Kevin Stadler stretches his lead in the Alstom Open de France (French Open) to four shots. Kevin Stadler / Getty Images Kevin could only put together a +1 over par 72 today, but his total of -9 under par was still way ahead of the field. Only three players in the entire field managed to break 70 today. Kevin had problems with a re-occurring back problem; "It's a little tight, it's been a little out of whack all week. Luckily didn't give me a whole lot of trouble the first couple of days, but it today it turned up a bit. I'm still able to swing so should be fine." "I got about what I deserved out of my game today. I didn't play that great, made a whole lot of pars and did not have nearly as many looks as I had the last couple days, but you can't expect to play that well for four days in a row." "I knew I really didn't have to do anything crazy today. A couple less would have been nice, but overall I'm happy the way it went." Tied in second place at -5 under par are Thongchai Jaidee and Frenchman Victor Riu, Victor returned a third round score of +2 over par, while Thongchai made up some ground with -2 under par 68. US Open Champion Martin Kaymer is six shots off the lead after an even par third round of 70. He still hopes to go low tomorrow and try to put some pressure on the leader; "I think since the first day he's running away a little bit, so I guess he likes the golf course as much as I do. So I think it will be difficult to catch him." "If the weather stays like this, I just need to shoot a very, very low score tomorrow. If you get within two or three shots of him, he might get some nerves the last three or four holes because it's a tough finish." "But the way he plays golf and the way I know him, he's a very laid-back guy so it will be difficult to catch him. I can only try to shoot as low as I can to be happy with myself." Defending Champion Graeme McDowell struggled, carding a +3 over par 73, and is now eight shots off the pace. He too is looking to go low tomorrow; "It was tough to find a rhythm, it was playing pretty difficult. It was nice to string a few birdies together and get myself back into it and as I made the turn I was feeling good about myself, my swing and my position in the tournament." "My swing off the 10th and 13th tee has been haunting me a bit, I'm just not committing to those shots and missing them all left. I'm disappointed with that back nine because I really felt like I swung the club decently today. "All I can do is try to shoot a 66 or 67 and there's a 75 or 76 waiting for anyone on this golf course."
