San Francisco Giants spokeswoman Staci Slaughter said Tuesday night that the reigning World Series champions in the process of replacing the plaque, which hung on the brick facade inside the ballpark beneath the flag court area in right-centre field until a few days ago. The team is investigating where the missing hardware might be, Slaughter said.

Bonds, the seven-time NL MVP, broke Hank Aaron's home run record on Aug. 7, 2007, at home in San Francisco. The slugger hasn't played since that season, finishing his 22-year major league career with 762 total home runs. He has been back to the ballpark as a fan in recent seasons, receiving standing ovations from the crowd that still cheers him despite allegations he used performance-enhancing drugs to fuel his pursuit of Aaron's mark.
Bonds has long denied ever knowingly using steroids or performance-enhancing drugs and the 48-year-old slugger appealed his obstruction of justice conviction from April 2011 on one count of giving an evasive answer to a 2003 grand jury investigating illegal steroids distribution. In February, a lawyer for Bonds urged a federal appeals court to toss out the slugger's obstruction of justice conviction, saying a rambling answer he gave while testifying before a grand jury in December 2003 was not a crime.
