Tennis star Lindsay Davenport can now add mom to her list of impressive titles.

On Sunday, Davenport and her husband, Jonathan Leach, welcomed their first child, a son named Jagger Jonathan Leach, her rep confirms.

The baby, who weighed in at 8 lbs., 1 oz., was born at 6:15 p.m. in Newport Beach, Calif.

“Lindsay and Jon are ecstatic and Jagger is healthy and doing great,” Davenport’s agent, Tony Godsick, told PEOPLE Tuesday.

Davenport, 31, and Leach, got married in 2003. They announced they were expecting in December of last year. The pregnancy prevented Davenport from competing this season.

Davenport has won 51 titles in singles and 36 in doubles, and was ranked No. 1 after the 1998, 2001, 2004 and 2005 seasons. She also took the U.S. Open singles title in 1998, Wimbledon in 1999 and the Australian Open in 2000, in addition to an Olympic gold medal in 1996.
