Bob, Mike Bryan Through To QFs At Delray Beach

Klaasen, Venus move into last four in Marseille 
Bob Bryan and Mike Bryan, top seeds at Delray Beach Open, advanced past #NextGenATP stars Taylor Fritz and Stefan Kozlov, 7-5, 6-0 on Wednesday.

The four-time champions needed one hour, two minutes to book their place in the quarter-finals, where they'll face fellow Americans Jack Sock and Jackson Withrow.

In other action, top seeds Raven Klaasen and Michael Venus reached the Open 13 Provence semi-finals after a 6-3, 6-3 win over Florin Mergea and Daniel Nestor. Klaasen and Venus reached their second semi-final of the season (Auckland) with great composure, saving all six break points they faced in the 57-minute contest.

Rohan Bopanna and Edouard Roger-Vasselin needed a Match tie-break to join Klaasen and Venus in the final four. The Indian-French duo dropped just five points behind its first serve, but needed to come from a set down to beat Jamie Cerretani and Adil Shamasdin 3-6, 7-6(3), 10-4. Marcus Daniell and Dominic Inglot edged two tie-break sets to overcome Maximilian Marterer and Joao Sousa 7-6(11), 7-6(2). The fourth seeds saved five set points in a dramatic first set before eventually booking a second-round clash with Jonathan Eysseric and Gilles Simon.

David Marrero and Fernando Verdasco upset fourth-seeded team Santiago Gonzalez and Julio Peralta, 7-5, 3-6, 10-2 to advance to the semi-finals at the Rio Open presented by Claro. The Spanish pair will play the winners between second seeds Jamie Murray/Bruno Soares and Roman Jebavy/Leonardo Mayer for a place in the final.
