NIMES, France (AP) — Alexander Kristoff of Norway captured his second stage win of this year’s Tour de France by leading home a pack that overtook two breakaway riders with only about 50 meters to go in a dramatic finish to Stage 15 on Sunday.

Vincenzo Nibali of Italy, having made sure that his main rivals couldn’t claw back any time, finished smoothly in the trailing pack to keep the overall leader’s yellow jersey.

After two days in the Alps, Sunday’s stage offered some relief over a flat 138 miles from Tallard, southeast France’s parachuting capital, toward the city of Nimes — known for its Roman arena and bullfighting.

Kristoff, a Katusha rider who also won Stage 12, lifted a fist after leading the sprinters who surged ahead of the two breakaways — Swiss champion Martin Elmiger and Jack Bauer of New Zealand — who had led the stage virtually since the starter’s gun.

Nibali kept his main rivals for the Tour title at bay. He leads Spain’s Alejandro Valverde, in second, by 4:37, and Romain Bardet of France is third, 4:50 behind. American Tejay van Garderen trails in fifth, 5:49 back.

Nibali, the leader of Kazakh team Astana, is looking likely to take home the yellow jersey when the threeweek race finishes next Sunday in Paris.
