NASCAR Xfinity Series: Who won the Hard Rock Bet 300 at Homestead-Miami?

Following Justin Allgaier's win in Las Vegas, the NASCAR Xfinity Series made its sixth stop of the season in Saturday's running of the Hard Rock Bet 300 at Homestead-Miami Speedway. It was the series' second consecutive race on a 1.5-mile track and marked the first of four Dash 4 Cash races.

Joe Gibbs Racing rookie Taylor Gray - one of four rookies in the top five to begin the race - led the field to the green. The first stage was slowed three times, with rookie Christian Eckes of Kaulig Racing being the first casualty as his Chevrolet began to smoke down the backstretch on Lap 17. After a couple solo spins from Kris Wright on Lap 30 and Justin Bonsignore on Lap 37, JR Motorsports' Sammy Smith took advantage of fresher tires and got around Kyle Sieg in Turn 4 to win Stage 1.

Stage 2 would go caution-free with Cup Series regular Kyle Larson winning the stage. Larson, who led a race-high 132 laps, appeared to be on his way to a comfortable win, which would have put him in position to win all three races at Miami this weekend. Instead, Gray spun down the frontstretch after making contact with the wall on Lap 193 of the 200-lap race. That set up an overtime finish with Larson, Austin Hill, Allgaier and Sam Mayer battling for the race win.

After Larson spun his tires and Mayer shoved him from behind, Hill and Allgaier surged in front. Allgaier would get clear of Hill prior to the white flag and hang on to win for the second week in a row, but the first time in his career in 17 starts at Homestead-Miami. Although Allgaier was penalized for driving through too many boxes on pit road after Stage 1's conclusion, he was able to rally for the win, which also clinched the No. 7 JR Motorsports driver the $100,000 Dash 4 Cash bonus over Mayer (second), Hill (third) and Love (sixth). As the four highest-finishing full-time drivers, Allgaier, Mayer, Hill and Creed will go for the Dash 4 Cash bonus next Saturday at Martinsville Speedway.

Allgaier holds a 29-point lead over Mayer as the series heads to Martinsville Speedway for the running of the US Marine Corps 250 on Saturday, March 29 (5 p.m. ET, The CW, MRN Radio, SiriusXM NASCAR Radio). Aric Almirola is the defending race winner.
