French Open 4th Round, Monday

Here are my predictions for Monday's matches.

Roger FEDERER v Tommy HAAS Federer to win 3-0 @ 1.59
Federer has the ability to beat Haas, who may have previously caused him problems but is unlikely to today.
Juan Martin DEL POTRO v Jo-Wilfried TSONGA Del Potro to win 3-0 @ 3.75
Del Potro should knock Tsonga out this competition, the Frenchman doesn't have the experience on these courts to beat Del Potro.
Tommy ROBREDO v Philipp KOHLSCHREIBER Robredo to win 3-0 @ 5.7
Robredo is underestimated here and could be in for a big tournament. Too much emphasis on Kohlschreiber's elimination of Djokovic and not enough on the matches of Robredo in these odds.
Andy RODDICK v Gael MONFILS Monfils to win 3-0 @ 5.0
Roddick is dangerous but I suspect that Monfils will knock him around the court far too much for him to win this.
