Venus Williams is prepared to end her sister's attempt at a first calendar Grand Slam when she meets Serena in the US Open quarter-finals.
The sisters will play each other for the 27th time when they open the night session at 00:00 BST on Wednesday.
Serena, 33, has not lost a Grand Slam match since Wimbledon 2014 and hopes to win the first calendar Slam since 1988.
"No-one is out to be a spoiler, but at the same time you're focused on winning your match," said Venus, 35.
But she added: "I think people love to see history being made."
