Oscar Francisco Taveras (June 19, 1992 – October 26, 2014) was a Dominican–Canadian professional baseball outfielder who played one season for the St. Louis Cardinals of Major League Baseball (MLB). Known as "El Fenómeno" (Spanish for "The Phenomenon") in the Dominican Republic, the Cardinals signed him at age 16 in 2008 as an international amateur free agent and he made his MLB debut in 2014. Over six minor league seasons, he batted .321 with a .519 slugging percentage. He played all three outfield positions while spending most of the time in center field.
With prodigious batting skills, Taveras was a consensus top-five minor league prospect in 2013 and 2014. He elicited comparisons to former MLB outfielder and fellow Dominican Vladimir Guerrero – with a powerful and smooth, balanced stroke, Taveras successfully hit pitches well outside of the strike zone. Also similar to Guerrero, he possessed a strong and accurate throwing arm. The outfielder was the recipient of a litany of awards and won batting titles in two minor leagues, including hitting .386 for the Midwest League title in 2011. The next year, he won the Texas League batting title and was the Texas League Player of the Year and Cardinals organization Player of the Year.
