British number one Cameron Norrie beat Brandon Nakashima to claim his first grass-court win of the year and reach the Eastbourne quarter-finals.
He could face either compatriot Dan Evans or Maxime Cressy next.
There are a number of Britons in action on Wednesday, while American great Serena Williams will take to the court in the women's doubles once again.
Williams, a 23-time Grand Slam singles champion, and partner Ons Jabeur will play Shuko Aoyama and Chan Hao-ching from 16:50 BST.
Katie Boulter will face two-time Grand Slam champion Petra Kvitova as she seeks to back up her second-round win over last year's Wimbledon finalist Karolina Pliskova.
