It has taken Australia to put South Africa's performance in their Tri-series match against West Indies in Providence on Friday into context. South Africa shambled to 188 all out and lost by four wickets.On Sunday, also in Providence, an unchanged West Indian team were bundled out for 116 inside 33 overs and the Aussies needed just four balls more than half their innings to win by six wickets.This is not Twenty20, where accidents will happen. This is 50-over cricket on a benign pitch, which makes the comparison as valid as it should be disturbing for the South African fans.So, fasten your seatbelts: South Africa meet Australia tonight. The match will be played in Providence - a word the Merriam-Webster Dictionary defines, in its philosophical sense, as "divine guidance or care".It's too easy to wonder out loud whether South Africa need something like that to get through the game in one piece, not in terms of staying afloat in the Tri-series as much as the bigger picture of the apparently crumbling edifice of a once strong team.AB de Villiers' side will take all this, and more, onto the field with them. Much of that weight will be on the shoulders of the spinners.Twenty-two of the 30 wickets that have fallen in the two matches played so far have been taken by slow bowlers. The trend is unlikely to be bucked tonight.South Africa's most successful bowler on Friday, left-arm spinner Aaron Phangiso, who took 3/40, wasn't complaining."It was a bit dry, not something we usually get in SA," he said. "So it was very helpful." But for now Phangiso, 32, is focused on staying in the team. - TMG Digital..
