Selby shows his mettle at Masters
SNOOKER: World number one Mark Selby produced a superb fightback to book his place in the quarter-finals of the Betfair Masters at the expense of Stuart Bingham.
Selby trailed 5-1 at Alexandra Palace but reeled off five frames in a row to win 6-5 and set up a last-eight clash with former world champion Mark Williams.
After Selby took the opening frame with a break of 63, Bingham assumed command to lead 5-1.
But, Selby found some form and breaks of 57, 86 and 68 got him back on terms as Bingham started to feel the pressure before he wrapped up an unlikely victory.
In the afternoon session, Williams admitted he had dragged opponent Matthew Stevens down to his level before claiming a scrappy 6-4 triumph.
'Irish' Van der Merwe retires
CRICKET: Ireland off-spinner Albert van der Merwe has announced his retirement from internationals.
Born in South Africa, Van der Merwe took 40 wickets for his adopted country at an average of 22.5, including 11-68 against Kenya in Mombasa last year - the best match figures by an Ireland bowler in 40 years.
But he was unable to commit enough time to carry on playing at an international level.
"Retiring has been a difficult decision to make as I feel I still have plenty to offer, but the increased demands as the team became more professional made it very difficult for a part-timer like me," he said.
