Melbourne - Belgium's David Goffin ended Ivo Karlovic's record-breaking tournament with a straight-sets win to reach the fourth round of the Australian Open on Saturday.
Goffin had few problems against the weary 21st-ranked Croat, winning 6-3, 6-2, 6-4 in one hour, 28 minutes and will face either Dominic Thiem or Benoit Paire in the last 16.
Karlovic, at 37, was feeling the effects of Tuesday's tournament-record, 84-game victory over Horacio Zeballos when he prevailed 22-20 in the fifth set.
The 11th-seeded Goffin broke Karlovic's serve four times and did not have a break point on his own serve as he reached the round of 16 for the second straight year in Melbourne.
The towering Karlovic finished the tournament with a total of 119 aces -- including 75 in his epic duel with Zeballos, another tournament record.
