Ryan Day ends Mark Selby's recent run with comeback win at the European Masters

World number one Mark Selby has been knocked out at the last 16 stage of the European Masters, after Ryan Day turned around a 2-0 deficit to come out a 4-2 winner in Lommel. 

Selby had done the same to Mark Davis from 2-0 down a day earlier, but this time it was the Welshman who was on the comeback trail to end Selby's winning run. 

Elsewhere, Luca Brecel just failed to complete his heroics of the last 32 and has been dumped out of his home tournament 4-3 by Anthony Hamilton. Brecel fought back from 3-0 down to beat Alan McManus 4-3 a round earlier and it looked like he was set to do the same after forcing a decider from three adrift against Hamilton, but the former German Masters champion held on to reach the quarter-finals. 

Joe Perry was in fine form to defeat Kyren Wilson 4-1, opening up with a century break on the way to an impressive win that puts him into the last eight. He will now face Tian Pengfei who backed up his victory over Judd Trump in the last 32, with a 4-2 win in the all-Chinese clash with Liang Wenbo. 

Mark King has won his three matches in Lommel for the loss of just two frames so far, after a 4-1 win against Ricky Walden continued his fine week and he will now play Ryan Day in the last eight. Mark Allen was made to battle for his spot on Friday's bill after Scotland's Ross Muir forced a decider from 3-1 down, before Allen got over the line. 

Meanwhile, Jimmy Robertson kept up his heroics of the week so far. Robertson had already overcome Zhang Yong and Zhou Yuelong on the black in deciding frames this week, while his last 16 opponent Anthony McGill had also won his two matches in deciders. It was no surprise then when the pair ended up at 3-3 on Thursday, before Robertson once again won the match on the final black. 

Finally, Jack Lisowski kept up his fine start to the season, despite a late start to his match with Zhang Anda. The left-hander is into his fourth quarter-final of the season and will now be looking to make his second ranking event final over the course of the next two days after defeating Zhang 4-2.

Quarter-final draw: (Picks in bold)

Joe Perry Vs Tian Pengfei
Jack Lisowski Vs Anthony Hamilton
Ryan Day Vs Mark King
Mark Allen Vs Jimmy Robertson

Joe Perry and Tian Pengfei have both had some good results against higher ranked players so far this week in Lommel to make the quarter-finals. Tian has beaten both Judd Trump and Liang Wenbo 4-2 in the last two rounds while Perry overcame Kyren Wilson comfortably in the last 16. Perry looked to be playing really well in that match with Wilson and he is well overdue a big run in a tournament, having slipped outside of the top 16 last year. This may not be a game that suits Perry entirely given the slow pace at which Tian operates, but given his play against Wilson and the added experience at this stage of a tournament that he has over Tian he is a more than worth favourite. 

Anthony Hamilton continued his fine start to the season with victory over Luca Brecel to book his place in the quarter-finals. After a disappointing year last time out, Hamilton looks to be back at full fitness and playing well, having already reached the last 16 of the season's first two ranking events. Lisowski meanwhile is still looking in good touch, after making the final in the season opening Riga Masters as well as the quarters at the World Open and Paul Hunter Classic. The only thing missing from his season really is a victory and looking at the names left in this competition he may see this as a huge opportunity, but that in itself can add pressure. The Paul Hunter Classic had a similar sort of feel before Lisowski lost a good lead to Peter Lines, having also done the same in the Yushan last eight tie with Mark Williams a few weeks earlier. Hamilton has all the tools and tricks to break Lisowski out of his rhythm and given the way both players are scoring this could be a very tight tussle.

Mark King will be looking to continue blitzing his way through the field this week when he faces Ryan Day. So far King has taken out Zhao Xintong, Stuart Bingham and Ricky Walden in Lommel for the loss of just two frames having also beaten Mark Allen 5-1 last week on the way to the last 16 of the China Championship. Day though is playing well himself, battling hard to beat Elliot Slessor 4-3 in the last 32 before yesterdays comeback win against Mark Selby. With his confidence growing by the match, King is not a player that should ever be underestimated, especially since winning his maiden ranking title two years ago. This looks like a pretty even match on paper given current form, with Day not exactly getting off to a flying start in the new season, so this presents a big opportunity now for both players to add to their ranking title tally. 

If Mark Allen has been keeping in touch with this week's results he will know the importance of getting the job done against Jimmy Robertson before the match can get to a deciding frame. Robertson has had fortune on his side so far this week winning all three of his matches in deciding frames and on the final black, which is quite incredible. Zhang Yong, Zhou Yuelong and Anthony McGill are the three players to have suffered those heart-breaking defeats, though if Robertson is to make his maiden ranking semi-final, for the sake of his heart rate he probably would not mind doing it a frame or two earlier than what has become his norm this week. Allen meanwhile has also needed a decider this week against Ross Muir, while beating Jak Jones 4-2 and Ashley Hugill 4-1 despite claiming that he is not happy with his performances this week. If Allen can up his game over the rest of the week then he could be in with a shout on Sunday evening. 

All four quarter-finals on Friday will be played over the best-of-7 frames on the main TV table, broadcast live on Eurosport, with places in Saturday's semi-finals up for grabs.
