MELBOURNE, Australia - Gabriel Diallo of Montreal battled for more than four hours, but his conditioning paid off as he outlasted Luca Nardi in a five-set men's singles marathon to advance to the second round of the Australian Open on Monday.
The 23-year-old Canadian prevailed 6-7 (1), 7-6 (3), 5-7, 6-1, 6-2 over the 21-year-old Italian, who appeared to run out of gas in the fourth set.
Diallo had 21 aces in the four-hour, nine-minute match, while Nardi managed nine.
While there wasn't much to separate the players in the first three sets, Diallo took over in the fourth as Nardi had 13 double faults and saw his first serves drop in winning percentage.
Diallo finished with more unforced errors (8-5), but did better on break points, winning seven of 16 compared to Nardi's four of 15. Diallo won 66 points off his return, compared to his opponent's 57.
Diallo will now face the 31st-seeded Francisco Cerundolo of Argentina in the second round.
