Creed has achieved two second place finishes this season, tying with Dale Jarrett and Daniel Hemric for most second-place finishes before a victory.
"I'm running out of ways to lose these things," Creed said after the race.
Third place finisher Custer continues to lead the driver standings for Stewart-Haas Racing after Saturday’s race, despite failing to win a race this season.
"I felt like we had that one," Custer said.
"We had the best car all day and to have it ripped away with one lap to go is just heartbreaking.”
