• Raonic cruised, needing only 17 minutes to take the first set, but the 37-year-old Haas battled back to take the final two sets to tiebreaks. The seventh-seeded Canadian also hit a 145-mph serve to claim the third-fastest serve in Wimbledon history. ...
• Reigning U.S. Open champ Cilic clinched his three-and-a-half-hour, five-set marathon after 80th-ranked Berankis double-faulted.
• Goffin will advance to face 2006 Aussie Open finalist Marcos Baghdatis, who rallied from down two sets to beat John Millman.
• A ball boy collapsed during the Isner-Ebden match and was carried off the court on a stretcher. Wimbledon organizers tweeted later that the boy "has been treated and is feeling much better."
• The always vocal Kyrgios was at it again Wednesday, unleashing his anger at the chair umpire.

Fernando Verdasco defeats No. 32 Dominic Thiem 5-7, 4-6, 5-7, 6-3, 6-4
