Marta Kostyuk and Storm Hunter meet in the first round at US Open on Sunday. Marta Kostyuk is 7-3 across recent matches. Storm Hunter comes in at 6 wins from the last ten.

Kostyuk's 63.5% behind the first serve (against 59.4% for Hunter) means break chances should be scarce in one direction. The edge belongs to Kostyuk — real, but not the kind you take for granted at this level.
