NEWPORT, Rhode Island (AP) Sam Groth saved a match point before beating American qualifier Austin Krajicek 6-7 (3), 7-6 (2), 6-3 on Tuesday and setting up what should be a big-serving duel against top-seeded John Isner, a two-time champion at the Hall of Fame tournament.

Konstantin Kravchuk and Frank Dancevic each upset a seeded opponent in the first round of the grass court competition. Kravchuk beat No. 5 Victor Estrella Burgos 6-4, 6-4 and Dancevic eliminated No. 7 Tennys Sandgren 6-7 (5), 6-3, 6-2.
Akira Santillan, a 20-year-old Australian, closed out his first ATP main-draw match win with an ace in a 6-1, 6-2 result against Michael Mmoh.
