Rafael Nadal beat fellow Spaniard David Ferrer 7-5 6-2 to equal Andre Agassi's record of 17 Masters titles in a rain-delayed final in Rome, BBC reported.
Ferrer saved five break points in the early stages but a persistent Nadal broke the world number 17's serve late on to edge the opener.
A second downpour followed when Nadal was a break up in the second at 2-1.
But neither the weather or Ferrer could avert the world number three's march to victory as he wrapped up the set 6-2.
