Updated / Saturday, 1 May 2021 08:49 Mark Selby and Stuart Bingham play to a finish from 2.30pm on Saturday afternoon Mark Selby was warned for slow play as Stuart Bingham won five frames in succession to wrest control of their World Snooker Championship semi-final at the Crucible. Referee Ben Williams intervened to tell Selby to "think about taking a stroke" after the three-time champion took over three minutes deliberating during a 19th frame that ticked over the one-hour mark. Bingham started the evening with a 131 clearance then made a valiant attempt at a maximum break, before ultimately fashioning a 13-11 advantage heading into their final session on Saturday afternoon.
