SYDNEY Swans ruckman Mike Pyke is confident he has done enough in his 10 games this year to earn a new contract as a senior-listed player.

In just his second year playing Australian football, the former Canadian rugby union international has impressed as a back-up to Shane Mumford after incumbent senior ruckman Mark Seaby broke his ankle in round six.

Pyke's current deal as an international rookie ends after the 2010 season, and he said his manager had opened talks on a new contract to stay at the club.

"I think now I've proven I can hold a second ruck role. I'm learning where to go on the field and when to be there, so hopefully the club comes to the decision to keep me on, and that's what I want to do," he said.

"I guess if it doesn't work out here, you have to look to all options available. At the moment though, I'm very happy in Sydney and this is where I want to stay."

Pyke said playing a string of senior games had fast-tracked his development, along with intensive tactical instruction from Swans coaching co-ordinator John Longmire.

A stint playing as a key defender with the Swans reserves at the start of the year also helped him feel more comfortable taking on some of the game's best big men.

"I think last year, a big concern of [the clubs] was me getting stuck on someone like (Justin) Koschitzke and him taking me forward and not being able to defend that," he said.

"This year, playing in the reserves and playing at full-back has really helped my defensive capabilities, and now I think I'm starting to string together a bit of an offensive role and sneaking forward a bit."

Swans coach Paul Roos said Pyke had done an exceptional job as a No.2 ruckman in Seaby's absence.

"Probably because Mummy's been playing so well, he probably hasn't got the kudos that he perhaps could have," Roos said.

"Last year we saw him play, and he struggled in a lot of areas of the game [but] his tap ruckwork was very good.

"This year, if someone came to their first game, you'd have to point out that this is a Canadian rugby player now playing AFL football, and that's the biggest compliment you can give Pykey."

Roos said he expected Pyke to be offered a new contract for 2011, and acknowledged that there would be some competition for the big man's signature in the unlikely event that the Swans decided not to offer a new deal.

"That's probably a potential danger for us. If teams were looking at us, he's certainly now a bona fide AFL ruckman but we'd like him to stay here. I'm sure Horse (John Longmire) would say the same thing if he was here," Roos said.

Pyke conceded that he had some early doubts about his ability to make it in the AFL, but he described his efforts in 2010 as "a significant point in my sporting career".

"When I first arrived, it was quite overwhelming [with] the skill set I had to come to grasps with," he said.

"I looked at guys who had been here for a year, Irish guys like (former Swans rookie) Brendan Murphy and thought, 'Geez, I'm a fair bit off that. Am I actually going to be here in six months?'

"Once I got to grips with the basic skills, I started getting more confident, and obviously getting eight games last year was a huge bonus."
