LENS, France (Reuters) -A second-half goal from Przemyslaw Frankowski earned RC Lens their first victory over Lille in 15 years as they moved up to provisional second place in Ligue 1 with a 1-0 win after a derby marred by crowd trouble on Saturday.

Frankowski's strike ended a 12-game winless streak for Lens against the French champions, who had beaten them 4-0 and 3-0 last season.
