Australian Open - Fourth Round

Jeremy Chardy played five sets of the best tennis I've ever seen from him to take out former US Open champion Juan Martin del Potro. Chardy came out swinging from the first ball and often took the initiative in the match. When it looked like his challenge might come to an end, he produced some outstanding tennis to save break points in the 5th set and took his opportunity when it came not long after.

However, with all of that being said, Chardy wouldn't have been a favourite against Andreas Seppi before the draw was made, so we need not overreact off the back of a big win. At 10/11 Seppi is overpriced and can drag Chardy back down to earth. Both needed five sets in the third round, so neither has an advantage in that sense. I wouldn't be shocked if this went five sets, too.

After a long injury lay-off Svetlana Kuznetsova is on the verge of reaching the second week of a Grand Slam if she can successfully see off the challenge of Caroline Wozniacki. The match-up suits 'Sveta' well for the most part, as Wozniacki will allow her to dictate proceedings. Wozniacki's form has picked up since she allowed Sabine Lisicki to implode against her from a winning position.

Despite that upturn in form, Wozniacki was pushed around by Lesia Tsurenko too many times to ignore what Kuznetsova could do to her. The price is very appealing and has the makings of in-play trading material. I would be very surprised if Kuznetsova isn't odds-on at some point of this match. The big question is whether she will see it out to completion. They have met twice at the US Open in matches Kuznetsova should have won, but ultimately didn't. Expect another topsy-turvy affair when they meet in the fourth round.
