I didn't think he normally coached her, but he's probably standing in as he's keeping his evil eye on our girls.
Well, he was about in Sonay's box at Wimbledon, I believe sitting between her two normal ( one maybe past? ) coaches - so no need for a stand-in then. Then standing up once she'd won and gladhanding a number of folk who leaned over to congratulate him and ignored the coaches ( who admittedly weren't making themselves so conspicuous ). I had the sickbag out.
