Logano, who started 10th took the lead of the 267-lap race from Stewart-Haas's Kevin Harvick midway through the final stage and resisted Atlanta victor Keselowski's advances on the final lap to record the 22nd Cup victory of his career by 0.236 seconds. After Harvick pitted, Logano inherited the lead until he did the same on lap 50, leading to Daniel Suárez enjoying time in first.
Kevin Harvick of Stewart-Haas Racing finished fourth in a race he won in dominating fashion a year ago. For Keselowski, the win would've been a second-straight 2019 victory after he won a week earlier at Las Vegas Motor Speedway and a second-consecutive at LVMS after winning there last September.
Kyle Busch moved into position for a three-race weekend sweep in his hometown, holding on in double overtime to win the Xfinity Series race.
Kyle's brother Kurt Busch finished fifth.
Penske also wasn't anxious when his two drivers were inches apart on that final lap: "We've really told them to take care of each other, and the last 10 laps, the best man wins".
After three races, Busch sits 10th in the points standings just 38 points behind leader Joey Logano. "And then our pit strategist was saying if we stay long on the second stage, then we can stay out".More news: Facebook Messenger dark mode is here: How to unlock it
Joey Logano and Brad Keselowski were side by side off the fourth turn, two teammates fighting for the last burst of speed on the final lap at Las Vegas Motor Speedway.
Keselowski drove up from 19th to take the lead with 27 laps left, but his hopes for back-to-back victories were dashed when Logano passed him while getting held up by lapped traffic. With the lengthy green-flag runs, each stage included a cycle of green-flag pit stops. Logano and Busch were infamously involved in a pit road fight at the track in March of 2017 after they made contact on the last lap of the race.
"What a great race", he said.
But Busch ran out of time after passing Kevin Harvick for third place five laps from the finish. "We just still need that power feel of that attack to make sure we are the ones making the right call instead of trying to piece together the calls".
"Yeah, that was more intense than I wanted it to be." said Logano "There's been plenty of times here when we've led a lot of laps. I think we might be top Chevy again". When the green-checkered flag flew on lap 160, Logano led Harvick, Truex, Keselowski, Hamlin, Chase Elliott, Aric Almirola, Stenhouse, Alex Bowman, and Jimmie Johnson.
