Anderson, Karlovic Take Newport Wild Cards

Sock is the third wild card

Kevin Anderson and Ivo Karlovic have accepted wild cards into the Hall of Fame Open in Newport, Rhode Island, joining fellow wild card Jack Sock in the ATP 250 field.

Anderson will compete at the grass-court tournament for just the second time, having also played there in 2008 when he was 22. The South African star has proven a dangerous foe on this surface. In 2018, he reached the Wimbledon final.
