FOUR TEAMS SET FOR GOODYEAR TIRE TEST AT MARTINSVILLE

Four NASCAR teams will converge Tuesday and Wednesday for a Goodyear tire test at Martinsville Speedway, the lone short track left on the Sprint Cup Series schedule.

The four teams invited will help confirm the tire compound for the Oct. 30 Goody's Fast Relief 500, the seventh event in the 10-race Chase for the NASCAR Sprint Cup playoffs. Those participating at the .526-mile track are:

The Chip Ganassi Racing No. 1 Chevrolet with driver Jamie McMurray

Two tests remain on the Sprint Cup schedule for the rest of the year.

Another Goodyear tire test is scheduled at Kansas Speedway on Oct. 17, the day after the 1.5-mile track completes its second NASCAR weekend of the year. NASCAR is also scheduled to conduct an organizational test Oct. 18-19 at Homestead-Miami Speedway, site of the season finales for all three national series as part of Ford Championship Weekend.

REDDICK CAPTURES FIRST WIN OF SEASON,SHAKES UP CHASE

LAS VEGAS – Tyler Reddick outdueled Brad Keselowski Racing teammate Daniel Hemric to win Saturday night's NASCAR Camping World Truck Series DC Solar 350 at Las Vegas Motor Speedway.

The victory was Reddick's first of the 2016 season and marked the first time the Brad Keselowski Racing team had fashioned a one-two finish in the series.

Reddick led five times for 70 of the 146 laps around the 1.5-mile track, taking the advantage for the final time from Cole Custer shortly after the race's third caution.

Custer, who finished third in the No. 00 Chevrolet, faded from contention after a furious battle with Hemric, one that likely assured Reddick of the victory as the pursuers used up the grip in their tires.

Reddick's margin of victory over his teammate was 1.404 seconds as he completed the race at an average speed of 143.163 mph.

"We were spot-on from the beginning," said Reddick, who started 16th in the 31-truck field but reached the top three by the 19th lap. The victory was his third in the series and first since June 2015 at Dover International Speedway.

Ben Kennedy and William Bryan completed the top-five finishers. Christopher Bell, Johnny Sauter, Matt Crafton, pole starter Timothy Peters and Grant Enfinger were sixth through 10th.

Peters and Kennedy led the early stages of the race. Peters held the point until the 14th lap when Kennedy took over followed by Custer. The caution clock triggered the yellow flag at lap 39, giving Reddick the lead after pit service.

Reddick, Hemric and Custer exchanged the lead through most of the remainder of the event, which saw a dozen total lead changes among five drivers. Hemric led the second-most laps, 38.

Saturday night's race was the second of three in the NASCAR Camping World Truck Series Chase's Round of 8. While Reddick was not among the eight post-season qualifiers, a Hemric victory could have allowed the runner-up finisher to advance to the next round. As it is, he's 15 points outside the six-driver cutoff line heading into the Oct. 22 Talladega Superspeedway elimination race, the same as John Hunter Nemechek, who finished 16th in Las Vegas.

"Unfortunately, I was a spoiler for my teammate," Reddick said.

Hemic said it could be easy to be frustrated – so near yet so far – but noted Reddick did what he was supposed to do for the team.

"We're both racing for the win," he said. "We're doing all we can to win these races. He did everything picture-perfect."

New Hampshire winner William Byron, who's guaranteed to advance to the next round, continues as the points leader. Bell, Crafton, Kennedy, Peters and Sauter all are above the cutoff line after two of the three Round of 8 races.

KYLE BUSCH AMONG SPRINT CUP REGULARS TO MISS RESCHEDULED XFINITY RACE

The XFINITY Series Dover race postponement -- due to weather -- left teams scrambling to assemble its lineups Saturday afternoon with playoff chances on the line.

Chase for the NASCAR Sprint Cup contenders, Kyle Busch, Joey Logano and Austin Dillon were expected to perform double-duty, but with both races now on Sunday, teams had to reassemble its lineups so the trio could focus on their main event -- the first elimination race in the Chase.

