SAN FRANCISCO (AP) — Barry Bonds wants another turn at bat in the federal case against him in San Francisco.

The slugger’s attorneys filed a motion Wednesday asking a judge to change Bonds’ obstruction of justice conviction to an acquittal or schedule a new trial.

He was convicted of obstructing a grand jury’s steroids investigation by giving an evasive answer during questioning in 2003. The trial ended in April with a mistrial on three perjury counts and a conviction on the single obstruction count.

Bonds’ lawyers argue he was unfairly convicted of “unauthorized rambling” in discussing being a celebrity child when asked whether his trainer ever injected him with a syringe. The lawyers insist that Bonds answered the question directly during further questioning.

A July 1 hearing is scheduled to consider the latest motion.
