British number one Cameron Norrie fell to an early exit at the Monte Carlo Masters as he lost to Francisco Cerundolo 6-3 6-4 in the first round.
The world number 13 was beaten by 24-year-old Cerundolo on the Mediterranean clay.
Norrie looked unsettled all through and made 18 unforced errors compared with only eight winners as Cerundolo gained the decisive break in the ninth game of the second set when Norrie netted a forehand.
Norrie started the season with a run of 21 wins from 25 matches but also lost his opening match at the Miami Open last month when he was defeated by France’s Gregoire Barrere.
