Mark Martin was third in a Michael Waltrip Racing Toyota. Keselowski, who overcame two accidents earlier in the race, wound up fourth in Penske Racing's new Ford. Ryan Newman was fifth in a Chevy for Stewart-Haas Racing and was followed by Roush-Fenway Racing's Greg Biffle, who was second on the last lap but was shuffled back with Patrick to finish sixth.
Regan Smith was seventh for Phoenix Racing, while Patrick, Michael McDowell and JJ Yeley rounded out the top 10.
Patrick was clearly disappointed with her finish. When the race was on the line, she was schooled by Earnhardt, who made his last move and blocked any chance she had.
Still, Patrick became the first woman in history to lead laps in the 500 when she passed Michael Waltrip on a restart on Lap 90. She stayed on the point for two laps, then was shuffled back to third. She ended up leading five laps, another groundbreaking moment for Patrick, who as a rookie in 2005 became the first woman to lead the Indianapolis 500 and now is the 13th driver to lead laps in both the Daytona 500 and the Indy 500.
"Dale did a nice job and showed what happens when you plan it out, you drop back and get that momentum. You are able to go to the front," Patrick said. "I think he taught me something. I'm sure I'll watch the race and there will be other scenarios I see that can teach me, too."
Earnhardt was impressed, nonetheless.
"She's going to make a lot of history all year long. It's going to be a lot of fun to watch her progress," he said. "Every time I've seen her in a pretty hectic situation, she always really remained calm. She's got a great level head. She's a racer. She knows what's coming. She's smart about her decisions. She knew what to do today as far as track position and not taking risks. I enjoy racing with her."
