Charlie Curnow has reached new heights for Sydney, kicking eight goals to power the Swans to a 114-point demolition of Richmond.
Curnow slotted six first-half goals and Isaac Heeney kicked five all up as the Swans outclassed the Tigers 25.20 (170) to 8.8 (56) in front of 38,013 fans at the SCG on Saturday.
Despite a raft of injuries, Sydney pulled off the highest-scoring first half of the year, kicking 15.7 (97) to 7.4 (46) at halftime to outdo Adelaide's 14.6 (90) against North Melbourne in round 11.
It was the perfect way for the second-placed Swans to return to the winners' circle, after suffering their first defeat in eight games last round to Geelong.
Sydney (10-2) are a chance of returning to the top spot of the ladder if reigning premiers Brisbane deny leaders Fremantle (10-1) a record-extending 11th straight victory at the Gabba later on Saturday.
