William Bonnet of France won a sprint Tuesday to take the second stage of the Paris-Nice race, and Lars Boom of the Netherlands maintained the overall lead. Bonnet surged ahead in the last few meters to beat Peter Sagan of Slovakia on the finish line. Defending champion Luis Leon Sanchez of Spain finished third and moved up to third overall thanks to time bonuses awarded for his podium finish. Four riders were involved in a crash near the end of the 201-kilometer stage between Contres and Limoges after Slovenian sprinter Grega Bole fell just in front of Jimmy Casper of France in the last stretch. Following his crash in the first stage, two-time Tour de France winner Alberto Contador spent the whole day in the pack and remains 25 seconds behind Boom. Boom, who won Sunday's prologue, leads the overall standings by five seconds ahead of German rider Jens Voigt. Sanchez is 10 seconds back.
