T. J. Rivera

Rivera continued to struggle with his rehabilitation during spring training in 2019. On March 9, the Mets released Rivera.

Rivera was signed by the Long Island Ducks of the Atlantic League on July 6, 2019. On August 4, 2019, Rivera's contract was purchased by the Washington Nationals. He became a free agent following the 2019 season.

On December 15, 2019, Rivera signed a minor league deal with the Philadelphia Phillies.

Rivera was born to Tommy, a handyman, and Nilsa Rivera, an insurance adjuster. Rivera is of Puerto Rican descent. His mother and father are from Aibonito and Ponce, Puerto Rico. He represented Puerto Rico at the 2017 World Baseball Classic. Rivera grew up as a fan of the New York Yankees, but also liked the Mets. Rivera met his wife, Ashton, at Troy University.

In 2017, Rivera was named to his first ever Major League Opening Day roster. He was sent down to AAA on June 11 to make room for Yoenis Céspedes, but recalled on June 13 after Asdrúbal Cabrera went on the disabled list. The Mets placed Rivera on the 10-day disabled list on July 28, after a partial tear in his right ulnar collateral ligament. He underwent Tommy John surgery towards the end of the 2017 campaign. He hoped to return to the Mets around midseason, but an elbow sprain suffered while playing rehabilitation games in the minor leagues ended his season. He recorded 22 plate appearances in the minor leagues during the 2018 season.

Rivera played for the Puerto Rican national baseball team in the 2017 World Baseball Classic as their first baseman.

The Mets invited Rivera to spring training in 2016. He began the 2016 season with Las Vegas. He was named the PCL's Player of the Month for May, when he batted .373 with five home runs. He ended the season as the PCL batting champion.

Rivera attended Herbert H. Lehman High School in eastern Bronx. After attending tryouts using a softball glove and playing junior varsity his freshman year, he went on to play varsity for three seasons while batting over .600 his junior and senior years. Rivera began his college baseball career at Fairleigh Dickinson University in New Jersey where he then transferred to Wallace Community College in the Alabama Community College Conference, in Dothan, Alabama. Rivera chose Wallace in order to play against tougher competition in warmer weather. After two seasons, Rivera transferred to Troy University in Troy, Alabama, where he played for the Troy Trojans. He graduated from Troy in 2011 majoring in criminal justice, but went unselected in the Major League Baseball draft.

Rivera had a .301 batting average in 2011, splitting the season between the Kingsport Mets of the Rookie-level Appalachian League and the Brooklyn Cyclones of the Class A-Short Season New York–Penn League. In 2014, Rivera hit .349 with five home runs and 75 runs batted in (RBIs) for the St. Lucie Mets of the Class A-Advanced Florida State League and the Binghamton Mets of the Class AA Eastern League. He returned to Binghamton to start the 2015 season, and was promoted to the Las Vegas 51s of the Class AAA Pacific Coast League (PCL) on May 16. Despite hitting .306 with 17 doubles in 54 games, the Mets demoted Rivera to Binghamton on August 1. The Mets chose not to add Rivera to their 40-man roster after the 2015 season, exposing him to the Rule 5 draft; he went unselected.

Rivera grew up in the Throgs Neck neighborhood of the Bronx. He played in local little leagues in Throgs Neck and Parkchester, and often played sports including baseball on concrete fields or in the street. In 2001 at the age of 12, Rivera played in a Little League district championship, eliminated by Danny Almonte and the "Baby Bombers" who went on to the Little League World Series. (The Baby Bombers had their wins wiped out retroactively due to the Almonte fraud.)

Thomas Javier Rivera (born October 27, 1988) is an American professional baseball infielder for the Philadelphia Phillies organization. He played for the New York Mets of Major League Baseball (MLB) in 2016 and 2017. Rivera is a native of New York City, and went undrafted after playing college baseball at Troy University. He made his MLB debut in 2016, and played for the Puerto Rican national baseball team in the 2017 World Baseball Classic.
