My fave tennis playing siblings made it to the quarterfinal round of the 2015 Australian Open and if they made it through their respective matches, would play each other in the semifinals with a Aussie Open finals slot on the line.
While Serena handled her business and took out 2014 Australian Open runner up Dominika Cibulkova in straight sets.6-2, 6-2, to move on to the semifinals, unfortunately that wasn't the case for Big Sis.
Venus came out flat against American teen phenom Madison Keys and lost in three sets 3-6, 6-4, 4-6 despite Keys suffering a left thigh injury that necessitated a medical timeout in the second set.
It is the 19 year old Keys who will face the world's number one ranked player for a spot in the final against the winner of the all-Russian Ekaterina Makarova - Maria Sharapova semifinal.
Despite Venus' time in Melbourne being done, Serena is still alive for her fifth Australian Open title, her first since 2010 and her 19th Grand Slam title overall.
