Rafael Nadal was forced to come from a set down to beat Kevin Anderson and book his spot in the quarter-finals of the Paris Masters.
Nadal needed two hours and 27 minutes to see off the challenge of Anderson 4-6, 7-6(6), 6-2 and set up a meeting with Stanislas Wawrinka.
Anderson grabbed the early advantage with a break in the third game of the match, and the big-serving South African refused to relinquish his advantage as he served out the set 6-4.
The second set was a tightly-contested battle, with Nadal winning 92 percent of points on his first serve to ensure he remained in the encounter, with neither player offering up a break point opportunity in the set.
Nadal came up trumps when it mattered tough, edging the tiebreaker 8-6 to force the match into the decider.
Having come so close to wrapping up the match, Anderson was slow off the mark in the third set and paid the price, with Nadal securing a break in the first game of the set.
The slip up appeared to deflate Anderson further, with the world number 12 surrendering his serve once more in the seventh game as Nadal took the decider 6-2.
