The former tennis superstar has written a book about his time in prison in the UK. Boris Becker uses "Inside" to write about his time behind bars, portraying himself as both a fighter and a victim. "My 1985 Wimbledon victory is partly to blame for this," he tells fans and journalists at the book launch. These initially concern his rivalry with Andre Agassi, who challenged Becker's status as the crowd favorite at Wimbledon in the early 1990s. The proceedings ultimately led to Becker's prison sentence.
