Top seeds the Bryan brothers have reached the quarter-finals of the men's doubles thanks to a hard-fought victory over Russia's Nikolay Davydenko and Mikhail Youzhny.
With both teams dropping a service game each in the opening set, the American duo came out 8-6 winners after an up-and-down tie-break.
Both pairings were again evenly matched in the second, but the brothers stormed the tie-break 7-1 to progress through to the last eight.
They will now face the Israeli team of Jonathan Erlich and Andy Ram with a semi-final place at stake.
