LONDON (AP) — Former champion Marin Cilic was upset by Marinko Matosevic of Australia in the opening round at the Queen's Club on Tuesday.
The Croatian won the grass-court title in 2012 and finished as runner-up to Andy Murray in 2013, but was beaten 6-4, 6-4, with a single break of serve in each set deciding the outcome.
Matosevic, who reached the final of a grass event in Nottingham last week, saved a break point in each set on his way to victory, and said he was unconcerned at having lost all three of their previous meetings.
"I feel like I have been really close to beating him all previous times," said Matosevic, who was coached by Australian great Mark Woodforde. "Australian Open I played him, had 11 break points. Didn't take any. Monte Carlo just a month and a half ago, I was a break up in the third and lost to him."
Cilic blamed a lack of grass-court preparation for his defeat.
"I came this year a bit later than usual," he said. "Just maybe I felt I didn't adjust myself too good on grass yet. In the movement I felt it the most. I slipped also a couple of times, and then I was running a little bit too careful on some balls.
"But Marinko played really well, very consistent from beginning till the end. He wasn't giving me too many opportunities."
In second-round matches, second-seeded Tomas Berdych struggled to a 7-6 (3), 5-7, 6-4 win over Australian qualifier James Duckworth, and fourth-seeded Grigor Dimitrov of Bulgaria defeated British wild card James Ward 7-5, 6-3.
