Playoff standings: How national series fields shape up heading into Dover

Shane van Gisbergen made it three wins in five races as he crossed the start/finish line comfortably ahead of Chase Briscoe on Sunday at Sonoma Raceway. After the recent run of road courses in the schedule, the NASCAR Cup Series will head back to the ovals for the next three weeks, starting at Dover Motor Speedway. Read on to see full playoff standings and key battles in each of NASCAR's three national series. As a reminder: A win provisionally clinches a playoff spot for full-time drivers in all three series, and it's the simplest path to the postseason. The remainder of the postseason field -- 16 drivers in Cup, 12 in Xfinity and 10 in the Craftsman Truck Series -- is determined by points earned over the regular season.

NASCAR CUP SERIES

By clicking on the "Playoff Picture" tab on our standings page, you'll see SVG is now in third place ahead of Christopher Bell. SVG has one more playoff point based on three race wins and two stage wins versus Bell's three race wins and one stage win. Hard to believe for a guy who, before this recent run of road-course dominance, sat 33rd in the standings. Drivers provisionally qualified for playoffs with a win (12): Kyle Larson (three wins), Denny Hamlin (three wins), Christopher Bell (three wins), Shane van Gisbergen (three wins), William Byron, Chase Elliott, Ryan Blaney, Chase Briscoe, Ross Chastain, Joey Logano, Austin Cindric and Josh Berry. Winless drivers more than 100 points above the elimination line (one): Tyler Reddick (+149). Biggest movement: Thanks to his 10th-place finish at Sonoma, Kyle Busch gained nine points against the elimination line and now sits minus-37 heading to Dover. Three of Busch's seven top-10 finishes this season have come on road courses, including two in a row the last two weeks. Alex Bowman lost seven points against the elimination line after Ty Dillon bumped him out of the way on the last lap to win their In-Season Challenge matchup. In addition to losing to Dillon, Bowman's 19th-place finish at Sonoma dropped him to just 32 points above the elimination line as he dipped beneath Chris Buescher in the playoff standings. Note: Drivers in bold have provisionally clinched a playoff spot by virtue of winning. There are six races remaining in the regular season. [table id=479 /] NASCAR XFINITY SERIES Connor Zilisch picked up his third win of the season by outmaneuvering teammate Shane van Gisbergen at Sonoma. The 18-year-old wunderkind joined Justin Allgaier and Austin Hill with three wins this season. However, Zilisch's victory meant the number of unique winners in the series stayed the same at seven this week. Drivers provisionally qualified for playoffs with a win (7): Justin Allgaier (three wins), Austin Hill (three wins), Connor Zilisch (three wins), Jesse Love, Brandon Jones, Nick Sanchez and Sammy Smith. Winless drivers more than 100 points above the elimination line (one): Sam Mayer (+163). Biggest movement: Thanks to his eighth-place finish at Sonoma, Carson Kvapil gained 27 points against the elimination line and sits just below the 100 club at plus-90 points to the good. In fact, everyone above the elimination line gained points at Sonoma: Sam Mayer (+14), Sheldon Creed (+24), Taylor Gray (+14) and Jeb Burton (+4) all joined Kvapil. This meant most of the drivers below the elimination line lost some ground, with the biggest losers being Christian Eckes (-21) and Ryan Sieg (-20), who plummeted thanks to 34th and 35th place finishes at Sonoma, respectively. Note: Drivers in bold have provisionally clinched a playoff spot by virtue of winning. There are seven races remaining in the regular season. [table id=480 /]

NASCAR CRAFTSMAN TRUCK SERIES

The Craftsman Truck Series is off until July 25 at Lucas Oil Indianapolis Raceway Park, so there were no changes in the standings this week. Drivers provisionally qualified for playoffs with a win (7): Corey Heim (five wins), Chandler Smith (two wins), Layne Riggs, Tyler Ankrum, Daniel Henric, Stewart Friesen and Rajah Caruth. Note: Drivers in bold have provisionally clinched a playoff spot by virtue of winning. There are three races remaining in the regular season. [table id=456 /]
