ACAPULCO (Reuters) - A dominant Rafa Nadal dismantled fellow Spaniard David Ferrer 6-0 6-2 on Saturday to win his second Mexican Open championship and continue his successful comeback from a long injury lay-off.

The former world number one charged out of the blocks by winning the first eight games and ended top seed and three-time defending champion Ferrer's 19-match winning streak at the clay court event.

Nadal, the 2005 champion, returned to the tour last month after a knee injury sidelined him for more than seven months.

Second seed Nadal pocketed $291,800 in prize money and celebrated his 38th clay-court title following his win two weeks ago at the Brazil Open.
