MIAMI (AFP) Sixth-seeded American Andy Roddick ended the giant-killing run of Czech Tomas Berdych to secure the Miami ATP Masters 1000 title Sunday. One break of serve in each set was enough for Roddick, who didnt face a break point in the entire match which he won 7-5, 6-4. Its a surprising stat, especially on one side, Roddick said. It was real rough with the sun on first serves youre having to adjust your toss and seeing spots on the first ball. I think thats what helped me break in the first set, you know, but I think it was maybe a little bit of an advantage that I played out there in that time slot a couple times. His victory brought an end to the impressive run of the 16th-seeded Berdych, who had survived a match point to shock world number one Roger Federer in the fourth round. He was really good today, Berdych said. He was really strong, serving well. I was really looking for maybe to get one chance - maybe one is enough. But he held pretty well. I didnt get any chance in the whole match during both sets, so thats well-played for him. Roddick, who beat world number four Rafael Nadal in the semi-finals, added a second Miami title to the one he captured in 2004. In addition to a superb serving performance that included 13 aces, Roddick used a canny baseline game - varying the pace of his groundstrokes to keep Berdych on the hop. Roddick, who dropped only two service games in the tournament, surrendered just seven points on his serve in the second set. He gave himself his third match point when he ended an exchange at the net with an overhead, and Berdych hit a backhand into the net to finish it off. The Czech had saved two match points in the previous game. Roddick improved to 26-4 in 2010, the best match record on the mens tour. The American claimed his first ATP 1000 title since Cincinnati in 2006, and it came two weeks after his runner-up finish in the first of the prestigious events in 2010 - at Indian Wells in California. Obviously its a big title for me, Roddick said. I felt a little bit of pressure to win this one, because I had a pretty good opportunity in Indian Wells and didnt come through there. I think just the last month has been real good for me, he added. Ive played well on the big moments. Havent had an off day mentally. Ive been able to execute. Ive been able to have a game plan and execute it regardless of what kind of shots it takes. Its all good, its all encouraging. Roddick was pleased that he was able during the week to find different ways to win. His methodical approach against Berdych was far from his risky, aggressive strategy against Nadal. Against Rafa, when you get two feet under you and youre not being bullied from the baseline, its time to take some cuts, Roddick said. With Tomas I can get away with my slice a little bit more. I can get away with changing paces a little bit more without the angles of the court being utilized as much. He hits the ball straight through a little bit more, so I can kind of rely on legs a little bit more without the court growing this way and becoming tougher. Overall, Berdych said, he was satisfied with his tournament. Well, not as satisfied as I would be if I were sitting here as a winner, he admitted. But Im happy for this two weeks, 10 days, that I played a couple of really good matches. Roddick can emulate Agassi, says coach Stefanki Andy Roddick could emulate Andre Agassi and enjoy his greatest success in the latter years of his career, his coach Larry Stefanki said after watching the American win the Sony Ericsson Open on Sunday. Stefanki, who guided Chilean Marcelo Rios and Russian Yevgeny Kafelnikov to world number one ranking, has been working with Roddick over the past year and believes that the big server has his best years ahead of him. I think this is still the infancy, I really do, I think he could be similar to Agassi where his best years are from 27 onwards, he told reporters. I have seen it done before. I think he was very raw and his game is starting to come to where it is not hit and miss. Agassi won five of his eight grand slam titles after his 29th birthday. So far this year Roddick has won the Brisbane Open and was the beaten finalist at Indian Wells as well as triumphing for the second time at Key Biscayne. Despite possessing a tremendously powerful serve, Roddick has been something of an underachiever as he won his solitary grand slam at the 2003 U.S Open. But Stefanki believes Roddick now has a more diverse set of skills at his disposal. He has a lot of things to fall back on to win when he is not playing great, he does have the best serve in the game at the moment, day in day out, but if you add all the other components, the slice and so on, it puts him in a different echelon, he said. As well as the technical adjustments that needed to be made to Roddicks game, Stefanki said weight loss, a better tactical approach and reduced off-court stress have been key elements in the players rise. When you see a guy with a weapon like Andy has and so raw in every other aspect except perhaps the forehand, but not really know what his game plan is going to be... I think there has been a maturing, his nervous system is calmer now and when you have control over your game and your body. said Stefanki. The coach said Roddick has also changed his diet ditching his junk food habits for more organic options, helped by his swimsuit model wife Brooklyn Decker. I told him 'If you want to get faster, you have to lose weight, added Stefanki, who began his career working with John McEnroe. You are working five hours a day and re-polluting your body. Now he still eats a lot but he eats the right stuff. Roddick said he was delighted with his relationship with his coach, who quickly laid down the ground rules. I think he wanted to run things and I was more than okay with that, thats what I wanted. I wanted the guidance. Im not going to pay a guy to be my coach and then tell him what to do. You would be surprised how prevalent that is in tennis. Its a great mix. I love his tennis IQ. I like his energy. I dont know if Ive ever seen him stressed out unless were late for a tee time. The tennis side of it works and the personality side of it works. So I think were in a good spot, he said.
