Hendry beaten despite 147 break

It was Hendry's 10th maximum, putting him level with Ronnie O'Sullivan, but he then lost the next three frames.

World champion Neil Robertson lost 4-1 to Graeme Dott and Matthew Stevens beat Ryan Day 4-3 to reach the last eight.

Ali Carter ousted obdurate Peter Ebdon 4-1 and will play Ding Junhui, who came from 3-1 down to beat Mark Allen 4-3, with a break of 79 in the final frame.

Hendry, the seventh player to make a 147 this season, could not find his rhythm again after his magnificent start and his next highest break was 49.

Asked about his maximum he said: "Who cares? I lost my focus in the second frame, I had about 59 chances to win it but couldn't take them. After that I was garbage, total garbage. I had enough chances to win the whole tournament."

Maguire, who plays world number two Mark Williams in the quarter-finals, recorded a fluent 129 in frame three and closed out the match with a 55 after a mistake by Hendry on a straightforward red.

Dott avenged last year's World Championship final defeat against Robertson, with four consecutive frames after the Australian had taken the opener with a break of 51.

The Scot levelled after a scrappy second frame then reeled off three successive half century breaks.

Stevens won the opening frame against his fellow Welshman with a 58 but Day, who beat Ronnie O'Sullivan in round one, came from 3-1 down to force a decider which Stevens eventually took after a break of 66.

The match produced some high quality break building, with Day levelling at 1-1 after a well-crafted 89.

Stevens went ahead again with a 43 but Day compiled a 74 and then took the match to the final frame.

Day responded to his opponent's 66 with a 42 but after a tense tactical battle on the brown, world number 21 Stevens, twice a beaten finalist at the World Championship, prevailed to book a quarter-final against defending champion John Higgins.

"I was feeling comfortable at 3-1 and missed a simple black. I should be out, I'm just pleased to be through," Stevens said.

"I love playing John, he's one of the all-time greats and I'm really looking forward to it. It's probably the first time I've been in the quarter-finals of the Welsh for about 20 years!"

World number eight Carter raced into a 3-0 against Ebdon, the world number 12, and closed out the match with a break of 74.

Williams whitewashed Jamie Cope 4-0 but said: "It looked easy on paper, but Jamie could have won a couple of them. It's flattering - it wasn't a 4-0 match."

Meanwhile Ding fought back from 3-1 down to beat Allen 4-3 and set up a last eight meeting with Ali Carter.
