I was court side yesterday, a few rows back. Kokky was the aggressor throughout the match, getting his forehand in play more often. Jack's forehand seemed to lack depth and penetration a lot of the time and sat up for Kokky's backhand quite nicely. Kokky just didn't have the mental game to close it out despite dominating 60/40 overall. Jack did incredibly well to break back in the 3rd, but I feel Kokky lost this match as opposed to Jack winning it.
