Federal prosecutors urged an appellate court to deny Barry Bonds' request for a rehearing of his attempt to overturn his obstruction of justice conviction.

The career home runs leader was convicted in April 2011 stemming from his 2003 testimony before a grand jury investigating BALCO. That conviction was upheld in September in a unanimous decision by a three-judge panel of the 9th U.S. Circuit Court of Appeals in San Francisco. The 27 active judges on the appellate court will hold a vote, and a majority is required to grant the rehearing.

Despite the attempt to overturn the conviction, the former Giants superstar already has agreed to start the sentence imposed by U.S. District Judge Susan Illston: 30 days of house arrest with location monitoring, two years' probation, $4,100 in penalties and 250 hours of community service.

  • Manager Don Mattingly agreed to a new three-year deal with the Los Angeles Dodgers that takes him through the 2016 season. Financial terms weren't disclosed. "Knowing the organization has confidence in you is important to me as a manager," Mattingly said. The Dodgers reached the N.L. championship series in 2013, automatically triggering an extension of Mattingly's contract that was set to expire at the end of last season. General manager Ned Colletti said the new deal is "well-deserved."

  • The Dodgers are in contact with Casey Close, the agent for pitcher Masahiro Tanaka. "They're in the feeling-out process," Colletti said. Tanaka is expected to a sign a contract worth more than $100 million. In addition to that, the team that lands him will owe $20 million to Tanaka's Japanese team, the Rakuten Golden Eagles.
