Denny Hamlin won Friday night's NASCAR Nationwide Series (NNS) race at Darlington Raceway.
Hamlin started from the pole and led four times for 111 (of 147) laps at the 1.366-mile track.
Kyle Busch finished second and led once for 17 laps.
It marks the ninth time since 2008 (80 races) that Joe Gibbs Racing drivers have swept first and second place finishes.
Kasey Kahne (fourth), Jason Leffler (fifth) and Brian Vickers (ninth) also recorded top-10 finishes for Toyota.
Camry drivers Michael Annett (11th), Steve Wallace (12th), Trevor Bayne (16th), Brian Scott (25th) and Brendan Gaughan (33rd) were also in the field.
Busch climbed to second in the unofficial NNS point standings -- 55 points behind leader Brad Keselowski. Joey Logano (seventh), Leffler (ninth), Bayne (11th), Scott (12th), Gaughan (13th), Wallace (14th) and Annett (15th) are also in the top-15 after 10 of 35 races.
KASEY KAHNE, No. 38 Great Clips Toyota Camry, Braun Racing
Finishing Position: 4th
Are you happy with your finish tonight? "It was a good night. I stayed off the wall during the race. (Jason) Leffler ran great. He ran out of gas to crank it left. I had to avoid him and (Jamie) McMurray made out there pretty good. It was still a good night for our Great Clips Toyota team did a good job. We just needed a little more to run with those two guys out-front."
Did it get crazy out there at times tonight? "Yeah, we were three-wide a few times and it was pretty crazy. There's barely enough room for two, let alone three. It was pretty cool. We were able to keep it off the wall tonight so it was good."
JASON LEFFLER, No. 10 ABF Freight Toyota Camry, Braun Racing
Finishing Position: 5th
Are you happy with your top-five finish tonight? "Yeah, it was an awesome night. I've got to thank all of my guys. I've got to thank Trip Bruce (crew chief) and everybody on my team and everybody at Braun Racing -- all of the other crew chiefs and teams were all really one big family so everybody pulled together and helped us out this week. The ABF Camry was really good. It's the most competitive we've been all year. It adds up that we have Trip Bruce here and we ran really well. I look forward to going to Dover and Charlotte and we can build on this. It's not too late in the season to still have a good season."
Was this finish what you needed to give your team some momentum? "It's perfect. We needed to finish some races for driver points and some owner's points. Kasey (Kahne) did a good job with the 38. It was fun racing him and Brian (Vickers) ran really well. It was fun. Darlington is always fun."
Did you have a problem with your transmission at the end of the race? "No, we were out of fuel. We cut it that close on fuel and it just burped that time. There was really no problem with the transmission other than the boot was holding it up from second to third and I kept missing. I think that caused the vibration. I'm sure I broke a valve screen or something. All in all it was a great run for us. We needed this. It was our first really competitive run of the year. I've got to thank ABF for coming onboard and Toyota for all of their support."

TREVOR BAYNE, No. 99 Diamond-Waltrip Toyota Camry, Diamond-Waltrip Racing
Finishing Position: 16th
How was your race today? "The Diamond-Waltrip Toyota was really good all day. I just got into Matt (Kenseth) there so we had to come down pit road and took tires and lost track position. We didn't get the finish we deserved today but it's definitely a step in the right direction for our team. The car was awesome today."
