NEW YORK (CBSLA.com) — Venus Williams reached the quarterfinals at the US Open for the first time since 2010 by beating Anett Kontaveit in two sets on Sunday.
Williams beat the 19-year-old Estonian in just 50 minutes, winning the first set 6-2, and the second set 6-1.
The next match that would take place at Flushing Meadows was between her sister, Serena, and Madison Keys.
Keys was no match for the younger Williams sister, as she took care of Keys in just two sets, winning each set 6-3.
The Williams sisters will now face off for the 27th time in their careers.
Serena has a career record of 15-11 against her old sister Venus.

The only thing that is certain at this point in the 2015 US Open is that there will certainly be one Williams sister in the semifinals.
Serena Williams is looking to complete the true Grand Slam by winning each major tournament in the same calendar year.
She has already won the French Open, Australian Open, and Wimbledon in 2015.
The last women to win the true Grand Slam was Steffi Graf in 1988.
