The first casualties among the seeds came quickly. Luca Van Assche beat Cameron Norrie 6-7(6), 6-2, 6-2, 6-3, taking the last three sets after losing a tight opener.
In the women's draw, Kamilla Rakhimova removed 27th seed Barbora Krejcikova 7-6(4), 6-2, the tiebreak effectively deciding a match the former Wimbledon champion never settled into.
Elsewhere the seeds held: Jessica Pegula and Daniil Medvedev both came through their openers without dropping a set.
