Tennis: Third seed Lleyton Hewitt became the biggest casualty of the Australian Open when he was upset 6-4 6-4 6-7 6-2 by bitter Argentine rival Juan Ignacio Chela in the second round.
Unseeded Chela triumphed in an unexpectedly flat encounter against world number six Hewitt, who needed treatment including pain killers for a foot injury in the third set but was still able to fight back and force a tiebreak, which he won 10-8.
Chela dragged Hewitt into long rallies and benefited from points gifted by wild forehands from the Australian, who was last year's losing finalist. Hewitt also struggled with his serve.
The match failed to produce the expected fireworks after last year's spiteful third-round clash between the pair, when Chela was later fined for spitting in Hewitt's direction.
