The 2017 STP 500 was a Monster Energy NASCAR Cup Series race held on April 2, 2017, at Martinsville Speedway in Ridgeway, Virginia.

Contested over 500 laps on the .526 mile (.847 km) paperclip-shaped short track, it was sixth race of the 2017 Monster Energy NASCAR Cup Series season.

[12] Qualifying for Friday was cancelled due to rain and Kyle Larson, the point leader, was awarded the pole as a result.

[14] Clint Bowyer was the fastest in the final practice session with a time of 20.174 seconds and a speed of 93.863 mph (151.058 km/h).

[16] Trevor Bayne, Keselowski, Michael McDowell (speeding) and Joey Logano (crew member over the wall too soon) restarted the race from the tail-end of the field.

"[17] As a result of Keselowski's penalty, Martin Truex Jr., who was running second at the time, assumed the lead.

The third caution flew on lap 123 when Dale Earnhardt Jr. got loose exiting Turn 2, and received help from Ryan Blaney, and spun out on the backstretch.

[25] Hamlin got into Dillon and turned him, and the domino effect resulted in heavy damage to the cars of Kurt Busch and Daniel Suárez.

The 11th caution flew with 109 to go when Jeffrey Earnhardt blew a right-front tire and slammed the wall exiting Turn 2.

The resulting domino effect led to Bayne pushing Hamlin into the wall and Earnhardt slamming into the back of teammate Kahne, puncturing his radiator.

We don't have much of a bumper on there to begin with keeping the cars as light as we can and that is about the second or third time I've knocked the top off the radiator here.

[30] For the next 14 laps, Keselowski kept to the rear bumper of the 18 car, took the lead going into Turn 1 with 42 to go and drove on to score the victory.

It feels great to be able to join them and bring home a clock.”[32] “All we did was put four tires on it and it went to junk,” Busch said after leading a race high of 274 laps.

I really hope that we’ve found something or I have found something at this track that will lend some more consistent finishes that are further towards the front.”[34] Dillon, who rallied from a multi-car wreck in the middle of the race to finish fifth, said of the final run he "thought we were going to have a little something for the two leaders, but in middle of the run, our car just lacked a little bit more turn and forward drive," Dillon said.

Jamie Little, Chris Neville and Matt Yocum handled pit road duties for the entire race.

Joe Moore, Jeff Striegle and seven-time Martinsville winner Rusty Wallace called the race in the booth as the cars were on the frontstretch.

Alex Hayden, Winston Kelley and Steve Post worked pit road for the radio side.
