Comparing William Byron’s fast start to other XFINITY Series stars

Rookie William Byron is off to a fast start in the NASCAR XFINITY Series. Following his win on Saturday at Indianapolis, Byron already has three victories in his first 18 starts in the series. Let's see how that compares to the top five winners in XFINITY Series history -- Kyle Busch (89 wins), Mark Martin (49), Kevin Harvick (46), Carl Edwards (38) and Brad Keselowski (35).

First, let's start with Byron's stats in his first 18 starts, which are impressive: At age 19, he has three wins, seven top fives and 12 top 10s and has led 160 laps for JR Motorsports. Byron's wins have come at Iowa, Daytona and Indianapolis (pictured).

Kyle Busch was the same age as Byron, 19, when he reached 18 starts in XFINITY. He had one win, seven top fives, 11 top 10s and 471 laps led for Hendrick Motorsports. Busch got four more wins in his age-19 season (2004) after his 18th start. Pictured: Busch's 2007 win at Daytona.

Mark Martin was 28 when he reached his 18th start in the XFINITY Series. He had two wins, three top fives, nine top 10s and 203 laps led for owners Ed Whitaker (1 start) and Bruce Lawmaster (17 starts). Pictured: Martin in Jack Roush's No. 60 in 1997 at Daytona.

Kevin Harvick was 24 when he reached his 18th start in the XFINITY Series. He had zero wins, five top fives, nine top 10s and 225 laps led for Richard Childress Racing. Pictured: Harvick after his 2005 victory at Texas.

Carl Edwards was 25 when he crossed the 18-start barrier. By then, he had three wins, six top fives, 11 top 10s and 359 laps led for owners Fred Bickford (1 start), Bobby Benton (1 start) and Jack Roush (16 starts). Pictured: Edwards after his 2005 win at Phoenix.

Brad Keselowski was 23 when he hit 18 starts. He had zero wins, zero top fives and zero top 10s, with two laps led for owner Keith Coleman. Keselowski ended up with five top-10 finishes in his age-23 season. Pictured: Keselowski with another of his team owners, Dale Earnhardt Jr., after his 2008 win at Bristol.

So, what's the final tally? Here are the leaders in each category after 18 starts: Wins (Byron and Edwards tied at 3), top fives (Byron and Busch tied at 7), top 10s (Byron with 12), laps led (Busch with 471). Seems like Byron is off to an A-OK start if you ask us.
