In-form fifth seed Juan Martin del Potro has been a shock elimination from the Australian Open.
The Argentine fell to unheralded Spaniard Roberto Bautista Agut 4-6 6-3 5-7 6-4 7-5.
Del Potro, who crushed Bernard Tomic to win the final of the Sydney International earlier this month, was outlasted by world No.62 Agut.
Their second round match didn’t finish until just before 1.30am (AEDT) on Friday.
