SYDNEY Swans midfielder Kieren Jack has jumped to eighth in the Official AFL Player Ratings, brought to you by Vero, after his best on ground performance against Melbourne at the MCG on Sunday.

Jack was the leading point-scorer in round 15, with his 31 possessions and a goal in the win over the Demons equating to 25.1 ratings points.

Having started the season in 17th place, he is now just one point behind the seventh-best player in the competition, Hawthorn's Cyril Rioli.

Collingwood midfielder Scott Pendlebury tallied the second-highest score of the round.

He gathered 33 possessions and kicked a goal in the Magpies' brilliant win over Carlton at the MCG on Friday night, which equated to 24.5 player ratings points.

A couple of defenders also had big weekends.

            

West Coast backman Eric Mackenzie tallied a career-best score of 22.6 in the Eagles' gutsy win over Adelaide at AAMI Stadium on Saturday night.

The 25-year-old took five intercept marks, spoiled the ball 13 times and registered 477m gained from his 21 disposals.

Mackenzie spent most of the night matched up on Crows forward Josh Jenkins and kept him goalless. He conceded one goal during a brief stint on Tom Lynch.

Essendon's Cale Hooker earned the second-highest score in the Bombers' win over Port Adelaide at Etihad Stadium on Sunday evening.

The key defender's score of 21.5 was bolstered by his eight intercept marks. In fact, he leads the competition this season for winning the ball off the opposition.

Hooker's performance saw him climb 26 places to 211 on the player ratings table, which was the greatest rise of any player within the top 400.

Greater Western Sydney midfielder Devon Smith is also racing up the charts. After starting the season at 443, he has climbed to 290.

Smith earned the highest player ratings score in the match between the Giants and the Western Bulldogs in Canberra on Saturday afternoon.

He finished with 19.8 points, which came thanks to 24 disposals, two goals, 733m gained and 30 pressure acts.

Smith has averaged 24 pressure acts per game this season, which is the second-best average in the competition.

Despite not playing on the weekend, Gold Coast captain Gary Ablett remains the top-rated player in the AFL.
