Sam Querrey upset Novak Djokovic in the third round of Wimbledon last week (7–6(8–6), 6–1, 3–6, 7–6(7–5)). Querrey was ranked 28th in the World while Djokovic's ranking was 1st. Djokovic had also won his previous thirty grand slam matches.
From a body language perspective, note the configuration of the two men's torsos at the end of the match. Querrey, the victor, leans into the "handshake", whereas Djokovic's torso is leaning slightly backward. Sam Querrey even leans over the while Djokovic's hand only comes up to the plane of the net. And although Djokovic is certainly an alpha male, in this moment Querrey is, understandably, displaying an even greater alpha status (thus Djokovic, in this context, is the Beta). The loser will rarely lean in during an after-match congratulation.
