LLEYTON HEWITT breathed a massive sigh of relief after battling past American James Blake.
Australia's Hewitt lost the first set and was a set point down in the second before winning the tie-break.
Blake, who broke his neck last year, injured his hand in a dive on the final point of the tie-break and was never able to reproduce his best form.
Hewitt won 4-6, 7-6, 6-0, 6-3 and now faces Juan Ignacio Chela.
Blake said: "I look at the big picture. If I had hit my head differently, I could have been paralysed. Being in a tiebreaker with one of the best players in the world is what I missed."
