Iván De Jesús Álvarez Jr. (born May 1, 1987)[1] is a Puerto Rican former professional baseball infielder.

[1][11] The Dodgers added him to their 40 man roster prior to the 2010 season and promoted him to the Triple-A Albuquerque Isotopes, where he hit .296 in 130 games.

[12] He played in two games with the Dodgers, striking out five times in seven at-bats before being optioned back to Triple–A Albuquerque on April 6.

With the Cubs batting, his father was performing his third base coaching duties, while Junior entered the game as a defensive replacement.

[16] After being sent back to Triple–A on May 13,[17] and aside from a brief stint in the majors from June 4–6,[18][19] he spent the rest of the season with the Isotopes, hitting .310 with 8 home runs and 59 RBI in 443 plate appearances and 100 games.

[12] DeJesús lost his chance to make the opening day roster in 2012 when he suffered a torn oblique muscle in his side during a spring training game.

[25] On June 1, 2012, DeJesús was part of a Dodgers lineup that featured the sons of five former Major Leaguers (along with Tony Gwynn Jr., Jerry Hairston Jr., Dee Gordon and Scott Van Slyke).

[27] On July 16, 2012, Isotopes manager Lorenzo Bundy decided to start DeJesús in left field.

[30] On August 25, 2012, DeJesús was traded to the Boston Red Sox along with James Loney, Allen Webster and two players to be named later (Jerry Sands and Rubby De La Rosa) for Adrián González, Josh Beckett, Carl Crawford, Nick Punto and $11 million in cash.

[33] With the Red Sox he had 8 at-bats and did not record a hit, striking out 6 times,[12] including the final out of the season.

[54] On January 2, 2018, DeJesús signed a minor league deal with the Boston Red Sox that included an invitation to Spring training.
