A spot in the next round is at stake on Tuesday, when Alex Michelsen goes up against Frances Tiafoe in the US Open quarterfinal. Frances Tiafoe has won 4 in a row and 9 of the last 10 overall. Alex Michelsen brings a 4-match winning streak into this one, 7-3 across the last ten.

The underlying stats are tight across the board — this is a matchup decided by a handful of points. A tiebreak or two would surprise nobody, with Tiafoe fractionally more likely to land the big points.
