After a string of near misses in races this season, Sagan won the Ghent-Wevelgem classic in Belgium after out-sprinting his fellow escapees just two days after placing second at E3 Harelbeke behind Michal Kwiatkowski (Sky). The Slovak also placed second overall at Tirreno-Adriatico.
Sagan now sits seven points ahead of second-placed Richie Porte (BMC). Alberto Contador (Tinkoff) moves up from 10th to third after second place in Volta a Catalunya, with that race's winner - Nairo Quintana (Movistar) - entering the ranking in eighth.
Paris-Nice winner Geraint Thomas (Sky) slips from seventh to ninth, with fellow British rider and team-mate Ben Swift drops down to 12th. Chris Froome (Sky) enters the ranking for the first time this season after placing eighth overall in Volta a Catalunya.
With two riders in the top three, Tinkoff usurps Sky at the top of the team ranking.
Australia retains its place at the head of the nation ranking, with Belgium in second and Great Britain hanging on to third.
WorldTour points are awarded for one-day race, tour stage and stage race overall finishing positions for counting events.
The amount of points awarded depends on the ranking of the event. For example, winning the Tour de France overall gives a rider twice as many points as winning the Eneco Tour overall.
Next event in the 2016 WorldTour is the Tour of Flanders in Belgium on Sunday, April 3.
