A spot in the next round is at stake on Tuesday, when Darwin Blanch goes up against Taylor Fritz in the US Open first round. Taylor Fritz has won 8 of the last 10. Darwin Blanch has won 2 of the last 10.

The serve is where this match separates: Fritz has been winning 74.6% of first-serve points to Blanch's 69.9%, and on hard that gap compounds fast. Blanch needs several things to break right at once; the percentages say they usually don't.
