PARIS — When Gilles Simon faces Roger Federer on Sunday in the fourth round of the French Open, Simon will have multiple weapons at his disposal — his speed, his signature two-handed backhand down the line and his world-class ability to absorb world-class power and snuff out attacks that would sink less resilient men.PARIS — When Gilles Simon faces Roger Federer on Sunday in the fourth round of the French Open, Simon will have multiple weapons at his disposal — his speed, his signature two-handed backhand down the line and his world-class ability to absorb world-class power and snuff out attacks that would sink less resilient men.

Tennis has long been slow to embrace the game-film culture pervasive in other professional sports. But that is changing. Tennis Australia, the governing body of the sport in Australia, now has an extensive video performance analysis unit that can deliver up-to-date footage and pattern breakdowns on future opponents to its players, whether they are playing in Wimbledon or in a challenger in Tashkent, Uzbekistan.Tennis has long been slow to embrace the game-film culture pervasive in other professional sports.

“They don’t have to go to YouTube anymore, or at least not very often,” Darren McMurtrie, who runs the program, said in an interview in Melbourne, Australia.“They don’t have to go to YouTube anymore, or at least not very often,” Darren McMurtrie, who runs the program, said in an interview in Melbourne, Australia.
“You can use it for all sorts of things, and I think it’s been very useful,” said Samantha Stosur, a former United States Open champion and Australia’s top female player, who has made extensive use of the detailed statistics and curated video clips.“You can use it for all sorts of things, and I think it’s been very useful,” said Samantha Stosur, a former United States Open champion and Australia’s top female player, who has made extensive use of the detailed statistics and curated video clips.

Video analysis is also being used more by private coaches, including Jan De Witt, the German coach whom Simon, a top-20 player, hired in April in part because of his relentless tactical focus.Video analysis is also being used more by private coaches, including Jan De Witt, the German coach whom Simon, a top-20 player, hired in April in part because of his relentless tactical focus.
“I chose Jan because I think he can make me very comfortable with my choices,” Simon, a Frenchman, said in an interview after his five-set victory over Sam Querrey in the third round. “I make a lot more choices on the court than most of my opponents in terms of tactics and strategy. I didn’t play the same in my first couple of rounds as I played against Sam, whereas Sam played much more the same style against everyone.“I chose Jan because I think he can make me very comfortable with my choices,” Simon, a Frenchman, said in an interview after his five-set victory over Sam Querrey in the third round. “I make a lot more choices on the court than most of my opponents in terms of tactics and strategy.

“He has the weapons he’s going to use — his serve, his forehand. Most players are very focused on what’s happening with themselves, on their side of the net. I’m much more focused on what’s happening on the other side of the net. So the tactics are very important to me, and Jan is very good with this, especially with the help of the video.”“He has the weapons he’s going to use — his serve, his forehand.

Simon said De Witt’s video had been particularly useful before his match against third-ranked Andy Murray in the Round of 16 in Madrid in May. Murray had dominated Simon in the past, but Simon pushed him in Madrid, losing in a third-set tiebreaker.
“I had lost 10 times to Murray, and Jan wanted to show me in what patterns I had lost points, what I needed to avoid and how I should try to direct play, and it helped me enormously,” Simon said. “Doing a video is easy; all you have to do is film something and cut it into parts. But the hard part is to know how to use it intelligently. That’s what’s interesting, and that’s what the coach’s job should be. He should give only the essential to the player.”
Simon said statistics could be dangerous. “I’ll give you an example,” he said. “The data might tell us that if I go to net attacking a certain player’s backhand, I win 80 percent of the points. But if you play the match and go every time to the backhand, you are not going to win 80 percent of the points anymore because the player is going to know that it’s coming always to the same place.”
Coaches and tennis parents have been filming matches and practice sessions on a regular basis since the advent of the video camera. But one of the first tennis coaches at the elite level to make use of video to dissect opponents’ patterns was the Australian Darren Cahill when he was coaching Lleyton Hewitt and Andre Agassi in the early 2000s.Coaches and tennis parents have been filming matches and practice sessions on a regular basis since the advent of the video camera.

He received his inspiration from Australian rules football, which his father, John, played and coached at the professional level. Cahill said he bought a system called SportsCode from the Australian Football League.He received his inspiration from Australian rules football, which his father, John, played and coached at the professional level.

“The A.F.L. clubs got it from the N.F.L. and basketball in America, and I used it for a lot of the Lleyton Hewitt matches when I was with him and then took it on through with Andre,” Cahill said. “I think it’s under-tapped, value-added in tennis, and we don’t really go after it enough in coaching, and I think we’re finding more and more people are starting to invest in that.”“The A.F.L. clubs got it from the N.F.L. and basketball in America, and I used it for a lot of the Lleyton Hewitt matches when I was with him and then took it on through with Andre,” Cahill said. “I think it’s under-tapped, value-added in tennis, and we don’t really go after it enough in coaching, and I think we’re finding more and more people are starting to invest in that.”

Cahill said he did so “because I thought it was an edge, simple as that.”Cahill said he did so “because I thought it was an edge, simple as that.”
Maintaining that edge was labor intensive. Cahill said it could take him “six or seven hours” to go through footage of a three-hour match, isolating and analyzing the elements worth highlighting to Hewitt or Agassi.Maintaining that edge was labor intensive.

