Madison Keys and Jessica Pegula have an extra task before their Australian Open fourth-round clash: recording their podcast together. The American duo, who co-host *The Player's Box*, both won straight-set third-round matches on Saturday. Keys defeated Karolina Pliskova 6-3 6-3, while sixth seed Pegula beat Oksana Selekhmeteva 6-3 6-2.

Their on-court rivalry won't affect their off-court friendship, according to both players. Keys, the defending champion, said they'll remain friends until they walk on the court, then become fierce competitors. The pair have already discussed potential forfeits for the loser of their Monday match, with Pegula joking about trash-talk segments and Keys refusing to eat Pegula's apple pie with cheese.

This marks the second time Pegula faces a friend at this tournament, having partnered with McCartney Kessler in doubles before defeating her in the second round. Regardless of Monday's result, Keys believes their friendship will endure. The winner will likely face fourth seed Amanda Anisimova in the quarter-finals.
