Paris: Roger Federer moved clear of Jimmy Connors on Wednesday for most matches won at the four Grand Slam championships in the Open Era.

Federer improved to 234-35 lifetime after he battled to beat World No. 92 Adrian Ungur of Romania 6-3, 6-2, 6-7(6), 6-3 at Roland Garros for a third round match against Slovakian Martin Klizan or Nicolas Mahut of France. Federer saved two set points at 4-5, 15/40 in the third set, then he squandered two match point opportunities at 6-4 in the tie-break with mistimed groundstrokes.

He lost four straight points and a net-rushing Ungur clinched the 48-minute third set when he rushed Federer into a backhand error. Federer is now 9-6 this year in tie-breaks. Ungur began to tire at the start of the fourth set that saw Federer take a 3-0 lead. It proved to be enough and the 30-year-old Federer improved to a 33-4 record on the season with victory in just just over two hours and 30 minutes.

Meanwhile seventh seed Tomas Berdych dropped just seven games against France's Michael Llodra for a 6-2, 6-3, 6-3 victory in one hour and 41 minutes. Berdych recorded his first win over Llodra since June 2007 at Wimbledon. The 26-year-old Czech, who reached the 2010 semi-finals, now has a 348-200 match record.
