Dale Earnhardt Jr. pulled off a rare feat last season when he swept the two Sprint Cup Series races at Pocono Raceway.

Prior to 2014, the last driver to win at Pocono twice in the same year was Denny Hamlin -- in his rookie season of 2006.

As June Pocono winner Martin Truex Jr. tries to join the elite club of drivers who've swept at the Pennsylvania track, what advice would Earnhardt give his good friend on making it happen in Sunday's Windows 10 400?

"He doesn't need any advice from me," NASCAR's most popular driver said of Truex. "He's pretty sharp and pretty smart and is a good talent. I don't want to help him any more than he's already going to be pretty competitive. I thought the last trip here, we had an equal car to him. The No. 4 (Kevin Harvick) was probably the best throughout most of the race. I felt pretty equal and on par with Truex. ...

"I wish Martin all the success in the world because he deserves it. He's a great guy. He's a real asset to the series and one of the good guys. You like to see those kinds of people enjoying themselves and having success. But we sure would like to get back on track and win some races ourselves."

Truex, for his part, sounds reasonably confident about returning to Victory Lane at the notoriously tricky 2.5-mile Pocono track.

Truex starts 13th, two spots ahead of Earnhardt.

"Hopefully, we can repeat on what we did last time," Truex said. "Obviously, it's not going to be easy, but I feel like we are up for the challenge."
