A spot in the next round is at stake on Sunday, when Alex Michelsen goes up against Taylor Fritz in the Cincinnati round of 64. Taylor Fritz comes in at 8 wins from the last ten. Alex Michelsen has won 8 of the last 10.
The serve is where this match separates: Fritz has been winning 74.6% of first-serve points to Michelsen's 70%, and on hard that gap compounds fast. A tiebreak or two would surprise nobody, with Fritz fractionally more likely to land the big points.
