Oscar Francisco Taveras (June 19, 1992 October 26, 2014) was a Dominican 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.

As a batter, 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, 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.

On May 31, 2014, Taveras homered in his major league debut against the San Francisco Giants and went on to hit .239 in 80 regular season games, playing mostly right field. He also hit a game-tying home run in Game 2 of the 2014 National League Championship Series against the Giants. On October 26, 2014, he died in a car accident in the Dominican Republic shortly after the Cardinals were eliminated from the playoffs.

Early life Originally from Puerto Plata, Dominican Republic, Oscar Taveras grew up in a town called Sosúa. He began taking interest in baseball early in life. According to his father, Francisco Taveras, at about age five, he started to call himself "El Fenómeno," which is Spanish for "The Phenomenon". "He would say, 'I'm going to make you the happiest dad in the world. I want to be a star. I want to be a major leaguer. I'm the phenomenon. I'm the best,'" recounted his father.

Taveras' father was an outfielder in the Milwaukee Brewers' minor league system. Taveras lived in Montreal from ages 12 to 16 and obtained Canadian citizenship. Afterwards, he returned to the Dominican Republic; had he stayed in Canada, he would have entered the draft after high school.

Professional career Minor leagues DSL Cardinals, Johnson City, and Quad Cities (2009–11)

The St. Louis Cardinals signed Taveras as an international amateur free agent on November 25, 2008 for $145,000. They assigned him to the rookie league Dominican Summer League Cardinals the next season. Although he hit just .265 with one home run (HR) and 42 runs batted in (RBI) in 65 games, Taveras earned a promotion to the Johnson City Cardinals of the Rookie-level Appalachian League in 2010. The talent which scouts had discovered in the Dominican Republic quickly actualized, as he hit .322 with eight HR and 43 RBI in 53 games.

Taveras earned another promotion to the Quad Cities River Bandits of the Class A Midwest League (MWL) in 2011 and spent the entire season there. From May 11 to June 11, he was out of action due to a hamstring injury. Despite missing a full month, his hitting continued to improve by obtaining 33 multi-hit games, 17 three-hit contests and five four-hit games. Further, he earned two MWL Player of the Week (PoW) awards. The first was for the week of July 17, after batting .600 (15 hits in 25 at bats) with five multi-hit games, 10 runs scored and five RBI.

The second PoW award Taveras earned with the River Bandits was for the week ending August 28. He batted .581 (18–31) with another five multi-hit games, two home runs and 11 RBI. That week, he also achieved three three-hit games and two four-hit games. After coming off the bench in the August 28 game against Burlington, he went 3-for-3 with a home run and missed hitting for the cycle by a double. For the season, Taveras batted .386 with a .444 on-base percentage (OBP), .584 slugging percentage (SLG), eight HR and 62 RBI in 78 games. He earned the Midwest League batting title with the highest average in the league since 1956. He was actually 31 plate appearances short of qualifying; however, his adjusted batting average after adding the hitless at-bats still gave him the title. He was the first Cardinals minor leaguer to win the MWL batting title since Brendan Ryan in 2004.

Springfield and Memphis (2012–14) After winning the Midwest League batting title at age 19, Taveras began to garner notice outside the Cardinals organization. Baseball America named him the Cardinals' third-best prospect prior to the 2012 season and ranked him 74th in all of baseball.

Entering the 2013 season, Baseball America ranked Taveras as the Cardinals' best prospect and the third-best prospect in all of baseball.

The Cardinals promoted him to the Triple-A Memphis Redbirds of the Pacific Coast League.

In each game from May 6–10, Taveras collected at least one RBI. He batted .362 with 17 hits in 47 at bats for the month of May. However, injury obstructed his in-game action. While sliding into second base in a May 12 game, his ankle caught and pronated awkwardly on the bag, resulting in a high-ankle sprain. He played in just 15 games after that for the season and in 46 total. Surgery to correct the sprain, performed by Dr. Robert Anderson, ended his season in August.

For the season, Taveras rendered a .306 batting average with 12 doubles, five home runs and 32 RBI. It was the fourth consecutive season in which he batted at least .300.

St. Louis Cardinals (2014) Beginning in the 2014 season, MLB.com ranked Taveras as the second-best prospect in all of MLB, behind only Byron Buxton of the Minnesota Twins organization. The Cardinals invited him to spring training. Although team officials believed that his ankle had fully healed in time for 2014 spring training, he hesitated to fully trust the ankle in performance. A hamstring injury followed, limiting him to just six at-bats. The Cardinals optioned him to minor league camp on March 14.

On May 30, 2014, the Cardinals called Taveras up to their MLB roster in one of the most anticipated promotions in all MLB. He became the first from Sosúa to reach the major leagues. At that point, he had been batting .325 with a .373 OBP and a .524 SLG at Memphis. Other totals included seven HR and 40 RBI in 49 games and 191 at-bats. Taveras was held hitless in consecutive games just once. In his last 10 games, he collected hits in all but one, batting .462. During those same 10 games, he fashioned two three-hit games and one four-hit outing. In 209 plate appearances, he walked just 14 times, but also struck out just 25 for a 12.1% strikeout rate.

Making his MLB debut at Busch Stadium on the afternoon of Saturday, May 31, against the San Francisco Giants, Taveras flied out in his first at-bat. However, he launched his first hit and home run, which traveled , in his next at-bat. It occurred with one out in the bottom of the fifth inning against starting pitcher Yusmeiro Petit. He became the youngest to hit a home run in his major league debut for the Cardinals since Eddie Morgan in 1936. It also started to rain, immediately forcing a 47-minute delay. The home run proved to be the game-winning run as the Cardinals won, 2–0.

Taveras hit his first MLB single the next day, June 1. When Matt Adams came off the DL June 19, Taveras' 22nd birthday, the Cardinals optioned him back to Memphis after batting .189 with a .225 OBP and .297 SLG in 40 PA. Despite the low rate statistics, he showed a marked ability to get contact on MLB pitching. His contact rate of 92.3% on pitches outside of the strike zone surpassed the MLB average of 65.7% for all non-pitchers. His miss rate of 2.5% on swinging strikes was significantly lower than the MLB average of 9.1%.
