Cycling-Froome in yellow but kept in check by Quintana (Reuters)
* Froome leads Quintana by 23 seconds * Colombian looks comfortable * Duo set for Mont Ventoux battle By Julien Pretot ANDORRA LA VELLA, July 11 (Reuters) – Once again, Chris Froome reached the first rest day of the Tour de France in yellow, but this year, his advantage is much thinner and his main rival Nairo Quintana is keeping his cards close to his chest. The Briton, who hammered the opposition in the first summit finish of the Tour in 2013 and 2015, leads fourth-placed Quintana, the runner-up in those two years, by 23 seconds. In 2013 and 2015, the Team Sky rider was leading Quintana by about 2 minutes going into the first rest day.
