MELBOURNE (Reuters) - Former world number seven and Australian Open finalist Danielle Collins announced she would be retiring this season after a close second-round loss to world number one Iga Swiatek at Melbourne Park on Thursday.
The 30-year-old American, who had a 4-1 lead in the deciding set but went down 6-4 3-6 6-4 to the four-times Grand Slam champion, said she was sick of the travel and wanted to have a family.
