Three-time Grand Slam winner Lindsay Davenport announced that she is pregnant and has taken herself off the WTA Tour indefinitely.
After agreeing to participate in the Australian Open last week, the 32-year-old former world No. 1 pulled out of the event on Thursday.
"Of course this unexpected, but exciting, surprise now means I will be putting tennis on hold for the foreseeable future," Davenport said.
After returning to the tour after the birth of her first child, Jagger, Davenport won four of her 55 career singles titles.
Davenport has won three Grand Slam titles - US Open in 1998, Wimbledon in 1999 and the Australian Open in 2000.
She has 37 doubles titles to her credit, including triumphs at Roland Garros in 1996 (with Mary Joe Fernandez), the US Open in 1997 (with Jana Novotna) and Wimbledon in 1999 (with Corina Morariu).
