Logano is in the Chase for the first time in his fifth season of Sprint Cup competition. He's also in his first year driving for Penske Racing in Cup and Nationwide.
When Nationwide ran at this track in July, Logano passed Sam Hornish Jr., his Penske teammate, for the lead after a restart with 15 laps to go. He beat Hornish to the finish line by 0.3 seconds for his second and most recent win of the season.
Logano has notched two wins and four top-10 finishes in five Nationwide starts at Chicagoland. His first victory here came in 2009.
"That type of track just really suits my driving style," Logano said. "I like fast, wide tracks where you and run at the top or at the bottom."
Saturday's 300-mile race at Chicagoland will be Logano's 12th start in Nationwide this season, driving the No. 22 Ford for Penske. His first win this year came in June at Dover. Brad Keselowski drove the No. 22 car to victory one week ago at Richmond.
Last year, Logano competed in 22 Nationwide events, recording a season-high nine victories. It was his final year with Joe Gibbs Racing.
"This is the fewest Nationwide Series I've raced up to this point in a year in my career, and that's ok, because we've been having a lot of success on the Cup side, but it's been fun," he said. "I didn't get into the car until April, and it only took a couple of races to win our first event together as a team."
Logano is one of five Sprint Cup regulars competing in this race. Kyle Busch, Dale Earnhardt Jr., Kevin Harvick and Matt Kenseth are the others.
Hornish enters the race with a 15-point lead over Austin Dillon and a 26-point advantage over Regan Smith. Elliott Sadler is 28 behind. Hornish has been atop the Nationwide standings since the Aug. 17 inaugural event at Mid-Ohio.
Forty-three teams are on the entry list for the Dollar General 300.
