Rafael Nadal landed the 1,000th singles win of his career as he survived an early scare at the Paris Masters.

Nadal's fellow Spaniard Feliciano Lopez went close to a major upset as the veteran pushed him all the way, but Nadal came through 4-6 7-6 (7-5) 6-4.

After sweeping to French Open glory last month without dropping a set, Wednesday's match marked Nadal's return to action and it took him two hours and 30 minutes to get the job done.

He sits fourth on the list of players with the most wins in the Open Era, behind Jimmy Connors, Roger Federer and Ivan Lendl.

There were also victories for Alexander Zverev, Diego Schwartzman, Milos Raonic and Alex de Minaur. while Daniil Medvedev went through after opponent Kevin Anderson retired due to injury during a first-set tie-break.

Away from clay, Nadal looks vulnerable in Paris

Nadal was imperious at Roland Garros, roaring through the draw on the way to his 13th French Open title.

Across town, at the Bercy Arena, it has been a different story throughout Nadal's career.

The indoor hard-court event is one he has never won and has often skipped, with this just his eighth appearances in the main draw, and this was almost a brief visit as Lopez made a storming start.

Lopez managed what nobody could at Roland Garros by swiping that first set after a break of serve in the opening game of the match, but 20-time grand slam winner Nadal stepped up his game to reach the last-16 stage and chalk up a landmark win.

The 39-year-old Lopez saved five break points in the second set to earn a tie-break, only for Nadal to edge it and then break serve for the first time at the outset of the decider.

With his hard-fought success, Nadal, 34, extended his head-to-head winning record to 10-4 against Lopez, with their rivalry having begun on an indoor carpet court in Basel back in 2003.

Likely challengers come through

German fourth seed Zverev swept to a 6-2 6-2 win against Serbian Miomir Kecmanovic, while Schwartzman swatted away Richard Gasquet, landing a 7-5 6-3 win over the Frenchman.

There was more disappointment for French hopes as Pierre-Hugues Herbert lost 6-4 6-4 to Canadian Raonic, and Russian Medvedev was embroiled in a battle with Anderson when the South African pulled out of the contest.

Sonego's early exit

Lorenzo Sonego arrived in Paris off the back of a successful week in Vienna, where he knocked out Novak Djokovic in the quarter-finals and went on to finish runner-up to Andrey Rublev.

This week will linger less in the memory for the Italian, who went down 6-3 7-5 to De Minaur.
