A spot in the next round is at stake on Saturday, when Alejandro Tabilo goes up against Ben Shelton in the Washington quarterfinal. Ben Shelton comes in at 7 wins from the last ten. Alejandro Tabilo is 4-6 across recent matches.
Shelton's 74.5% behind the first serve (against 71.1% for Tabilo) means break chances should be scarce in one direction. Expect resistance, but the match-level math tilts clearly toward Shelton.
