Wickmayer got a key break at 5-5 in the first set and the second set's only break at 3-3 in her 75 64 triumph. The Belgian is still getting back in the swing of things after a back injury forced her out of action after the US Open last year until her second round showing last week in Auckland.
"It's an injury that's going to have my attention the rest of my career," Wickmayer said. "It needs a lot of exercise and a lot of rehab. I'm improving every day. I has been only two weeks that I've been playing points after five months out. It's the first time I've been injured badly and the first time I've had to come back. It's a different feeling, but I'm feeling healthy and happy."
"I got tired at the end," said Dellacqua, who had to hang on after her 75 43 lead evaporated. "I had lots of chances in the second set and early in the third to close it out. I'm excited to have my first win of the Australian summer, and hopefully a few more leading into the Australian Open."
Although this was her first WTA main draw match victory since Birmingham last June, Dellacqua finished 2011 by winning 30 straight matches en route to capturing six consecutive ITF Women's Circuit events. "My first goal is to get back inside the Top 100," she said. "I definitely feel like I'm in the position now to be able to compete with these girls week in and week out."
No.5 seed Jarmila Gajdosova continued her good fortune in Hobart by beating Ayumi Morita, 63 64. The Australian did not lose a set en route to the title here last year. No.4 seed Angelique Kerber, a semifinalist last week in Auckland, continued her strong start to the season with a 62 64 defeat of Elena Vesnina.
In the thriller of the day, Tsvetana Pironkova outlasted qualifier Heather Watson in almost three hours, 76(10) 36 76(2). In the first set tie-break, Watson had one set point and Pironkova six. Pironkova rallied from a 5-2 deficit in the third set, withstanding two match points at 5-3.
