Germany's Anna-Lena Groenefeld announces on her web site that she’ll become a doubles specialist in 2012. The 26-year-old was ranked as high as No. 14 in singles in 2006.
"The 2011 season was one that delivered mixed results for me personally, highlighted by reaching two WTA Tour doubles finals while at the same time struggling with my form in singles," she wrote. "I’ve come to the conclusion that it will be in my best interest to primarily focus on doubles for now. My time as a singles player on the WTA Tour has been blessed with wonderful moments of joy and triumph, but I am at a point in my career, where it is time to move on and do what I feel like is best for me."
