There aren’t many constants in NASCAR. A driver can visit Victory Lane one week and go winless for another two years. A competitor can lead 99 percent of the laps in a race and still lose.

There has been one constant the last couple years on the NASCAR national series circuit – William Byron piling up wins.

The 19-year-old Charlotte native, who amassed a Sunoco Rookie-record seven wins in the NASCAR Camping World Truck Series last season, has taken the checkered flag in three of the last five NASCAR XFINITY Series events. He’s also been the highest-finishing full-time XFINITY Series driver in the last six races.

After visiting Victory Lane at Indy last Saturday, Byron will go for his second consecutive triumph in Saturday’s US Cellular 250 – the place where he kicked off his run of wins in June.

He’ll try to join Ricky Stenhouse Jr. (2011) as the only driver to sweep the season’s races in The Hawkeye State.

“Every time I go to Iowa Speedway, I feel like there are always guys that are better than me,” Byron said. “By the end of the race though, I feel like our team gets there. The last 50 laps we are really there and we have a pretty good shot at the win. This time around it is going to take more of the same and it is going to take an even-keeled mindset to win this race.”

Watch the NASCAR XFINITY Series race the US Cellular 250 at Iowa Speedway at 3:30 pm ET on NBC.
