The thing about line movement in tennis is that it really doesn't mean anything if you look at the overall picture. Linesmakers have been exagerrating the lines on the perceived marquee players-seeds all season more than I can remember in the past. A lot of this so called movement is market correction for idiotic lines. Nishikori for example at over -300 when he barely scraped by in the opening round while Soeda has beaten some legit players on hard courts. Never should have been that wide a margin for a guy who has played four matches in four months and not looked overly convincing in his wins.

Line movement this morning, Mayer was backed with a 20 to 25 cent swing. He got raped by Haas. Mathieu drifted out to -150 and then was down to -125 prematch. He rolled over Gulbis after the first set.

If you made all your plays based on line movement, I don't think you would fare much better over the long run than you do simply sticking to your own picks.
