Leander Paes and his Czech partner Radek Stepanek suffered their first defeat at the year-end ATP World Tour finals, losing their second Group B match to David Marrero and Fernando Verdasco at the O2 Arena in London on Wednesday.
The seventh seeded Indo-Czech pair was beaten 4-6, 6-7(5) in 89 minutes.
Paes and Stepanek, the US Open winners, now have to beat Marcel Granollers and Mark Lopez to make it to the next stage without any favour from the other teams.
They had beaten Alexander Peya and Bruno Soares in their opening match on Tuesday.
Following Wednesday’s victory, their second in as many matches, Marrero and Verdasco became the first team to qualify for the semi-finals.
The top two teams in each group qualify for the semi-finals.
Marrero and Verdasco mixed net and baseline play to negotiate a break of Stepanek’s serve to 30 for a 5-4 lead in the first set, Verdasco clinching the 34-minute opener with a hold to love by finishing with an ace.
Paes dropped his serve to 30 in the opening game of the second set, but the Indian-Czech team recovered from 0-2 by winning three straight games.
Both teams completed routine service holds as the set went to the tie-break.
Verdasco served for the set at 6-4, but hit a double fault. His second serve hit Marrero on the shoulder and both players turned to one another and smiled.
Marrero sealed victory on their second match-point when he hit a powerful forehand to the feet of Paes.
