Sydney Swans midfielder Dan Hannebery's Brownlow Medal odds have been slashed, moving from a 100-1 shot at the start of the year into joint-second favourite behind only Gary Ablett.

After the 22-year-old collected an equal career-high 42 possessions against Adelaide on Saturday, some bookmakers have already moved Hannebery into a $9 chance (equal with reigning Brownlow medallist Jobe Watson), while others are expected to make the move when markets re-open.

Meanwhile, the red-hot Ablett is a short-priced favourite to take out his second Brownlow, already at $2 with some agencies.

TAB Sportsbet's Trent Langskaill told AFL.com.au Hannebery was into $15 ahead of round 11 and would shorten further.

"He has certainly been the big firmer of the season," Langskaill said.

"There always seems to be one or two during a season and this year it is clearly Dan Hannebery now.

"We had [Michael] Barlow a couple of years ago until he broke his leg and he was the absolute bolt out of the blue.

"Most people at the start of the year had [Gary] Ablett, [Jobe] Watson, Sam Mitchell and others and so forth but Hannebery has been one that's come from absolutely nowhere."

The 2010 NAB AFL Rising Star caught the eye of punters in round five when he collected 30 disposals against St Kilda to win the Anzac Medal at Westpac Stadium in Wellington.

But to win the medal, Hannebery will have to beat the Suns' superstar skipper who is sizzling form.

Langskaill said Ablett was $3.50 ahead of this round would be trimmed again following his 33-possession game in the Suns' 15-point win over North Melbourne.

"He's the clear favourite now," Langskaill said.

"Two weeks ago, him and Jobe Watson were equal favourites at $5.50.

"Considering last week, despite the fact they got run over in the last quarter by Geelong, he was probably best on, and again on Saturday night.

"Now, the fact they're actually winning the games, it's just going to help out even more. He didn't need much help when they were only winning two games anyway."

Last year Ablett polled 24 votes (six behind the winner, Watson) despite the Suns winning just three games for the year. This season the Suns have already won five games.
