I have Ljubicic today for a variety of reasons. Nieminen has just barely hung into this tournament and saved many match points while Ljubicic had a bye in the first round and then won in straights against Dent in the 2nd. I think Nieminen finally runs out of steam today against the strong service game of Ljubicic which should be enough. Ljubicic is deadly on first serve's and that leaves a tired Nieminen to struggle against him. Nieminen dropped serve 3 times in his opening round match and twice in the 2nd round. If he continues to do the same Ljubicic should be able to sustain and win around 6-4 6-4. I think the odds on him favor him considerably given the circumstances and how they got to this point. Ljubicic has played good tennis recently also falling in three sets not to long ago to Ferrer after a solid run and a win over Murray. I think this may be the play of the day right now.
