GAP, France (AP) — A brief look at Tuesday's 16th stage of the 100th Tour de France:

Stage: A 168-kilometer (104-mile) route starting from the Provence village of Vaison-la-Romaine in the heart of the Rhone winemaking country and finishing in the foothills of the Alps in Gap.

Winner: Portuguese rider Rui Costa won after a solo breakaway up Col de Manse, the last of the day's moderate climbs. He crossed the line 42 seconds ahead of Frenchman Christophe Riblon.

Yellow Jersey: Chris Froome. The British rider still leads Dutchman Bauke Mollema by four minutes, 14 seconds and Contador by 4:25. Froome and Contador both had trouble on a speedy descent down to Gap, with Contador falling and Froome swerving left to narrowly avoid him.

Stat of the day: 22:01. The gap between Costa and Belgian Kris Boeckmans, the last of the 179 riders to finish the stage.

Quote of the day: "It was a bit dangerous from Alberto to ride like that, it's not good" — Froome, blaming Contador for riding too dangerously on the descent.

What's next: Froome will be among the favorites to win Wednesday's 17th stage, a 32-kilometer (20-mile) time trial from Embrun to Chorges. He came second in the Tour's first time trial last week.
