David Ferrer became only the fourth active player to record 600 career wins when he cruised past Thomaz Bellucci 6-1, 6-2 to reach the Valencia semi-finals on Friday.
The world number five delighted his home town crowd with victory in just 67 minutes as he goes on to face Andy Murray, a rival for a place in the World Tour Finals, on Saturday.
Ferrer joins Roger Federer (986 wins), Rafael Nadal (706) and Lleyton Hewitt (611) in the modern era 600-win club.
Murray earlier rallied from a set down to reach the semi-finals with a 6-7 (3/7), 6-4, 6-4 win over South Africa's Kevin Anderson.
Murray is hoping to boost his chances of a seventh consecutive appearance in the World Tour Finals in London next month.
A horrible service game that included two double-faults put Murray in trouble in the first set as the big-serving Anderson broke to love to lead 4-3.
The two-time Grand Slam champion repaired the damage by breaking straight back in a marathon 22-point game, but Anderson proved too strong in the tie-break as Murray's service faltered once more.
After an early exchange of breaks in the second, it was Murray who took control with some characteristic chasing from well behind the baseline before passing Anderson at the net to break for a 5-4 lead.
The Scot served out for the set and broke through again at the beginning of the decider with a lovely lob for which Anderson had no answer
And despite blowing three match points when serving for victory, Murray sealed his 16th win in 18 matches when Anderson found the net on his fourth match point.
