MELBOURNE: Andy Murray’s brave Australian Open run ground to a halt against Roberto Bautista Agut, the Spaniard fending off the fatigued former world number one 6-1 6-7(7) 6-3 6-4 in the third round to advance on Saturday. After back-to-back five-set wins over Matteo Berrettini and Thanasi Kokkinakis, a ragged Murray hung tough against the 24th seed but was gradually worn down over the course of the three-and-a-half hour slog at a floodlit Margaret Court Arena. Murray’s previous match against Kokkinakis, which ended past four in the morning after nearly five hours of play, left him with little sleep, a bad back and a slew of blisters that needed draining from his feet. Between points against Bautista Agut he shuffled around the baseline like a frail senior citizen but when the ball was in play he threw himself around the court to give the Spaniard a proper scare. With the crowd firmly in his corner, Murray broke Bautista Agut in the first game of the fourth set to raise hopes of levelling the match but he ended up squandering a 2-0 lead before dropping serve in the ninth game. The spent Scot soon fired a cross-court forehand long to concede match point and netted a weary backhand return to bow out, triggering manic celebrations by Bautista Agut, who will play American Tommy Paul for a place in the quarter-finals.
