CONCORD, N.C. — Kyle Larson raced to his second Nationwide Series victory of the season Saturday, holding off Brad Keselowski and Kyle Busch at Charlotte Motor Speedway.

The 21-year-old Larson passed Keselowski on the 118th lap in the 200-lap race and led the rest of the way. Larson also won at Fontana.

Keselowski was second, followed by Busch, Kevin Harvick and Brian Scott.

“It was nice looking in the rear view mirror and seeing them get smaller and smaller,” Larson said. “It’s not often the 22 and 54 cars are getting smaller in your mirror.”

Busch won the previous three Nationwide Series races at Charlotte and has eight victories at the track, but wasn’t much of a factor after leading the first 23 laps.

Larson won on car owner Chip Ganassi’s 56th birthday, and one week after Jamie McMurray won the Sprint Cup All-Star race.

Sprint Cup

JEFF GORDON HAS BACK SPASM TREATMENTS: In Concord, N.C., Sprint Cup points leader Jeff Gordon cut short his practice Saturday because of back spasms and the No. 24 team has Regan Smith on standby should the four-time champion not be able to run the Coca-Cola 600.

Gordon went just 11 laps before he told his crew he couldn’t continue. He left out of a side door of his hauler and was escorted out of the track to get treatment.

Crew chief Alan Gustafson said the team would not run the car in the final practice session Saturday and instead get it ready for Sunday’s race.

Gustafson said the plan was for Gordon to start the longest event in NASCAR.

Should the pain be too much for the 42-year-old Gordon, Smith would take over the Hendrick Motorsports car.

BAYNE TO DRIVE NO. 6 FOR ROUSH-FENWAY IN 2015: In Concord, N.C., former Daytona 500 winner Trevor Bayne will race Roush-Fenway Racing’s No. 6 car fulltime in Sprint Cup next season.

Car owner Jack Roush said Saturday that he would like to field four Sprint Cup teams in 2015, but the lineup was still “in flux.” Roush did not have any updates on negotiations with Carl Edwards and Greg Biffle.

The 23-year-old Bayne had been running a part-time Sprint Cup schedule for the Wood Brothers while competing on the full Nationwide circuit for Roush-Fenway.

Roush said Bayne’s team would have fulltime sponsorship from AdvoCare, Bayne’s Nationwide backer.

Bayne won Daytona in 2011. His best showing in four Sprint Cup races this season was 19th place at Texas Motor Speedway last month.

POLICE ARREST MAN IN SHOOTING NEAR SPEEDWAY: In Indianapolis, a 19-year-old man was being held Saturday on a preliminary charge of murder in the early-morning shooting death of a race fan in a parking lot near the Indianapolis Motor Speedway.

Avory Johnson of Indianapolis was arrested in the death of 25-year-old Max Levine of Kokomo, Speedway Police Lt. Trent Theobald said in a news release.

Marion County Jail spokesman Julio Fernandez said that Johnson is being held without bond on a charge of murder.

Theobald said that Levine was shot in Coke Lot 1 about 2 a.m. An argument preceded the shooting, Theobald told The Indianapolis Star.

The Coke Lot is a popular spot across the street from the speedway, where Indy 500 race fans have set up tents and partied on race weekend for decades.

Indiana State Police Sgt. Brian Olehy said the race weekend incident is unusual, but it isn’t the first shooting. In 2012, a fan was hospitalized after he was shot in the chest after an apparent altercation across from the speedway.

ROSBERG TAKES POLE POSITION FOR MONACO GP: In Monaco, Nico Rosberg won the pole position for the Monaco Grand Prix ahead of his Mercedes teammate Lewis Hamilton and Red Bull’s Daniel Ricciardo.

Hamilton has won the past four races and leads the overall standings by three points from Rosberg, who won the season opener in Australia, where Hamilton retired with engine failure.

The Mercedes pair went out for one final lap Saturday with less than a minute remaining. Rosberg lost control coming out of the Mirabeau turn and slid down an escape road.

A yellow flag came up, meaning that Hamilton could not improve on his time and Rosberg clinched his second pole of the season. Hamilton has the other four.

Four-time defending champion Sebastian Vettel of Germany finished fourth, while Fernando Alonso of Ferrari was fifth.