“It was a lot of man hours, but it was ultimately worth it,” he said. “Because you can sit a tennis player down and watch a three-hour match and it sort of gets lost in the wash, but if you can sit a player down and say there are three specific things I need you to look at, and it’s going to take a matter of 11 minutes and you can go to each of those specific things, I think the message goes home much quicker and harder.”
Cahill said Agassi liked the video package short and sweet. “Ten or 15 minutes of good stuff and that was it,” Cahill said. “But I used it a lot. For me to be able to deliver a message to him or find out where a guy is serving on a big point or to get a feel for what side he might cover at the net or to get a feel for Andre as well, if he’s giving up too much space on the forehand side when he’s going backhand to backhand, we could designate the video to find those areas.”Cahill said Agassi liked the video package short and sweet. “Ten or 15 minutes of good stuff and that was it,” Cahill said. “But I used it a lot.

Performance analysis systems have become more nimble and sophisticated, but long hours remain part of the job description. In Melbourne, at Tennis Australia’s new video performance analysis center, McMurtrie said he had only one day off in December and January: Christmas Day.Performance analysis systems have become more nimble and sophisticated, but long hours remain part of the job description.

“We’re the only ones to my knowledge who do coded matches to this degree,” McMurtrie said in an interview in Melbourne. “So you can say, ‘O.K., show me where Serena Williams serves on a break point,’ and we can give you the video of that over so many matches.”“We’re the only ones to my knowledge who do coded matches to this degree,” McMurtrie said in an interview in Melbourne. “So you can say, ‘O.K., show me where Serena Williams serves on a break point,’ and we can give you the video of that over so many matches.”
McMurtrie said a player like Stosur would then receive a link to the processed footage that she and her coach, David Taylor, could then access through a touch-screen tablet computer.McMurtrie said a player like Stosur would then receive a link to the processed footage that she and her coach, David Taylor, could then access through a touch-screen tablet computer.
“Dave probably chats to him more about all the stuff rather than me directly, but we certainly use it a lot, and he puts in a lot of work,” Stosur said of McMurtrie. “And it’s great to see tendencies or shot placement, serves, whatever it is, and I think if you can have that information for a player you’ve actually played, obviously it’s more relevant than information of them playing just anybody on tour. But I do certainly feel like it’s got a big place in trying to work out a game plan.”
What is unusual about Tennis Australia’s proprietary system is the depth of its database and its ability to analyze even obscure players well outside the top 100. They have also been filming junior players.What is unusual about Tennis Australia’s proprietary system is the depth of its database and its ability to analyze even obscure players well outside the top 100.

“We’re starting to record off all the streaming around the world,” McMurtrie said. “We do as much as we can ourselves, too, on court.” “We’re starting to record off all the streaming around the world,” McMurtrie said. “We do as much as we can ourselves, too, on court. Sometimes you’re out on some outer court and it’s 10:30 at night and you’re thinking, ‘What am I filming this for?’ And then the next week it comes in really handy.”
McEnroe said he was not “a huge believer” in exhaustive video analysis but said the U.S.T.A. now relied on the Dartfish system.McEnroe said he was not “a huge believer” in exhaustive video analysis but said the U.S.T.A. now relied on the Dartfish system.
“I think in tennis there is so much you already know about your opponent,” he said. “To me, it’s different than football or something where there are so many different options that can happen. In tennis, there’s not that much you can do.” “I think in tennis there is so much you already know about your opponent,” he said. “To me, it’s different than football or something where there are so many different options that can happen.

Magnus Norman, the Swedish former star now coaching Stanislas Wawrinka, said he had noticed a big change at the highest reaches of the professional game in only the past three years and that there were now free apps available that rivaled some of the expensive systems.Magnus Norman, the Swedish former star now coaching Stanislas Wawrinka, said he had noticed a big change at the highest reaches of the professional game in only the past three years and that there were now free apps available that rivaled some of the expensive systems.
“We use it more at our academy when we work on technique, looking at our own players’ strokes and stuff like that because it’s much easier to examine all that when it’s slow motion,” Norman said Saturday. “But I obviously know a lot more coaches, myself included, who are using it to see patterns and how opponents play when they are tight and how they play when they are leading.” “We use it more at our academy when we work on technique, looking at our own players’ strokes and stuff like that because it’s much easier to examine all that when it’s slow motion,” Norman said Saturday. “But I obviously know a lot more coaches, myself included, who are using it to see patterns and how opponents play when they are tight and how they play when they are leading. It’s getting absolutely more popular in tennis as in other sports.”

“The video really can be a plus, but you have to really use it right, otherwise it’s too much information, and it can be almost paralyzing,” he said. “The video really can be a plus, but you have to really use it right; otherwise it’s too much information, and it can be almost paralyzing,” he said. “Tennis is in the moment. It’s about instinct, too. When the ball comes, you’ve got to hit it and perhaps your video analysis determined it was better to return serve to a certain spot, but if at that moment you really feel you want to put it somewhere else, you still need to listen to that. And you need to do that.” quicker.
