Djokovic continues its march to complete the calendar year Grand slam, which means winning all four majors (Australian Open, French Open, Wimbledon and U.S. Open) in the same year. After winning the first three tournaments, he's now qualified for the semi-finals at the US Open.
In the quarter finals, he lost the first set to Matteo Berrettini, but then quickly turned it around and won three straight sets 'easily' and final score was 5-7, 6-2, 6-2, 6-3. I only saw the highlights, but that was great tennis from him, if he can keep that level, I don't see anybody able to stop him. However, the semi finals will be against Alexander Zverev, who beat him at the Tokyo Olympics. Probably an interesting match to check tomorrow.
