WPBSA Welsh Open: China's Yan & Yu reach quarter-finals ​
[]
At snooker's Welsh Open, China's Yan Bingtao and Yu Delu are both into the quarter-finals. Yan beat Matthew Stevens 4-2, while Yu Delu topped his compatriot Liang Wenbo 4-1. Yan became the youngest player to reach the final of a ranking event when he did so at the 2017 Northern Ireland Open, and the 18-year-old will play Barry Hawkins in the last eight.  
Also in the quarters is five-time world champion Ronnie O'Sullivan who extended his winning streak to 18 frames after back-to-back whitewashes set up a quarter-final with fellow veteran John Higgins.
This is O'Sullivan cruising in the second frame, and this is his opponent Mike Dunn watching helplessly.  
Ronnie would put together runs of 84, 69, 117, and 67 to see off Dunn 4-0 in just 51 minutes to complete his third straight match without dropping a frame. Higgins is also tearing through opponents as the four-time world champion from Scotland dumped Sam Craigie and Nigel Bond 4-0 to reach the quarter-finals.
