A spot in the next round is at stake on Tuesday, when Daniel Merida Aguilar goes up against Taylor Fritz in the Cincinnati round of 32. Taylor Fritz comes in at 8 wins from the last ten. Daniel Merida Aguilar 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 Aguilar's 64.3%, and on hard that gap compounds fast. The edge belongs to Fritz — real, but not the kind you take for granted at this level.
