Sho Shimabukuro vs Hubert Hurkacz — R128 — Cincinnati Open

Nothing came off the Hurkacz return games for free. The 29th-ranked Pole held all eight of his service games behind 13 aces and 82 percent of first-serve points won, breaking three times from five chances, while Shimabukuro, into the draw as a lucky loser, went 0-for-2 on his own break points and dropped serve in the opening game of the match. Hurkacz needed a second match point after the first was saved, and the win nudges a hard-court season that had gone 3-7 coming in.
