In his 100th AFL game, the Tasmanian's best-afield display followed a haul of six goals against Hawthorn last week, catapulting him to the top of the Coleman Medal table.

After a slow start to 2012 following off-season hip, shoulder and finger surgery, Riewoldt says he has turned his form around by concentrating on the basics.
"The biggest thing for me has been trying to get back to jumping at the footy, and applying forward pressure," he said after the eight-point win over the Saints.
"I know internally I've been happy with the way I've been putting pressure on, and ultimately the wheel turns in AFL footy, and if you continue to do stuff like that, eventually you're going to get on the end of a couple."

Riewoldt described his five-goal first half as his best of the year so far, and admitted his past fortnight had been a confidence booster.
"My body's starting to feel really good," he said.
"I'm happy with where my head's at, and going forward the confidence of this group is growing day by day, week by week."
The 23-year-old's bag of goals was the largest of any player so far this year, and the second-biggest of his career behind the 10 he kicked against West Coast in 2010.
The milestone game performance was capped off perfectly when he slammed home the sealing goal in front of a rapturous Tigers cheer squad.
"You love playing for this footy club for moments like that," Riewoldt said.
"There were so many people that came to the game tonight that bleed yellow and black, that are passionate supporters, and to win a game on the big stage, Friday night footy, with a lot of people watching, is important for this group and the way we're going to develop in our maturity.
"We're very proud of the way we played."
Richmond coach Damien Hardwick said he was pleased to see his big forward get reward for his hard work.
"We needed Jack to stand up, there's no doubt about that," Hardwick said.
"He was playing below expectation at certain stages throughout the year.
"Defensively he's been very good. I think he's number three in the league in forward-50 tackles, which is important.
"The defensive elements of his game today were outstanding once again, and there's no doubt it helps get the easy rewards from goals.
"It was good to see his marking was back to where we know it could be.
"He's had his hands on them, but just wasn't taking them. So that was really pleasing."
