Ronnie O'Sullivan hits maximum break on way to exiting China Open
Ronnie O'Sullivan chalked up his 14th maximum 147 break - but was still knocked out in the first round of the China Open 6-2 by Elliot Slessor.
O'Sullivan, 42, produced the perfect clearance in the fifth frame to secure the £42,000 prize fund.
However, it was 23-year-old Slessor who progressed, having earlier opened up a 4-0 lead before going on to secure his place in the second round at the expense of the world number two.
There was also another unexpected result in Beijing, as Chris Wakelin coasted past Shaun Murphy, the world number seven, with a 6-0 victory.
World number one Mark Selby, though, had no such problems as the defending title holder saw off Scott Donaldson 6-4, having cleared 16 reds in the second frame on his way to a break of 141.
In the other evening matches, home favourite Ding Junhui - the world number four - beat Craig Steadman 6-4, with Australian Neil Robertson, Mark King, Xiao Guodong, Kyren Wilson and Welshman Michael White also progressing to round two.
Elsewhere on Tuesday, Scotland's John Higgins, the world number five, saw off Martin O'Donnell 6-2, while Irishman Fergal O'Brien edged out Stephen Maguire 6-5 as Barry Hawkins, Graeme Dott and China's Yan Bingtao also advanced.
The closing matches of the day saw Chinese amateur Luo Honghao pull off an upset when he beat world number 16 Anthony McGill 6-4, while Michael Holt
and Tom Ford also safely moved into the second round.
The China Open is the last event ahead of the 2018 World Championship in Sheffield, which begins on April 21.
