As the World Superbike season trips into the mid-way point of the season, Leon Haslam has extended his lead at the top of the standings with a fine win and third place finish at Kyalami.

Going a long way to halting Max Biaggi's momentum from his double win at Monza, Haslam's stylish victory in the second race has put a small, but significant bit of air between himself and the Aprilia rider to the tune of 15 points.

The results also see Suzuki go back past Aprilia in the battle for this season's manufacturers' trophy, the two now fairly clear of Ducati in third position.

Back to the riders' standings and there have been no movements inside the top seven, while even Jonathan Rea and Carlos Checa continue to be tied in third position after picking up a second and fifth place finish each.

A couple of middling top ten results means James Toseland is now arms' length adrift, but comfortably up on Noriyuki Haga, whose sole tenth place finish means Troy Corser is just one point off from making it six different manufacturers inside the top six positions.

The day's big mover is Michel Fabrizio, courtesy of his win in the first race, the Italian edging back into the top ten in eighth, ahead of Cal Crutchlow, who rises a position to ninth. Going the other way, a race two retirement sees Leon Camier down to tenth again, while Sylvain Guintoli has now dropped outside the top ten.

Further back, it was a dismal day for Max Neukirchner, his two failures to score meaning he is now a lowly 18th in the overall standings, behind the likes of Ruben Xaus, Tom Sykes, Lorenzo Lanzi and Luca Scassa.

Meanwhile, the standings have swelled to include 25 riders after wild-card Sheridan Morais got on the board with a 13th position.