Drew Herring will wheel the No. 18 Joe Gibbs Racing Toyota for Busch, while Ryan Blaney will sit behind Team Penske's No. 22 Ford for Logano and Regan Smith is set to replace Dillon in the No. 2 Richard Childress Racing Chevrolet, according to multiple reports.

Busch enters the Sprint Cup Citizen Soldier 400 (2 p.m. ET, NBCSN, PRN, SiriusXM NASCAR Radio) fourth on the Chase Grid and, just a few spots behind, sits Logano in sixth. Dillon is currently 14th, five points below the cutoff.

WEATHER CANCELS FINAL SPRINT CUP SERIES PRACTICE, POSTPONES XFINITY RACE

After spotty rain affected events all day Saturday at Dover, NASCAR postponed the XFINITY Series' Drive Sober 200 until 10 a.m. ET Sunday (CNBC, MRN, SIRIUS XM).

The second race of the NASCAR XFINITY Series Chase was set to be the capstone to a day of action at Dover International Speedway.

Saturday's on-track action started well for the second Sprint Cup practice at Dover. But sprinkles turned to heavier rain with 15 minutes left in that practice, bringing out the red flag after 45 minutes of the 55-minute session.

XFINITY Series qualifying was also off to a good start, but was scrapped after just one round, handing Erik Jones the pole position.

Final Sprint Cup practice was set for 1:30 p.m. ET (NBCSN/NBC Sports App), but was ultimately canceled due to inclement weather. 

Friday's Sprint Cup Coors Light qualifying was canceled due to persistent rain. The field was set by owner standings, allowing Brad Keselowski to start P1 for the second time this year. The Sprint Cup Series will return to the track tomorrow for the Citizen Soldier 400 at 2 p.m. ET (NBCSN/NBC Sports App).

SPRINT CUP QUALIFYING CANCELED AT DOVER;KESELOWSKI ON POLE

Friday's NASCAR Sprint Cup Series qualifying session at Dover International Speedway was canceled because of rain. The lineup was set according to the NASCAR rule book, putting Brad Keselowski on the pole for Sunday's Citizen Solider 400 (2 p.m. ET, NBCSN, MRN, SiriusXM NASCAR Radio).

Martin Truex Jr., in the No. 78 Furniture Row Racing Toyota, will start on the front row alongside the No. 2 Team Penske Ford.

"We earned it because, obviously, we've been having a great season, maybe not with what we've done on track today, but with what we've done throughout the course of the year in scoring a lot of points and winning races," Keselowski said.

"But it's certainly still something to be very proud of, to be this far into the season and be in the points lead. These are the perks you get when you're in that position. We'll take it, and of course, being up front gives us a very advantageous pit road selection for this race, which I think is very critical."

The three-round, group qualifying effort at the 1-mile concrete oval was scheduled to begin at 3:40 p.m. ET, but wet weather delayed that schedule. This marks the third straight Sprint Cup event at Dover that qualifying has been washed out by rain.

Kevin Harvick, Paul Menard, Michael Annett, AJ Allmendinger and Jeff Gordon will select Sunday's pit stalls last for receving a fourth written warning from NASCAR.

Sunday's Citizen Soldier 400 is the final event in the 10-race Chase's opening Round of 16. The results will determine which 12 drivers remain championship-eligible and which four fail to advance in the postseason.

Kyle Larson holds the final transfer spot entering the Dover race with a five-point lead over Chip Ganassi Racing with Felix Sabates teammate Jamie McMurray and Richard Childress Racing's Austin Dillon. Larson will start 12th, with McMurray and Dillon directly behind him in 13th and 14th, respectively.

The second of two NASCAR XFINITY Series practices was cut short by rain. The practice lasted about nearly half of its scheduled 85 minutes before being put on hold and eventually called due to rain.
