Ronnie O'Sullivan exits Grand Prix on first day in Llandudno

Ronnie O'Sullivan was a first-day casualty at the World Grand Prix in Llandudno on Tuesday as he crashed out to Michael Holt.

O'Sullivan - without a ranking defeat in 2016 - looked set to go home with a whimper as he slumped 3-0 down, Holt running up scores of 88 and 119.

But the five-time champion replied to level at 3-3 before Nottingham man Holt cracked in a 76 in the decider.

The 40-year-old's exit came on a day of shocks, with world No 3 Neil Robertson going out 4-3 to Peter Ebdon. 

The Australian was hindered by the gritty Ebdon and unable to find any fluency, with Ebdon taking a decider in a low-scoring clash with a 69 break.

"It was a tough match and I'm delighted to win," Ebdon said. "I butchered a few balls, but it's hard to get over the line when you haven't been getting results.

"I was very focused 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 was also taken 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 and Ryan Day beat Matt Selt 4-1.

More surprising was John Higgins' clean sweep of fellow Scot Stephen Maguire, Higgins putting together runs of 92, 54, 69 and 79.
