Mphela brace sinks lacklustre Burkinabe
Captain Siphiwe Tshabalala was also on target for Bafana Bafana as they warmed up for a 2012 Africa Cup of Nations qualifier in Niger next month by outplaying the Stallions.
Mphela has scored 21 goals for his country and lies third behind active Benni McCarthy (31) and retired Shaun Bartlett (29) on the all-time South African scorers list. Tshabalala, captain in the absence of injured Tottenham Hotspur midfielder Steven Pienaar, scored at international level for the first time since grabbing the opening goal of the 2010 FIFA World Cup South Africa™ against Mexico.
Resurgent South Africa have won six and drawn two of nine matches since local coach Pitso Mosimane replaced Brazilian Carlos Alberto Parreira after a first round exit last year from the FIFA World Cup.
"We were good in all departments against opponents who brought many European-based players and deserved our emphatic victory," said Mosimane.
South Africa were immediately on the front foot and went ahead on 14 minutes when 26-year-old Mphela from the Pretoria-based Mamelodi Sundowns club lifted a free-kick over the wall and past teenage goalkeeper Germain Sanou.
Neat, one-touch passing after a throw-in created a chance for Tshabalala five minutes later and he made no mistake with a low shot across the goalmouth and into the far corner of the net.
The game ceased to be a contest seven minutes into the second half when Mphela beat an offside trap and gave France-based Sanou no chance with a low shot that flew in off the far post.
