Selwood, who dragged his side back from a 32-point margin in the first quarter of Geelong's 59-point victory, had 29 possessions, seven tackles and two goals against the Giants, which equated to 31 player ratings points, the highest score in round 11.
Gold Coast superstar Gary Ablett (26.5), Geelong midfielder James Kelly (22.6), Collingwood's Steele Sidebottom (22.6) and Carlton forward Jarrad Waite (22.5) were the round's other leading scorers.
Essendon defender Jake Carlisle was well beaten early by Waite in Friday night's clash against the Blues, but he was the Bombers' match-winner after moving forward, and took a critical late defensive mark in his side's five-point victory.
His 23 disposals, 13 marks and one goal equated to a team-high 21.4 points and saw him rise 26 places to No.198 overall.
Waite still finished as the game's highest scorer after kicking five of his seven goals in the first half and finishing with 14 marks.
St Kilda midfielder Jack Steven, who laid nine tackles and had 19 possessions (14.2 points) in his side's four-point loss to West Coast, has continued his rise up the player ratings table.
The young Saint was ranked No.54 just five weeks ago, but he has risen to No.30 overall and is now his club's No.1 ranked player.
Ablett, who was at his best against North Melbourne on Saturday night with 33 possessions and two goals, remains the No.1 player in the AFL.
Sydney Swans star Josh Kennedy is No. 2, followed by powerful Adelaide midfielder Patrick Dangerfield.
Hawthorn's Lance Franklin and the Sydney Swans' Adam Goodes are the top two forwards, while West Coast's Shannon Hurn is the top-rated defender. Fellow Eagle Nic Naitanui is the leading ruckman.
