April Ross and Alix Klineman are on to the beach volleyball semifinals in Tokyo.

The duo sent defending Olympic champion Laura Ludwig and partner Maggie Kozuch home in straight sets on Tuesday in the quarterfinals, winning by scores of 21-19, 21-19.

The win for Ross means that she is the last woman with an Olympic medal left in the beach volleyball pool.

In 2012, she won silver with partner Jennifer Kessy. In 2016, won bronze with Kerri Walsh Jennings.

A win against Switzerland’s Joana Heidrich and Anouk Verge-Depre on Thursday would automatically get both Ross and Klineman at least a silver medal, with the chance to win gold.
