WIMBLEDON, England (AP) - Ivo Karlovic accused the line judges at Wimbledon of favoring British star Andy Murray and said he felt ``cheated'' after they called foot-faults against the hard-serving Croat on Centre Court.

Murray beat Karlovic 7-5, 6-7 (5), 6-2, 7-6 (4) Thursday, with the Croat being called for foot-faults on key points.

``I don't know what to say, but it was a little bit outrageous,'' Karlovic said. ``I mean, what is this? Is it Davis Cup or is it Wimbledon? After this match, the whole credibility of this tournament went down for me.''

One foot-fault was called in the final tiebreaker, while several others were made in the later stages of games. The 6-foot-10 Karlovic said he moved his feet back further behind the baseline to avoid more foot-faults, but they kept being called.

``In my whole life, ever since I was 8 years old, whole life I didn't do this many foot-faults. It was like 11,'' he said. ``So it was outrageous, outrageous. It's Wimbledon, Centre Court, and they do this. ... I feel cheated.''

Murray, from Scotland, is always backed by a raucous home crowd on Centre Court, as he carries the nation's hopes of becoming the first British man to win Wimbledon since Fred Perry in 1936.

``Right now I'm angry about it ... because I don't expect it here,'' Karlovic said. ``Even though it is against (a British) guy who they always want to win, but I don't expect it here.''

Murray acknowledged there was an unusually high number of foot-faults called, but said he wasn't sure whether they were correct.

``You can only look on the TV,'' he said. ``And if he wasn't foot-faulting then he has a right to be upset, because there was a lot of them. But if he was, then you can't do it. It's not allowed.''

While Karlovic won the second-set tiebreaker, he said the foot-faults had a decisive effect on the final result.

``You do the calculation. If these 10 points, I win, who would have won?'' he said. ``You do the math.''
