NASCAR heads to Kentucky this week for the Quaker State 400, as they get back to intermediate-track racing to take on a perilous 1.5-mile track at Kentucky Speedway. Martin Truex Jr. has had tons of success on intermediate tracks in the last few years, as has been well documented, and he will be looking to defend his title in Kentucky Saturday at 7:30 p.m. on NBCSN. Truex has been very good in two runs at Kentucky since the re-pave in 2016 and has had great recent success this season with two wins, three runners-up finishes and seven top 5s in his last eight races. He will be the man to beat Saturday. Brad Keselowski won the 2016 race and holds the second best driver rating at Kentucky Speedway.
