SriLanka, May 9 -- British number one Cameron Norrie exited the Italian Open in the second round with a straight-set defeat by Argentina's Thiago Agustin Tirante.

The 17th seed lost 6-3 7-5 to Tirante, who is ranked at a career-best 69th in the world.

Norrie, the world number 19, was playing his opening match after a first-round bye. He was immediately at a disadvantage, losing his first service game as he swiftly trailed 3-0 in the first set, which the unseeded Tirante served out in 34 minutes.

The second set was a tighter affair, with both players holding serve until Tirante broke for 6-5, and the 25-year-old then delivered a match-clinching service game to love.
