Barry Bonds' wife filed for legal separation in a Los Angeles court on Monday, the San Francisco Chronicle reported.
Bonds and the former Liz Watson married in 1998. They have a 10-year-old daughter, Aisha. Liz Bonds cited irreconcilable differences in papers submitted by her lawyer in Los Angeles Superior Court. She is seeking spousal support and joint legal and physical custody.
Bonds, Major League Baseball's career home run leader with 762, is awaiting trial in federal court on perjury charges. He is accused of lying under oath to a grand jury investigating the Bay Area Laboratory Co-operative when he said that he had never knowingly taken performance-enhancing drugs.
Bonds' first marriage, to Susann (Sun) Margreth Branco, ended in divorce in 1994.
The former Giants slugger has not played since the 2007 season, during which he passed Hank Aaron's career home run record of 755.
