Canada will host their Davis Cup World Group playoff tie in September because opponent South Africa can’t afford to. Tournament organisers approved Tennis South Africa’s request for the switch and says Canada will stage the match-up from September 14-16. The venue hasn’t been decided. TSA says “current economic conditions” mean it won’t be able to organise the tie. The shift could yet favour South Africa, with leading player and No.35-ranked Kevin Anderson likely to be in North America for the US Open, which ends on September 9. Anderson has recently skipped Davis Cup duties at home. Canada captain Martin Laurendeau says his players are “thrilled” to be able to play in front of a home crowd. The winner earns a place in the top World Group in 2013.
