Venus and Serena Williams will face off against each other on Monday for a fourth-round match at Wimbledon. But that didn't stop them from a little playful banter in the lead up to the match on Sunday, as they engaged in a back on forth on Instagram.
First, came this post from the younger Serena, 33, who leads her older sister, Venus 14-11 in their match ups.
Venus, 35, responded with a garden snap.
Hey, what's a sister for?
Tomorrow's match begins at 8 a.m. ET and will be the first time the sisters have played each other in a Grand Slam since Wimbledon in 2009.
