Silva became the first Cuban woman to reach a world class standard in the pole vault. Her personal bests of 4.90 m (16 ft 3⁄4 in) outdoors and 4.78 m (15 ft 8 in) indoors are the Cuban and Central American and Caribbean records for the event.
Born in Pinar del Río in Cuba, Silva began to participate in pole vault competitions from the age of twelve.[2] Many women in her family took part in athletics and her mother was a javelin thrower.[3] In spite of its strong traditions in track and field, pole vaulting was a discipline in which Cuba had not historically been successful. As a result, Silva quickly established herself nationally at the age of sixteen, coming second at the Cuban Athletics Championships and winning the Barrientos Memorial in 2003.[4] In 2004, she cleared four metres for the first time, which was a Central American and Caribbean junior record. She improved this to 4.10 m at the 2005 Barrientos meet, winning the competition again.[3]
The 2006 season saw her win her first national title and take a third Barrientos Memorial win. She competed internationally for the first time, taking silver at the Central American and Caribbean Games,[5] but failing to clear a height at the 2006 World Junior Championships in Athletics after her poles did not arrive at the competition. Silva ended the season having improved her regional junior record to 4.20 m.[3] In her first year of senior competition she won gold at the 2007 ALBA Games and a bronze at the 2007 Pan American Games. The latter was her country's first medal in the event at the Games and she broke the Central American and Caribbean record with her clearance of 4.30 m. She improved to 4.50 m in early 2008, but a lack of high level competitions meant she managed on 4.15 m in qualifying on her Olympic debut in Beijing.[3]
The 2011 season marked the first time she gained the chance to compete on the international circuit against world class opposition.[3] She competed extensively and had a series of top three finishes across Europe. She broke her personal best on five occasions that year, improving from 4.55 m to 4.75 m over the course of the year.[7]
Silva, coached by Alexander Navas, and her fellow Cuban vaulter Lazaro Borges both emerged as top level athletes in the men's and women's pole vault that year. At the 2011 World Championships in Athletics she came fifth in the final with a regional record vault of 4.70 m, while Borges broke the Cuban record to take the men's silver medal. The pair took gold medals in their events at the end-of-season 2011 Pan American Games, where Silva beat world champion Fabiana Murer with a games record mark of 4.75 m.[3]
Silva began 2013 with a world-leading mark of 4.76 m to win the Pole Vault Stars meeting.[12] She added two centimetres to this mark two weeks later while winning the XL Galan.[13] Returning to Havana for the national championships in March, she vaulted over 4.81 m to add six centimetres to her outdoor best. Taking aim at greater heights, she altered her technique, holding the pole higher and extending her run-up.[14] Silva improved her record again at the Drake Relays on 26 April, winning with 4.85 m and beating Suhr[15] and then cleared 4.90 in Hengelo, Netherlands. She took the bronze medal at the World Athletics Championships in Moscow with a jump of 4.82 m, behind Yelena Isinbayeva and Jennifer Suhr.
