Emmanuel Rivera Bio
Emmanuel Miguel Rivera (born June 29, 1996) is a Puerto Rican professional baseball third baseman who is currently a free agent. He has previously played in Major League Baseball (MLB) for the Kansas City Royals, Arizona Diamondbacks, Miami Marlins, and Baltimore Orioles. A right-handed-hitting infielder, Rivera is recognized around the league for his glove work at the hot corner and for the nickname “El Pulpo,” a tribute to his late father. Over parts of five big-league seasons, he has served in a variety of roles for his clubs, ranging from everyday starter to late-inning defensive replacement.
Since opening his MLB account in 2021, Rivera has bounced between rosters, taxi squads, and Triple-A affiliates as organizations have shuffled their depth charts. Despite the journeyman pattern of his career, his offensive profile has produced useful stretches, including a brief power surge during his 2024 stint with the Baltimore Orioles. He now enters the 2025–26 offseason as an unsigned free agent.
Early Life and Background
Emmanuel Miguel Rivera was born on June 29, 1996. He grew up in Puerto Rico, where baseball is woven into daily life and where many future professionals cut their teeth on community diamonds and school teams. From an early age, Rivera showed the kind of soft hands and quick reactions that eventually would earn him his enduring nickname, drawing the attention of local coaches who encouraged him to pursue the sport competitively.
Rivera is the son of Miguel Rivera, an amateur baseball player in Puerto Rico who helped shape his son’s love for the game. The bond between father and son ran so deep that Emmanuel adopted the nickname “El Pulpo,” Spanish for “The Octopus,” in homage to Miguel, who was similarly known for his defensive skill. That familial connection to baseball continues to influence how Rivera talks about his own career and the standard he tries to meet on defense.
Rivera attended the Interamerican University of Puerto Rico, where he continued his baseball development while balancing his studies. His play at the school drew the eye of professional scouts, and in 2015 he declared for the MLB Draft.
Path to Professional Baseball
Rivera’s path to professional baseball began when the Kansas City Royals selected him in the 19th round, 579th overall, of the 2015 Major League Baseball Draft out of the Interamerican University of Puerto Rico. Although not a high-profile pick, the selection gave Rivera a direct route into the Royals’ farm system and a chance to prove himself against increasingly difficult competition.
He made his professional debut that summer with the rookie-level Arizona League Royals, appearing in 38 games and getting his first taste of life as a full-time ballplayer. In 2016, Rivera suited up for the rookie-level Burlington Royals, where he posted a .249/.317/.373 slash line in 58 games, refining his approach at the plate while continuing to log innings at third base. The 2017 season brought a promotion to Single-A Lexington, where he broke out with a .310/.364/.468 line, 12 home runs, and 72 RBI, showing the kind of offensive upside that could eventually translate to higher levels.
In 2018, Rivera split time between High-A Wilmington and the AZL Royals, batting a cumulative .274/.326/.416 with 6 home runs and 63 RBI. The next year he advanced to Double-A Northwest Arkansas, where he played 131 games and posted a .258/.297/.345 line with 7 home runs and 57 RBI. The 2020 minor league season was wiped out by the COVID-19 pandemic, but Rivera returned in 2021 with Triple-A Omaha and slashed .282/.337/.593 with a career-high 14 home runs and 40 RBI in only 44 games, forcing Kansas City’s hand and earning him a major league opportunity.
Emmanuel Rivera Career
Early Career and Kansas City Royals (2021–2022)
On June 28, 2021, the Royals selected Rivera to the 40-man roster and promoted him to the majors for the first time. He debuted that same day as the starting third baseman against the Boston Red Sox, picking up his first career hit, a single off starter Garrett Richards. The early excitement was briefly interrupted when Rivera landed on the injured list on June 30 with a left hamate break, but he returned to finish his rookie season playing in 29 games and hitting .256/.316/.333 with one home run, five RBI, and two stolen bases.
In 2022, Rivera appeared in 63 games for Kansas City and slashed .237/.284/.399 with six home runs and 22 RBI, holding down a utility role before the Royals dealt him to the Arizona Diamondbacks on August 1, 2022, in exchange for pitcher Luke Weaver.
Arizona Diamondbacks Era (2022–2023)
Rivera joined Arizona down the stretch of 2022 and played in 39 games for the Diamondbacks, hitting .227/.304/.424 with six home runs and 18 RBI while providing steady defense at third base. He opened the 2023 season with the Triple-A Reno Aces before returning to the majors, where he played 86 games and batted .261/.314/.358 with four home runs and 29 RBI.
Rivera’s most prominent Arizona moment came during the 2023 postseason, when he appeared in 13 games as the Diamondbacks made a run to the World Series. He started three games in the National League Championship Series and Game 4 of the World Series, picking up his first postseason hit as an RBI single in Game 4 of the NLCS. Across 18 playoff plate appearances, he hit .235/.278/.294. On March 28, 2024, Rivera was designated for assignment after failing to make Arizona’s Opening Day roster.
Miami Marlins and Baltimore Orioles Era (2024–2025)
On April 2, 2024, Rivera was traded to the Miami Marlins in exchange for cash. In 96 games for Miami, he slashed .214/.294/.269 with one home run and 15 RBI before the Marlins designated him for assignment on August 19.
Two days later, on August 21, 2024, Rivera was claimed off waivers by the Baltimore Orioles. He made an immediate impact, posting career highs of four hits, four RBI, and 11 total bases with a pair of home runs in a 9–2 away victory over the Minnesota Twins on September 28. In 27 games for Baltimore in 2024, he batted .313/.370/.578 with four home runs and 14 RBI. The 2025 season proved more turbulent. After being designated for assignment in January and shuffled between the majors and Triple-A Norfolk several times, Rivera appeared in 25 games and batted .232/.303/.275 with three RBI and one stolen base before electing free agency on October 6, 2025. He also represented Puerto Rico in the 2023 World Baseball Classic, batting .278 with a triple and five RBI in five games.
Notable Events and Milestones
Rivera’s most memorable major league moment came on September 28, 2024, when he tied career highs with four hits, four RBI, and 11 total bases, slugging two home runs in a 9–2 win at Minnesota. His first career hit, a single off Garrett Richards on debut day in 2021, and his first postseason knock, an RBI single in Game 4 of the 2023 NLCS, both stand out as milestones that bookend his path from 19th-round pick to World Series participant.
Emmanuel Rivera Family
Family Background and Personal Life
Rivera is the son of Miguel Rivera, an amateur baseball player in Puerto Rico whose own defensive skill inspired Emmanuel’s lifelong nickname “El Pulpo.” The nickname has become a rallying point for fans and a small way to honor his father’s influence on his career.

2025 Season Performance
Rivera’s 2025 campaign with the Baltimore Orioles was defined by roster churn rather than steady playing time. He was designated for assignment in late January, cleared waivers, and was sent outright to Triple-A Norfolk on February 10, only to be selected back to the active roster on April 28 after hitting .308 with 13 RBI in 17 games for the Tides. In 25 big-league appearances, he batted .232/.303/.275 with three RBI and one stolen base, struggling to find consistent at-bats as Baltimore reshuffled its infield mix.
The middle of the season saw Rivera bounced between Norfolk and the majors three more times, including brief stints in late June and early July, before the Orioles brought him back for a final run starting August 27. He equaled his career high with four RBI on September 2, 2025, in a 6–2 win at San Diego, and batted .280 with 10 RBI over 16 games down the stretch. Despite the productive finish, he was designated for assignment for a fourth time on September 16 and elected free agency on October 6, closing the book on his Orioles tenure.
