Tennis powerhouses Italy and the United States are once again through to the United Cup quarter-finals after joining Kazakhstan, China and defending champions Germany in the last eight.
Flavio Cobolli dug deep to claim a 6-3 6-7 (8-10) 6-2 upset win over France's Ugo Humbert in Sydney to ensure Italy's progression before world No.4 Taylor Fritz outclassed Borna Coric 6-3 6-2 in the opening rubber of Team USA's tie with Croatia in Perth.
Team Italy needed to win just one match in Tuesday's clash at Ken Rosewall Arena to advance, and Cobolli did just that on New Year's eve.
