Andy Roddick on Sunday claimed his third straight Stella Artois Championship title with a straight-sets victory over Ivo Karlovic.

Roddick won 7-6 7-6 after one hour and 20 minutes of a serve-dominated battle to join John McEnroe and Lleyton Hewitt as the only players to win a hat-trick of titles at Queen's Club.

"It feel great," said the world number four. "I never would have predicted it three years ago but I'm very happy.

"My game on grass has improved a lot. When I won here the first time I had never really had any great results on grass.

"Two or three years later it's probably up there with my favourite surfaces.

"It has been a complete 180 and I feel really good at the moment."

The second seed had warned the final could be "pretty boring," to watch and sadly he was absolutely right as the duo simply traded thunderous serves at each other.

Karlovic, the 6ft 10in Croatian who famously beat defending champion Hewitt in the first round at Wimbledon in 2003, saved three break points in the second game of the match - the only chances for a break throughout the contest.

Roddick, who lost in the Wimbledon final last year to world number one Roger Federer, praised Karlovic's serve as "the biggest weapon in tennis," adding: "There were a couple of times I guessed right way and was fully extended, diving to that side and still missed it by two feet.

"It's not so much the pace or the spin. He hit a couple of aces out wide that were a quarter of the way up the service box and when you make contact with them it's above your head. It's not like something I've seen before."

As expected the result came down to a handful of decisive moments, the first coming in the opening tie-break when Roddick, having squandered his first set point, converted his second with a service winner.

And the next did not arrive until the first point of the all-too predictable second set tie-break, Roddick producing a backhand winner which clipped the outside of the line before consolidating the mini-break with back-to-back aces.

The 22-year-old American has yet to decide whether to play a number of exhibition matches next week or concentrate on practising at Wimbledon, but is content with his preparations so far.

"I feel pretty comfortable on the grass and I'm looking forward to Wimbledon," added Roddick, who has now won his last 15 matches at Queen's Club - an impressive statistic still dwarfed by Federer's 29-match unbeaten run on grass after the Swiss star also successfully defended his title at Halle.

"It can only help that I've played a couple of serve and volleyers and guys who are a little bit craftier this week, I've seen a lot of different tennis this week."
