A spot in the next round is at stake on Tuesday, when Alexander Zverev goes up against Luciano Darderi in the US Open round of 16. Alexander Zverev is 7-3 across recent matches. Luciano Darderi has won 3 in a row and 6 of the last 10 overall.

The serve is where this match separates: Zverev has been winning 73.7% of first-serve points to Darderi's 69.8%, and on hard that gap compounds fast. Darderi needs several things to break right at once; the percentages say they usually don't.

Alex Michelsen and Frances Tiafoe meet in the quarterfinal at US Open on Tuesday. Frances Tiafoe is rolling — 4 straight wins, 9 of 10 in recent play. Alex Michelsen is rolling — 4 straight wins, 7 of 10 in recent play.

Neither the serve numbers nor the ratings separate these two by much, which is why our number stays close to even. This one is close to a coin flip, and the lean toward Tiafoe is exactly that — a lean.
