Ghana defeated Mali 2-0 on Saturday night to leave Group D at the Africa Cup of Nations wide open after Guinea earlier hammered Botswana 6-1.
The 2010 World Cup participants are now top of the group on six points from two matches, while Guinea and their opening-day conquerors Mali are on three points, with all three teams still in the reckoning to advance to the knockout stage.
To add to the suspense, even point-less Botswana are not mathematically out of contention.
On Wednesday, Mali will battle Botswana in Libreville and Ghana take on Guinea in Franceville in the final throw of the Group D dice.
Star striker Asamoah Gyan opened the scoring for Ghana in the 63rd minute with a well-strck free-kick from the edge of the Mali box after Andre Ayew was brought down by Bakaye Traore.
‘Baby Jet’ Gyan had struggled with an ankle injury leading up to the game but Ghana coach Goran Stevanovic insisted on fielding the UAE-based star and it paid handsome dividends.
