His father was a Hungarian immigrant upholsterer. In his youth he had tennis lessons at the Berkeley Tennis Club. Kovacs had a reputation as an eccentric tennis player and showman on the court. Once, serving for a match point, he tossed three balls in the air - hitting the middle one for an ace. He was known to jump into the stands to applaud his opponents, and once staged a sit-down strike during a match. Kovacs won the singles title at the U.S. National Indoor Tennis Championships in March 1941, which was held at the Oklahoma Coliseum, after a straight-sets win in the final against Wayne Sabin. Kovacs was the No. 3-ranked American amateur in 1940 and the No. 2 in 1941. He was ranked the World No. 3 pro for 1941 by Ray Bowers. His best amateur result was a runner-up finish in the U.S. Amateur National Singles Championship in 1941, beating Jack Kramer and Don McNeill before losing to Bobby Riggs in a four-sets final. The 1942 professional tour consisted of round-robin matches between Don Budge, Bobby Riggs, Fred Perry, and Kovacs. The seasoned Budge ended up with the best record while Kovacs had the second best. From 1943 to the end of WWII, Kovacs served in the army. In the 1947 pro circuit, Kovacs scored 10 matches against Bobby Riggs', while losing 11 matches to Riggs, the 1947 Pro Champion. In the pro circuit, Kovacs' greatest result was winning the World Pro Championships held at Lakewood just outside Cleveland where he defeated Pancho Segura in the final in five sets. A week later he withdrew from the U.S. Pro Tennis Championships won by Segura. The previous year, in 1950, he had reached the final of that tournament, losing to Segura. Kovacs also reached the semifinals of the US Pro a further 4 times. Though the tennis activity was very limited between 1943 and 1945 Kovacs dominated all the players he met as Welby Van Horn, Don McNeill, Adrian Quist, Bill Tilden, Jack Crawford, Jack Jossi, Martin Buxby, Joe Whalen, George Lott, George Lyttleton Rogers. Kovacs was also responsible for something of a scandal over money in tennis, which before the Open era was strictly divided into amateurs and professionals. After he was barred from amateur tennis in 1941, he talked about how money was quietly - and widely - paid to supposedly amateur players for entering tournaments. After being evicted from the amateur ranks, he and Riggs turned professional at the same time, both signing a professional contract for $25,000. From December 1941 through April 1942 the Pro tour consisted of round-robin matches between Don Budge, Bobby Riggs, Fred Perry, and Kovacs. Budge ended up with the best record, 52 wins to 18 losses, ahead of Riggs 36-36 and Kovacs, 25 wins to 26 losses : Kovacs even led the very first part of the tour mainly because he had defeated Budge in their first five matches. After the tour he entered the U.S. Pro Championships and reached the semifinals and, as with the other great pros of the time, he then joined the U.S. Army. He was still a force in professional tennis into the 1950s; he played Pancho Gonzales in a match at the California Tennis Club in San Francisco in 1955 and nearly beat him. He spent his later years teaching tennis at the Davie Tennis Stadium in Piedmont, in Florida and at public courts near his home in Oakland.
Playing style
Although he showed flashes of brilliance his career results were relatively disappointing. It was said of him that on the right days, when he was briefly "in the zone", he could be unbeatable: Fred Hawthorne, reporter for New York Herald-Tribune who watched nearly all the early matches of the 1941-1942 pro tour thought that Kovacs at his best reached "sheer brilliancy never before excelled", but at other times Frank played "surprisingly poor tennis." For instance in his first pro match, on December 26, 1941 he defeated Don Budge and as late in his career as 1952, at 33, he was still able to defeat Pancho Gonzales then the best pro in the world. As tennis great Jack Kramer, and Kovacs' near contemporary, has written: "Kovacs had picture strokes, maybe the best Backhand, but he could never win anything because he didn't have any idea how to go about winning. He never had a set plan for a match. Hell, he never had a set plan for a shot. He could sort of decide what to do with it halfway through the stroke." Kovacs' best shot, says Kramer, was "a hard, angled backhand crosscourt, but he could never figure out how to set it up so he could take advantage of it." As Riggs said to Kramer one day: "...don't worry about Frankie.... He looks great, but give him long enough and he'll find some way to keep you in the match, and give him a little longer and he'll find a way to beat himself." Nevertheless, Kovacs had a very positive win-loss record against Kramer both in the amateur circuit and in the pro circuit too.
Personal life
Kovacs was married to San Francisco vocal coach Judy Davis in 1950 and they lived for many years in their home on in the Rockridge district of Oakland, until his death in 1990. His first marriage, on July 14, 1941, was to Virginia Wolfenden, also a tennis professional; they had a son, Frank Jr. His cousin was the entertainer Ernie Kovacs.
