World number three Neil Robertson was a surprise casualty on day one of snooker's World Grand Prix, going out 4-3 to Peter Ebdon.
Robertson was unable to find any fluency against the gritty Ebdon, who took a decider in a low-scoring clash with a 69 break.
"It was a tough match and I'm delighted to win," Ebdon told World Snooker's official website.
"I butchered a few balls but it's hard to get over the line when you haven't been getting results. I was very focussed and felt I had a chance of winning. Things haven't been going for me this season and I'm looking for consistency."
Ding Junhui also went to a decider but the Chinese prevailed, knocking out Ben Woollaston with his highest break of 61 getting him over the line.
Elsewhere, Barry Hawkins was whitewashed 4-0 by Joe Perry and Martin Gould beat Tian Pengfei by the same scoreline.
More surprising was John Higgins' clean sweep of fellow Scot Stephen Maguire, Higgins putting together a run of 92, 54, 69 and 79.
