A late-race battle between Noah Gragson and Daniel Suarez started with cursing on the radio and ended up with a handshake on pit road in the NASCAR Cup Series race at Homestead-Miami Speedway.

Suarez was struggling to get around the lapped car of Ty Dillon in the No. 10 car, who was against the wall. The No. 7 team asked Dillon’s crew to get him off the wall so Suarez could use that line to get by.

Gragson was catching Suarez but was aero blocked by the No. 7 car of Suarez. Gragson said in frustration on the radio about Suarez, “Fucking cocksucker.”

For multiple laps, Suarez was trying to get around Dillon, but could not get around him. With 14 laps to go, Gragson’s car drifted up into Suarez, spinning out Suarez’s car. Gragson said on the radio that he got loose.

Suarez vented on the radio about the lapped traffic, “[The wreck] wouldn’t happen if the fucking No. 10 and the No. 62 [of Casey Mears] get the fuck out of the way.”

The No. 7 team said, “Should have just let Noah [Gragson] because you know he was going to hit something. That’s much of fault because he is an idiot.”

Under caution, Suarez drove his car back up to the No. 4 car of Gragson and gave him a thumbs up. Suarez’s spotter disapproved of Suarez coming up beside Gragson’s car as he said, “No, no, no, we are not doing that. Dude, you got to keep a clear head here.”

Both drivers recovered and finished inside the top 10, with Suarez finishing 8th and Gragson posting a season-tying best 9th.

The two drivers parked their cars next to each other on pit road and shook hands on pit road.

After the race, Gragson said on the incident, “That was 100 percent on me. I drove it down to the bottom, and I crossed the seam and got loose and I was chasing it. I didn’t want to get into Suarez, obviously. We were racing hard there at the end, but, truthfully, I never want to spin out a competitor. It kind of helped out both of us unfortunately with the caution, but a strong day.”
