ATP World Tour Finals: Federer-Nadal XXVI

Roger Federer and Rafael Nadal will meet for the 26th time of their careers, the fourth time in 2011, on Tuesday at the ATP World Tour Finals. Nadal has won all three of their previous meetings in 2011, on the hard courts in Miami, on the clay courts of Madrid and in the 2011 Roland Garros final. Nadal now leads their career head-to-head by a dominating 18-7.

This latest meeting is on an indoor hardcourt, when Federer is currently on a 13-match winning streak while Nadal needed a 3rd set tiebreak to escape with a win against Mardy Fish two days ago. They are meeting in the round-robin section of the year-end championships. Last year, Federer defeated Nadal on exactly this court in the final match of the year. I suspect that result will be repeated again on Tuesday.

PREDICTION: Federer.
