Ivo Karlović (Croatian pronunciation: [ǐːʋo kâːrloʋitɕ]; born 28 February 1979) is a Croatian former professional tennis player. His height of 211 cm (6 ft 11 in) makes him the joint-tallest ranked tennis player in history (along with Reilly Opelka). He won eight ATP Tour singles titles between 2007 and 2016. He was a serve-and-volleyer and officially held the record for the fastest serve recorded in professional tennis, measured at 251 km/h (156 mph), before being officially surpassed by John Isner in 2016. He was considered one of the best servers on tour, and held the record for career aces from 1991 onwards with 13,728 (not including Davis Cup) before the record was broken by Isner on July 1 2022. This makes him one of only five players since 1991 to surpass 10,000 aces. His height enabled him to serve with high speed and unique trajectory.
