Jimmie Johnson is the leader at the halfway point of the Citizen Soldier 400 at Dover International Speedway.
Johnson started eighth and has led 11 of 200 laps. He took the lead on a restart on Lap 190, passing Martin Truex Jr. Truex started second and has led 81 laps. He took the lead for the first time on Lap 6, passing pole-sitter Brad Keselowski.
Kyle Busch is the only other driver to lead during the first half of the event. Busch has led twice for 102 laps.
Chase drivers were eight of the top 10 at halfway with Johnson leading Truex, Keselowski, Matt Kenseth, Busch, Chase Elliott, Joey Logano, Denny Hamlin, Kasey Kahne, and Jeff Gordon.
There have been four cautions in the first 200 laps. Chase driver Kevin Harvick, who already is locked into the Round of 12 after winning last weekend at New Hampshire Motor Speedway, brought out the first caution on Lap 33 when he suffered a broken track bar mount. Following repairs in the garage, Harvick returned to the race on Lap 77 and was running 39th, 44 laps down at halfway.
Under the same caution, Chase driver Kyle Larson lost power in his No. 42 Chevrolet and had to be pushed to pit road. Larson lost a lap while the team worked on the car and then was called for a pass-through penalty for having too many crew members over the wall.
The second caution was for Ryan Blaney, who blew a tire coming off Turn 2 on Lap 104. Larson then brought out the third caution when he blew a tire on Lap 182. The fourth caution was for Larson’s teammate, Jamie McMurray, who blew an engine on Lap 193.
