Nathaniel Lammons and Jackson Withrow continued their Winston-Salem Open run on Thursday when they booked their ticket to the semi-finals.

After ousting top seeds Rajeev Ram and Joe Salisbury in the opening round, the Americans cruised past Simone Bolelli and Mate Pavic 6-3, 6-2 in just 64 minutes. Lammons and Withrow, who are aiming for their third tour-level title of the season (Newport, Atlanta), will next clash against third seeds Hugo Nys and Jan Zielinski.

Second seeds Lloyd Glasspool and Neal Skupski also advanced to the last four Thursday after they saved a match point to down Australians Matthew Ebden and John-Patrick Smith 7-5, 4-6, 11-9. The British duo won three straight points from 8-9 in the Match Tie-break to set a meeting against Marcelo Demoliner and Matwe Middelkoop or Romain Arneodo and Ariel Behar.
