The Trackhouse Racing star had an excellent day at Texas Motor Speedway on Sunday, bringing his No. 1 Chevrolet home in second and falling just short of the win after a late charge to the front.
Despite this, Chastain has actually lost ground in the Cup Series standings, falling from 10th to 11th. This has happened due to Wurth 400 winner Joey Logano jumping two spots from 11th to 9th, demoting Chastain in the process.
Chastain was not the only driver in the top 10 to be demoted, however, with Bubba Wallace and Alex Bowman also falling by one spot each in the standings following Sunday's race.
Elsewhere, Hendrick Motorsports continue to dominate the standings, with William Byron leading the way ahead of Kyle Larson, and Chase Elliott not too far behind in fourth.
Meanwhile, Denny Hamlin retains third despite his Texas DNF after his car caught fire, whilst 23XI star Tyler Reddick rounds out the top five heading into next weekend's action at Kansas.
With that said, let's take a look at the latest Cup Series standings in full.
