"The problem was I called him down pit road too late and he missed pit road," said Osborne, as frustrated as his driver after the two had words following the race finish. "At that point, we looked at our options and decided to take our chance on a caution, and the caution didn't come. We just ran it to the end and did a splash-and-go when the caution didn't come. It just didn't go our way. We didn't get the job done."
The result leaves Edwards on the wrong side of the post-season Chase cut-off line with time running out. He had no wins to fall back on, and hasn't even finished in the top ten once in June. That's quite a slump for the driver who tied the Tony Stewart on points last year for the Cup championship.
In terms of his own title hopes, Keselowski might only be one spot ahead of Edwards in tenth place in the NASCAR Sprint Cup Series championship standings and therefore technically 'on the bubble', but his third win of the season means that - much like last year - he's now virtually assured a spot in the Chase via the 'wins wild card' system at the very least.
"Now we can look forward," Keselowski said of that position. "We don't have to look back at all, and that's so big."
Matt Kenseth continues to lead the series with nine races to go before the Chase cut-off. His margin is 11pts with Dale Earnhardt Jr. having moved up to second place with Jimmie Johnson in third, after a poor finish for former points leader Greg Biffle saw him tumble two spots to fourth.
After their second and third place finishes at Kentucky, Kasey Kahne and Denny Hamlin are the biggest gainers near the top of the points with jumps of three places each to 14th and fifth positions respectively, while Tony Stewart's technical gremlins drop the reigning Cup champion four places to ninth.
