Alex Michelsen and Taylor Fritz meet in the quarterfinal at Washington on Friday. Taylor Fritz has won 8 of the last 10. Alex Michelsen has won 6 in a row and 9 of the last 10 overall.
The serve is where this match separates: Fritz has been winning 74.6% of first-serve points to Michelsen's 69.7%, and on hard that gap compounds fast. A tiebreak or two would surprise nobody, with Fritz fractionally more likely to land the big points.
