We enjoy a punt here at BackPageLead and have been known more than once to scream ''rigged'' in jest as our well-backed favourite jogs in arse-first or misses a 15-metre shot for goal on the siren. Normally we'd put it down to the glorious unpredictability of sport. We might even make a mental note never to tip horse X or team Y again and move on.

That mental note has just been written for ATP players, Janko Tipsarevic, of Serbia, and Argentina's Horacio Zeballos.
