Some context: Callen Radcliffe "Cal" Tjader, Jr. ( CHAY-d@r; July 16, 1925 - May 5, 1982) was an American Latin jazz musician, known as the most successful non-Latino Latin musician. He explored other jazz idioms, even as he continued to perform the music of Cuba, the Caribbean, and Latin America for the rest of his life. Tjader played the vibraphone primarily. He was accomplished on the drums, bongos, congas, timpani, and the piano.
Tjader soon quit Shearing after a gig at the San Francisco jazz club the Blackhawk. In April 1954, he formed the Cal Tjader Modern Mambo Quintet. The members were brothers Manuel and Carlos Duran on piano and bass respectively, Bayardo "Benny" Velarde on timbales, bongos, and congas, and Edgard Rosales on congas (Luis Miranda replaced Rosales after the first year). Back in San Francisco and recording for Fantasy Records, the group produced several albums in rapid succession, including Mambo with Tjader.  The Mambo craze reached its pitch in the late 1950s, a boon to Tjader's career. Unlike the exotica of Martin Denny and Les Baxter, music billed as "impressions of" Oceania (and other locales), Tjader's bands featured seasoned Cuban players and top-notch jazz talent conversant in both idioms. He cut several notable straight-ahead jazz albums for Fantasy using various group names, most notably the Cal Tjader Quartet (composed of bassist Gene Wright, drummer Al Torre, and pianist Vince Guaraldi). Tjader is sometimes lumped in as part of the West Coast (or "cool") jazz sound, although his rhythms and tempos (both Latin and bebop) had little in common with the work of Los Angeles jazzmen Gerry Mulligan, Chet Baker, or Art Pepper.  Tjader and his band opened the second Monterey Jazz Festival in 1959 with an acclaimed "preview" concert. The first festival had suffered financially. Tjader is credited with bringing in big ticket sales for the second and saving the landmark festival before it had even really started. The Modern Mambo Quintet disbanded within a couple of years. Tjader formed several more small-combo bands, playing regularly at such San Francisco jazz clubs as the Blackhawk.

Some context: Kim Antonie Lode Clijsters (Dutch pronunciation: [kIm 'kleist@rs] ( listen); born 8 June 1983) is a Belgian former professional tennis player. Clijsters is a former world No. 1 in both singles and doubles. Clijsters won 41 singles and eleven doubles titles. She won four Grand Slam singles titles: three at the US Open, in 2005, 2009, and 2010 and one at the Australian Open in 2011.
Clijsters had won the Belgian Junior Championship by the age of 11 and joined an academy in Antwerp two years later. It was there she met Carl Maes, her coach for the first and last stages of her professional career. Clijsters was an accomplished junior player. In singles, she finished as runner-up in the 1998 Wimbledon junior event, finishing 11th in the year-end singles ranking. In the same year in doubles, Clijsters won the French Open title with Jelena Dokic, defeating Elena Dementieva and Nadia Petrova in the final, as well as the US Open with Eva Dyrberg, defeating former partner Dokic in the final. Clijsters ended the season as no. 4 in the International Tennis Federation junior doubles world ranking.  In 1999, Clijsters made her breakthrough professionally. At her first WTA tournament in Antwerp, she qualified and lost to the eventual finalist Sarah Pitkowski-Malcor in the quarterfinal, after failing to convert a match point. She also reached the doubles quarterfinals of the same event with India's Nirupama Vaidyanathan, defeating Vanessa Menga and Miho Saeki 7-5, 6-4.  Playing through the qualifying rounds at Roehampton, she made it to the main draw of Wimbledon. Clijsters won six matches in a row, while only losing 25 games. She defeated no. 10 Amanda Coetzer en route to the fourth round, during which Clijsters lost to her childhood idol, Steffi Graf, in straight sets, in difficult rainy circumstances. Later that summer, Clijsters reached the third round of the US Open, losing to eventual champion Serena Williams after serving for the match. In the autumn, Clijsters won her first Women's Tennis Association (WTA) singles title in Luxembourg. She followed up with her first WTA doubles title in Bratislava, partnering Laurence Courtois.
