London (AP): Shane Warne is set to retire from first-class cricket after announcing that he won't be taking up his contract to captain English county side Hampshire this season.

The former Australia legspinner retired from Test cricket in 2007 as the sport's leading wicket taker and had been set to return to Hampshire after playing in the Indian Premier League.

But Warne, who was bought for $ 450,000 by the Rajasthan Royals in this month's IPL player auction, has decided against the move so he can concentrate on a poker career and his children.

Warne finished his career with a world record 708 Test wickets and more than 1,000 in the international arena, although his Test mark was eclipsed by Sri Lanka offspinner Muttiah Muralitharan in December.

He wound up his Test career with a 5-0 Ashes series sweep of England, 14 years after his first ball in the biennial series - the "Ball of the Century" to bowl Mike Gatting in England in 1993 - launched him to international fame.
