FREMANTLE ruckman Aaron Sandilands says ruck tactics such as the 'third man up' are not having a major impact on his game, and the real battle at stoppages is being fought by the League's midfielders.

Coach Mark Harvey will seek AFL clarification this week on opposition tactics to hold Sandilands down at stoppages and send a third man up to win the hit-out.

But the All-Australian was more concerned with how the umpires govern Fremantle's midfielders, with free kicks to ruckmen at stoppages largely overlooked.

"It actually doesn't affect me as much with the free kicks, it's more the midfielders – what to do blocking wise and that – so I think [the holding rules] are more for them than me," Sandilands said on Wednesday.

"Harves is going to go seek clarification of that – he told me on Monday he was going to go to the media and speak about it. But he knows what's going on and he'll find out either today or tomorrow.

"It's just part of the game. Harves is just seeking clarification."

Sandilands, the League's tallest player, had more hit-outs than any other player in 2008, but his side ranked 15th in the AFL for clearances from a ruck duel.

That pattern continued in round one of the NAB Cup when Richmond dominated the stoppages in the second half and stole the match, despite Sandilands' 35 hit-outs to Richmond's combined total of 30.

But Sandilands said David Mundy's move into the engine room, Paul Hasleby's return and increased midfield chemistry would see Fremantle improve its effectiveness at stoppages in 2009. 

"Richmond was our first game for the pre-season, so you're always going to make mistakes. We made a few but we learned from that and moved on," he said.

"Last year, we didn't get off to a very good start with our clearances but we did improve.

"The guys have worked hard as a group over the last four or five months and I suppose the chemistry we're starting to build now, hopefully it'll start to show in games.

"I'm starting to build up some really good relationships with the midfielders and its good to have Paul Hasleby back in there every week. We've got Matthew Pavlich going through there as well.

"Blokes like David Mundy and Byron Schammer are stepping up and playing some really good football at the moment too, so it makes it easer."

Sandilands said he was looking forward to taking on the Western Bulldogs in 11 days' time at Subiaco Oval in Fremantle's 2009 Starlight Purple Haze Game, which will raise money for the Starlight Children’s Foundation.

"It's good to run out and see all that purple to be honest, and it's such a good cause," he said. 

"It's good to see the smiles on the kids faces in the change rooms before the games."
