Rafael Nadal narrowly escaped a first-round defeat against Lukas Rosol of the Czech Republic at the Swiss Indoors Basel on Monday.
Rosol has history with the Spaniard, having handed him a memorable second-round defeat at Wimbledon three years ago, and he looked set for a repeat of that performance after sailing through the first set 6-1 and going 2-0 up in the second.
Nadal's game has been on the up in recent weeks, however, and he was able to hit back by breaking twice late in the second set to even the scores before seizing another break early in the third for a 3-0 lead.
But it wouldn't be quite that simple for Nadal, as Rosol responded with a break of his own to get it back to 4-4.
Both players held serve from there to force the tie-break, and even though Rosol grabbed a 4-2 lead, Nadal was able to produce one big final push, winning the last five points in a row for a hard-fought 1-6 7-5 7-6 (7-4) victory after two hours and 18 minutes.
On a day of comebacks, Frenchman Andy Mannarino also battled back from a set down to beat Viktor Troicki 4-6 7-5 7-6 (7-3), while Austrian Daniel Thiem did the same against Robin Haase, eventually winning 0-6 7-6 (7-5) 7-5.
