Wimbledon 2012: Serena Williams raises security fears with 'I was mobbed' claim Asked whether Wimbledon officials ought to address security concerns in their match scheduling, she replied: "Yeah, I think they should take that into account. I was almost knocked over. There were tons of security guards just going nuts and screaming. I've never heard them scream so loud. In a lighter mood Williams acknowledged she was quite capable of holding her own in a mêlée. "I wasn't scared," the sixth seed said, smiling. Nobody is going to knock me over for real. I'd like to see that happen - you guys know how I can get. Maybe that's why I got to go on Court No 2, because they knew I could back myself up. When it boils down, I guess I didn't really need it. The 30 year-old's aversion to Court No 2, because of the lesser exposure and limited security, has a degree of validity. Wimbledon guidelines stipulate that a player's court allocation is typically dictated by the size of his or her fan base and Williams, as a 13-time grand slam champion, can boast one of the largest. The order of play rules for this year's tournament state: "The major marquee players will normally be scheduled on the stadium courts. This is expected by both the paying public and TV audiences alike. Players with a large fan following will usually, by necessity, be scheduled on courts offering the greatest security. Mercifully for Williams, the remoteness of her outpost did not diminish the quality of her performance. Shvedova was an awkward opponent, having secured an extraordinary "golden set" - winning 24 straight points - in her third-round victory over Sara Errani, but Williams overcame the Kazakh's resistance with potent groundstrokes and her ever-reliable serve. She suffered a scare when losing the second set surprisingly tamely, but her victory was still impressive in the drizzle and capricious wind. Williams had looked in a hurry to beat the weather with her rapid opening set. Indeed, her winning shot, a backhand to which Shvedova could not come close, was unleashed with all the other courts already taking shelter from the rain. "We both wanted to keep playing as it was so deep into the match," she explained. Buffeted by a strong breeze, she carved out her solitary match point with a wonderful backhand lob at 6-5, 30-30, in the deciding set and pounced on the opportunity. The relief, as she performed her regal wave to the galleries, was palpable. The only problem, sadly, came when she departed to face her public.
