Marat Safin came through a marathon struggle with Felix Mantilla to reach the third round of the French Open.
The Russian 20th seed prevailed 6-4 2-6 6-2 6-7 11-9 in an epic match that had to be held over from Thursday in Paris.
Safin twice led in sets, but on both occasions he was pegged back by plucky Spaniard Mantilla, who saved a fourth-set tie-breaker to force a decider.
The crucial break came at 10-9, when Safin finally broke Mantilla's resolve to set up a clash with Potito Starace.
After the match, Safin was scathing of officials after being penalised a point for dropping his shorts during the third set on Thursday evening.
"It just happened. I felt it was a great point for me and I felt
like pulling my pants down," said the 24-year-old, who could also be fined for the incident.
"Nobody complained. I thought it was entertaining and I was
trying to make the game fun.
"There are officials who are trying to destroy the sport. It's
going down the drain. It's a pity that we have these people running
