Serena Williams has claimed that she feels "no pressure" in her bid to win a 22nd Grand Slam title at the US Open.
The 33-year-old beat Madison Keys in straight sets at the Arthur Ashe Stadium to set up a last-eight clash with sister Venus Williams.
However, Serena was quick to pay tribute to her sister's performances at Flushing Meadows, suggesting that Venus "is playing great".
The six-time US Open champion also made light of their forthcoming encounter, saying "at least a Williams will be in the semi".
Venus beat Estonia's Anett Kontaveit in less than an hour to reach the last eight.
