Walden won the third world ranking title of his career - and biggest to date - at the 2014 International Championship in Chengdu, China. He beat Mark Allen 10-7 in the final to bank the £125,000 top prize.
Walden added one piece of silverware to his trophy cabinet during the 2013/14 season. He beat Marco Fu 4-3 in the final of the Bluebell Wood Open European Tour event in Doncaster.
His best run in a full ranking event came at the UK Championship as he reached the semi-finals, notably beating Ding Junhui, who had won his previous 22 ranking event matches.
"I seem to get better each game when I come to these tournaments and as long as I stay in them then I've got a chance of playing even better in the next round. That's how my game goes really," said Walden, though he ended up losing 9-5 to Mark Selby in the semis.
At the World Championship, Walden beat Kyren Wilson in the first round but then suffered a 13-11 reverse in a tough battle against Barry Hawkins.
Walden's 2012/13 season was bookended by superb displays in the Wuxi Classic and the World Championship.
At the former he beat Stuart Bingham 10-4 in the final - despite a 147 from his opponent - to win his second ranking title. Both of his crowns have come in China.
"It's great to play out in China, the game's getting bigger and bigger over here," said Walden. "There's going to be more and more tournaments over here, if you can learn to win in China then it's a good thing because the tournaments are slightly different than they are in the UK."
He had never previously won a match at the Crucible but proved his ability to thrive on the big stage by knocking out Michael Holt, Robert Milkins and Michael White. And he looked set for the final when he led Barry Hawkins 6-2, but eventually lost 17-14.
"I've got to the semi-finals of the World, I have done the semi-finals of the UK and won a couple of ranking events so I am not too far away. I am improving and getting better," said Walden.
The 2008 Shanghai Masters will live forever in the memory of Walden as it gave him his first ranking title.
And the talented Chester-based potter did it the hard way, dispatching snooker legends and rising stars alike on his way to the trophy. Walden knocked out Stephen Hendry, Neil Robertson, Steve Davis and Mark Selby to set up a final clash with world No 1 Ronnie O'Sullivan, then played brilliantly to register one of the shocks of the season with a 10-8 victory.
"I'm thrilled to bits to win my first tournament," said Walden. "I hope I can go on and achieve more now. I want to get into the top 16 and win more tournaments."
Walden is a keen Liverpool fan and often visits Anfield to watch the 2005 European champions. He enjoys travelling and frequently flies to Las Vegas with his friends. For a while he was an enthusiastic long distance runner and took part in the New York Marathon in 2009.
He married Natalie, his girlfriend since 2010, at New York City Hall in 2014.
