RAIN INTERRUPTS POCONO XFINITY SERIES RACE

Caution came out for rain at Pocono Raceway Saturday on Lap 52 of the scheduled 100 laps in the Pocono Green 250 NASCAR XFINITY Series race.

Kyle Larson was leading at the time of the caution in the No. 42 Chip Ganassi Racing Chevrolet. The race was red-flagged at Lap 54.

NASCAR was drying the track in an effort to get the race back underway. Since the race passed its midway point, it would be considered official should it get called.

Pocono Raceway does not have lights so darkness could become a factor. Sunset is expected at 8:30 p.m. ET.

Rain is also in the forecast for Sunday's NASCAR Sprint Cup Series Race, the Axalta 'We Paint Winners' 400 (1 p.m. ET, FS1, MRN, SiriusXM NASCAR Radio.)

SPRINT CUP SERIES: DRIVE LIKE A BUTTERFLY: NASCAR AND MUHAMMAD ALI

RELATED: Drivers pay respects to Ali

Boxing and cultural icon Muhammad Ali, who passed away Friday at age 74, has a direct connection to NASCAR -- specifically, to Hall of Famer Bill Elliott.

Yes, "The Greatest" and "Awesome Bill" have a history that dates back to 2001 when Elliott sported a likeness of Ali on his No. 9 Dodge while driving for Ray Evernham.

The special paint scheme was revealed at historic Bristol Motor Speedway, and then run June 10, 2001, at Michigan International Speedway. Ali lived in Michigan at the time.

The scheme partnered Ali and NASCAR in a promotion of the Special Olympics, and also to support a new diversity scholarship program that Dodge had implemented and NASCAR was supporting.

Ali thrilled drivers that day when he unexpectedly walked into the drivers' meeting and earned a standing ovation.

"If I had a fast car, I'd be out there racing against you," Ali said, according to a 2001 report in the Daily Press (Virginia) newspaper. The legendary boxer later gave the command to start the race.

The partnership certainly left a mark on Chase Elliott who, like Ali's daughter Laila, followed in his father's footsteps.

After 13 races, Elliott weighs in on rookie season

LONG POND, Pa. -- This weekend, Chase Elliott will tackle the "Tricky Triangle" for the first time in a NASCAR Sprint Cup Series car.

Elliott has had a strong start to his rookie season, already logging four top-five finishes and nine top-10s within the first 13 races of the year. Among active drivers, his nine top-10 finishes are tied with teammate Jimmie Johnson for the most top-10 finishes through the first 13 races of a rookie season.

Currently eighth in the season point standings, Elliott feels as though he is in a "decent" spot, with some weekends having been better than others.

"The way I see it is yes, you can ‘points’ your way in," Elliott said of making the Chase for the NASCAR Sprint Cup. "But to have a shot you’ve got to be a consistent contender to win races. And I think we have a little bit of work to do to be among those consistent contenders that have the ability each week and those are the guys you’re going to have to beat when it comes this fall."

Elliott has run consistent top-10s in the last four events, including at Talladega, where he claimed his second pole position of the year. His career-best finish was third place at Dover International Speedway.

The 20-year-old rookie said he knows he as the team behind him to remain a solid, competitive force throughout the season. Perhaps even a force competitive enough to land that first victory.

"I feel like I have a team and a group of guys that are capable of winning if I do my part for them," Elliott said. "I truly believe that. I think that’s something that’s important for all of us to believe. And if we didn’t believe that, we might as well stay home. That’s the mindset we have coming into each race weekend, regardless of where it is."

This weekend at Pocono, Elliott will look to land his No. 24 NAPA AUTO PARTS Chevrolet SS in Victory Lane.

"We’re going to give it our best effort to do that and if we do, great," he said. "If we don’t, it sure won’t be for a lack of effort.”

Chase Elliott’s fast Sprint Cup start compares favorably to what current drivers did

As rookie Chase Elliott prepares for this weekend’s race at Pocono Raceway, it marks a key milestone in his young career.

This will be his 19th career Sprint Cup race. Thus, he’s run in what would be equal to half a season.

When compared to the first 18 races of some drivers, Elliott matches well in regards to top-five and top-10 finishes.

Elliott, who ran five races last season, has nine top-10 finishes in his first 18 starts. Among current drivers, only Jimmie Johnson and Tony Stewart had more top-10 finishes at this point than Elliott did with 10 each.

Elliott has four top-five finishes at this point. Among active drivers, only Kasey Kahne had more top fives in his first 18 races with five. Also, former driver Jeff Gordon had five top-five finishes and eight top 10s in his first 18 career Cup races.

“I feel like I have a team and a group of guys that are capable of winning if I do my part for them,” Elliott said Friday at Pocono Raceway.

Here’s how Elliott’s record in his first 18 races compares to those among current drivers in their first 18 Cup races.

Five drivers to watch at Pocono

Here’s who you should keep an eye on this weekend with the Sprint Cup Series at Pocono Raceway:

Dale Earnhardt Jr.

After back-to-back runner-up finishes at Texas and Bristol in April, Earnhardt has failed to post a top 10 in the last five races. But he’s been stout in recent years at Pocono where’s he collected two wins, five top fives, and eight top 10s since 2011 (10 races). The “Tricky Triangle” is a good place for him and the No. 88 team to get things together.

Martin Truex Jr.

The Coca-Cola 600 winner heads to Pocono to defend his win last spring. He threatened to sweep when the series returned to Pocono later in August, but was one of several front-runners that ran out of fuel in the closing laps (he wound up 19th). Considering how fast he and his Joe Gibbs Racing “partners” have been everywhere, expect Truex to contend this weekend at one of NASCAR’s big horsepower tracks.

Kyle Larson

Pocono is another place where Larson is steady. He’s posted a 9.0 average finish in his first four starts, including finishes of eighth and 12th in the 2015 races. If his recent surge in performance continues, he can contend again for his potential first career Sprint Cup win — or at least a strong finish to cut into his playoff deficit (-38 points behind 16th place).

Jimmie Johnson

Johnson has had a solid record of late at Pocono. Since 2011, he’s posted a 9.4 average finish (including a win in Spring 2013) there, while also leading the series in laps led (221). He’s also gained the second-most points among active drivers at Pocono during that span (356), trailing only Dale Earnhardt Jr. (371)

Kevin Harvick

Before his engine failed early last August, Harvick had finished runner-up in the previous two Pocono races. The 2.5-mile track is one of four on the current Cup schedule where he’s yet to win (the others being Texas, Kentucky, and Sonoma). But in the midst of another stellar season, he can definitely check this one off the list on Sunday.
