Sam Querrey takes his sporting allegiances pretty seriously, even when in the midst of his best run at a grand slam. Golden State Warriors star and NBA Defensive Player of the Year Draymond Green stopped by Wimbledon on Wednesday and took some time to chat to Querrey on the same day he stunningly knocked out defending champion Andy Murray in the quarter-finals. Querrey, though, has high hopes for Lakers rookie Lonzo Ball, who has posted two triple-doubles in Summer League.
