Melbourne, 26 January 2012 | tennis.com.au

It was a tough day at the office for Australians Dani di Toro and Ben Weekes who are competing in the Australian Open wheelchair championships.

Di Toro, a former world No.1, faced Marjolein Buis of the Netherlands. Di Toro fought hard, but Buis came out on top in a tight second set tiebreak, winning 6-2 7-6(3).

In the men’s wheelchair singles, Ben Weekes took on Swede Stefan Olsson. Olsson proved to be too good on the day, winning 6-1 6-0 to move through to the semifinals.

Di Toro is still in the running in the doubles event with partner Annick Sevenans of Belgium. They will play second-seeded pair Aniek Van Koot and Buis.

The two will have to patch up any differences though, as they will be competing together in the doubles event. They are scheduled to take on the second seeds, Dutch duo Ronald Vink and Roben Ammerlaan.

The men’s and women’s singles and doubles semifinals will be played today at Melbourne Park.
