ROME, May 7 (Reuters) - Rafael Nadal's bid to win a fourth straight Rome Masters title stumbled at the first hurdle when the Spaniard lost 7-5 6-1 to compatriot Juan Carlos Ferrero on Wednesday.

It is only the second time in his last 104 games that world number two Nadal has lost on clay including his defeat by Roger Federer in the final of last year's Hamburg Masters.

Ferrero, the unseeded 2001 champion, will meet the winner of the match between Britain's Andy Murray and Switzerland's Stanislas Wawrinka in the third round.

The unseeded Ferrero consistently put number two seed Nadal under pressure in the first set.

A venomous serve helped the Spaniard save a set point in the 10th game but Ferrero got his reward two later, clinching the crucial break with a fine cross-court backhand.

Nadal had also been let down by some uncharacteristic unforced errors, with over-hit forehands costing him three set points in the ninth game of the first set.

Ferrero grew in confidence and took the second of two break points in the fourth game of the second set, after Nadal saved the first with a brave drop shot.
