Snooker World Championship: Ding shows his class to leave Selby with fight on his hands
Defending champion Mark Selby had plenty to think about overnight following an enthralling first session of his Betfred World Championship semi-final with Ding Junhui.
There was little to split the pair at the £1.75m showpiece in Sheffield yesterday before Ding, who lost to Selby in last year's final, won the closing three frames to secure a 5-3 advantage.
They shared the opening four frames of the best-of-33 clash at the Crucible, with Ding twice edging ahead.
The 30-year-old Chinese star cleared up with a break of 76 in the first and then took the third with a run of 84 after Selby had again let him back in.
Selby responded on both occasions, producing an audacious pot on a red on his way to a break of 68 in the second and then falling one point short of a century in the fourth.
The contest became a far more tactical affair following the mid-session interval and Selby edged in front for the first time at 3-2.
The world number one had cruised through to the last four, dropping only 11 frames in comfortable victories over Fergal O'Brien, Xiao Guodong and Marco Fu but, as expected, Ding was proving to be a far more formidable opponent.
He pegged back Selby after another lengthy frame of safety exchanges before runs of 56 and 50 in the seventh saw the world number four restore his lead.
Ding then ensured he would take a slender advantage into today's second session by wrapping up the final frame with the first century of the match (110).
Four-time winner John Higgins holds the initiative in the other semi-final after having the better of a scrappy encounter with Barry Hawkins.
The 41-year-old, playing in the last four at the Crucible for the first time since he last won the tournament back in 2011, leads 5-3 going into today's crucial second session.
