David Marrero

David Marrero Santana (born 8 April 1980) is a Spanish professional tennis player. Marrero won 14 doubles titles and reached a career-high doubles ranking of world No. 5 in November 2013.

2000–2007
Marrero earned his first world ranking late in 2000 as a 20-year-old, but he spent only a few weeks inside the top-500 until early 2005. By late 2005, he had made it into the top-300, but faded over the next year to close out 2006 outside the top-400. In the middle of 2007, he again inched into the top-300, but faded again to close out 2007 at No. 362.

2008
As a qualifier, Marrero reached the final of a Challenger in Chile in January, losing to No. 132 Rubén Ramírez Hidalgo after upsetting No. 272 Sebastián Decoud, No. 187 Adrián García and No. 111 Nicolás Lapentti. This result brought him back into the top 300 at World No. 289. The very next week he gained revenge over Ramirez-Hidalgo to qualify into an ATP stop in Chile, where he again beat García before losing to No. 104 Fabio Fognini in the 2nd round. In February, Marrero scored another upset, defeating World No. 114 Máximo González.
