of Rowley, Massachusetts, worked his way up to finish third after starting on the outside of row 22.

Stearns finished fourth and Rowland Robinson of Steuben was fifth.

Stearns turned in the fastest lap time during 30 minutes of practice. On his 13th lap, with several other cars on the track, he covered the three-eighths of a mile oval in 15.731 seconds. Stearns carried his speed into the third qualifying heat, finishing third to earn his spot on the pole after starting eighth among the 10 cars in his heat.

Robinson earned the other spot on the front row, passing five cars during the third qualifying heat after starting in the ninth spot.

Nick Sweet, last year’s winner from Barre, Vermont, did not run Saturday. Early Saturday morning, his wife, Kristin, delivered the couple’s third child, a son named Benjamin.

Jacob Dorr of Sanford picked up his second win of the season in the collision-filled 40-lap Pro Series feature, the track’s top racing division. Mike Fowler of Scarborough finished second. Reid Lanpher, the 17-year-old defending division champion from Manchester, was 17th among the 19 cars in the race and fell out of the points lead.

Frank Wear of Buxton won the 35-lap Sport Series feature. Craig Smith of East Waterboro finished a close second to add to his points lead.
