He thought he was about to watch Smith win as his driver pulled away from the pack on the final lap Friday night in the Nationwide Series race. Then, Kasey Kahne came charging through the outside lane, pulled alongside Smith and nipped him at the finish line.
No worries for Earnhardt: Kahne also was in one of JR Motorsports' Chevrolets.
"I was just glad that it was one of our cars when I saw somebody flying by on the top," Earnhardt said. "When I got a glimpse of it, I was happy to see it was (Kahne).
It was Kahne's first Nationwide victory since a 2007 win at Bristol while driving for Ray Evernham.
He hoped to translate it into another victory Saturday night in the Sprint Cup Series as Kahne looks for his first win of the season. Kahne is the only driver of the four Hendrick Motorsports drivers yet to win this season.
"This will carry. I haven't won in a while. To win in anything is good," Kahne said. "When I first came into this series in '02, I struggled to pick up stock cars. I'd go and race my sprint car and could still win in sprint car races and I'd come back feeling like I could win. ... I'd run 15th or 20th, but I still felt way better coming back into that race after running my sprint car. Any momentum is good momentum."
Kahne was 12th on a restart with three laps to go when Chase Elliott, another JR Motorsports driver, sputtered at the front of the field when the race went to green. It stacked up traffic behind Elliott and triggered a four-car crash that halted the restart.
Kahne maneuvered his way through the accident and found himself eighth when the race resumed for a two-lap overtime sprint to the finish. He weaved his way through traffic, but didn't appear to be in the mix for a shot at the win as Smith pulled away from the pack.
But as the field hurtled through the final turn, Kyle Larson jumped out of line and made it three-wide behind Smith.
Kahne moved into the top lane and, using a push from Ryan Sieg, charged alongside Smith and beat him to the line by .021 seconds.
"Everything I did tonight was wrong -- I looked in my mirror and would be like `Go' and then decide not to and it'd be the right move," Kahne said. "I didn't really do a whole lot right, but at the end, I got a big push from (Sieg) and was able to get by Regan there. Just had tons of momentum there coming off turn four and had a fast car."
Smith couldn't offer a better last-lap strategy then the one he used.
"If I go up any higher, we probably all wreck right there," Smith said. "I don't know how to do it any different. I'll have to study the tape and see where I messed up. I had a pretty good sized gap, but at that point you can't crack the throttle or drag the brake. I lost just enough momentum that it didn't quite work out."
It was the sixth win this season for JR Motorsports, and second consecutive following Kevin Harvick's victory last week at Kentucky.
"It feels good to win. These guys have won five times already this year, so it's nice to get one. It was a fun race."
Smith, one of JR Motorsports' two full-time drivers, wound up second in his return to Daytona following his victory in February's season-opener. Despite the defeat, Smith reclaimed the series points lead from Elliott Sadler.
"It's kind of bittersweet," Smith said. "I'm disappointed for the team, I'm disappointed for my guys, and selfishly I'm disappointed. But, for JR Motorsports, I'm happy. A 1-2 finish is great. It's kind of a weird mix of emotions right now.
"I'm happy for the company and frustrated for the 7 team."
Earnhardt was thrilled with the 1-2 finish and the sixth win for his company.
"I'm proud of the company and what they've been able to accomplish this year.
Sieg was a career-best third.
"It was a win for us," Sieg said. "Hopefully it will bring some more sponsors. It would be nice to have a full-time sponsor, hopefully we turned some eyes."
The performance earned huge praise from Earnhardt, who said he spent time watching Sieg race during last month's race at Dover.
"He impressed the hell out of me. I had not really paid a ton of attention to him prior to that, and I know those guys run on a shoestring (budget), but he had a couple of runs during the race at Dover that were better than anyone outside the top-five," Earnhardt said. "It's great to see him run well because I think he does a lot with very little."
