Tsitsipas roars our to a 5-love lead against Krajinovic before losing 6-3, 1-6, 3-6. Stefanos didn't play badly at all (34/16 w/ue ratio) but the match is a recent pattern starting with his downward turn in the French Open final and his wipeout to Tiafoe at Wimbledon. I think these extremes from match to match, sometimes from set to set, can be traced to grief. His much loved grandmother died five minutes before the start of the French Open final, and his performances since then look clouded by grief--stretches where you are okay and then stretches when you just can't focus on anything at all very well. You have to feel for him.
With his stylish, technically-sound game, Krajinovic always looks like a top ten player--that is, until you watch him against top ten players and then his insufficiencies finally emerge. Today he kept his fragile nerves intact through the end, having a field day on his backhand where he hit no less than 26 winners.
