Second seed Stephane Houdet took three sets to get past Belgian Joachim Gerard in the opening round of the Australian Open men’s wheelchair singles on Wednesday.
The 25-year-old world number four claimed the first set 6-4, before last year’s French and US Open champion worked back into the contest to win the final two sets.
Gerard managed only one break in the final two sets, as Houdet moved into the semifinals with a 4-6 6-2 6-2 win.
Houdet will play Argentina’s Gustavo Fernandez in the final four after the world number five defeated Houdet’s French compatriot Michael Jeremiasz 6-4 6-1 on Court 5.
Australian Adam Kellerman failed to advance past the first round for the second successive year, losing in two tight sets against Dutch world number six Maikel Scheffers.
Kellerman reached the main draw after defeating compatriot Ben Weekes in a wildcard playoff on Monday, but pushed the 31-year-old former world number one, eventually falling 7-5 7-5.
First seed Shingo Kunieda commenced his title defence with a comfortable 7-5 6-2 win over Great Britain’s Gordon Reid.
The first round of women’s wheelchair singles saw no surprises as top seed Sabine Ellerbrock toppled South African Kgothatso Montjane in 60 minutes.
After reaching her maiden grand slam final at last year’s Australian Open, the world number two produced a dominant serving display to win 6-1 6-3.
In the second round the German will play Jordanne Whiley, after the 21-year-old Briton defeated Sharon Walraven 6-3 6-3.
Whiley is looking to build on an impressive 2013 which included a first career ITF title.
Jiske Griffioen defeated Lucy Shuker 6-1 6-2, booking a semifinal spot against Japanese second seed Yui Kamiji, who beat Marjolein Buis 6-1 6-4.
Meanwhile, Australian Dylan Alcott was unable to overcome first seed David Wagner in the opening round of the quad wheelchair singles’ round-robin on Court 7.
The former Paralympic basketball player shocked world number one Wagner to win the opening set 6-4, but was unable to convert a match point in the second set.
The American prevailed 4-6 7-6(5) 6-3 in just under three hours, but Alcott continued his promising start to the season after recently returning to the sport.
