(CNN) -- Rafael Nadal is known as an iron man on the tennis tour but even he gets tired. After long semifinal matches in Chennai in 2008, Madrid in 2009 and at the World Tour Finals in London in 2010, fatigue likely played a factor in the Spaniard losing the next day. Nadal was on court for nearly three hours on Saturday against Pablo Andujar at the inaugural Rio Open but this time he recovered to win the finale, defeating tricky Ukrainian Alexandr Dolgopolov 63 76 (3) for a 43rd title on clay and 62nd overall. The latter tally placed him in a tie for seventh with Guillermo Vilas.
