Serena gets game penalty for calling umpire 'thief'
Serena Williams' bid for a 24th Grand Slam title imploded in a furious tirade against umpire Carlos Ramos, calling him a thief after he docked her a point for two code violations.
Her outburst then earned her a game penalty, prompting a further outburst to tournament officials and putting Naomi Osaka within one game of victory.
