Ronnie O’Sullivan crashed out of the English Open after losing 4-1 to Matthew Stevens in the third round.
O’Sullivan had opportunities in most frames but his misses were ruthlessly punished by Stevens, who made breaks of 58, 73 and 116 - and finished with a 98 per cent pot success - to secure an impressive win.
Stevens will face Jak Jones in the last 16 this evening.
Stevens sinks perfect plant against O'Sullivan
“I started well, I think you have to against Ronnie otherwise he puts you on the back foot," said Stevens.
"The key to beating him is you have to put him under pressure and he missed one or two.
"He does that to his opponents and I thought if I can get out the blocks I have nothing to lose and I hit the ball well.”
While Stevens produced a high-quality performance to advance, he also took advantage of several missed opportunities from O’Sullivan.
