Rafael Nadal became the fourth player to record 1,000 ATP Tour wins with victory over fellow Spaniard Feliciano Lopez at the Paris Masters.
American legend Jimmy Connors leads with 1,274, followed by Nadal's long-time rival Roger Federer (1.242) and Czech great Ivan Lendl (1,068).
The feat comes a month after Nadal won his 20th Grand Slam, matching Federer's record, with a 13th French Open title.
Nadal will play either Borna Coric or Jordan Thompson in the last 16.
The Spaniard was presented with a glass trophy with '1,000' embedded on it after his landmark victory.
It has been a remarkable career for the Spaniard, who turned professional in 2001 and won his first ATP Tour match in 2002 when he defeated Paraguay's Ramon Delgado in the first round of the Mallorca Open.
He remains 68 wins shy of Lendl, which is within his reach but whether he manages to eclipse Federer and Connors remains to be seen.
British three-time Grand Slam champion Andy Murray has won 676 ATP matches.
