He has previously played in Major League Baseball (MLB) for the New York Mets, Texas Rangers, Seattle Mariners, Houston Astros, Atlanta Braves, and Detroit Tigers. A right-handed reliever, Montero is best known for earning a World Series championship ring with the Houston Astros in 2022.

Across his MLB career through the 2025 season, he has compiled a 23-30 win-loss record, a 4.68 earned run average, 517 strikeouts, and 30 saves.

Early Life and Background
Rafael Montero was born on October 17, 1990, and grew up in the Dominican Republic, a country that has produced generations of Major League Baseball talent. From an early age he developed an interest in pitching, and his progression through local baseball programs helped him attract the attention of professional scouts.
Although his family background is not widely documented, his career path reflects the typical journey of a young Dominican prospect who works his way through amateur and international competition. By the time he was nearing his 21st birthday, Montero had developed into one of the most talked-about young pitchers in his region.
His education outside of baseball is not publicly documented in major sources. Instead, his development came primarily through the Mets’ international scouting and development system, which identified him as a top amateur pitching prospect.
Path to Baseball
Montero signed with the New York Mets as an international free agent on January 20, 2011. He signed at a much older age than most Dominican players, which made his rapid rise through the minor leagues especially impressive. In his first professional season, he went 5-4 with a 2.15 earned run average and 66 strikeouts across 71 innings pitched.
The 2012 season was even stronger for Montero. He posted an 11-5 record with a 2.36 ERA, 110 strikeouts, and only 19 walks in 122 innings. Prior to the 2013 season, Baseball America ranked him as the Mets’ fifth-best prospect, signaling that his big-league debut was approaching. He split that year between Double-A Binghamton and Triple-A Las Vegas, finishing with 150 strikeouts in more than 155 innings.
Rafael Montero Career
Early Career (2014-2017)
Montero made his MLB debut on May 14, 2014, starting against the New York Yankees at Citi Field. He recorded his first major league strikeout by getting Derek Jeter on a 3-2 fastball and pitched six innings in the contest. He shuttled between the majors and Triple-A that year and finished with a 1-3 record and 4.06 ERA in 10 games.
After injuries limited him in 2015, Montero returned to the Mets’ bullpen and rotation mix in 2016 and 2017. In 2017, he made 34 appearances including 18 starts, posting a 5-11 record and a 5.52 ERA with 114 strikeouts over 119 innings. He underwent Tommy John surgery after the season and missed all of 2018, electing free agency in November of that year.
Texas Rangers Breakthrough (2019-2020)
On December 4, 2018, Montero signed a minor league contract with the Texas Rangers and worked his way back from surgery across the rookie, Double-A, and Triple-A levels. The Rangers selected his contract on July 22, 2019, and he appeared in the majors that summer. With Texas in 2019, he went 2-0 with a 2.48 ERA and 34 strikeouts across 29 innings, showing that he was fully recovered and effective.
In the 2020 pandemic-shortened season, Montero took on a relief role and produced eight saves in eight opportunities, his first major league saves. He finished the year with a 4.08 ERA, a 1.02 WHIP, and 19 strikeouts in 17⅔ innings, re-establishing himself as a reliable late-inning arm.
Seattle Mariners Era (2021)
On December 15, 2020, Montero was traded to the Seattle Mariners in exchange for Jose Corniell and a player to be named later, Andres Mesa. In 40 games for the Mariners he struggled to a 7.27 ERA with 37 strikeouts, and on July 23, 2021, he was designated for assignment.
Houston Astros Era (2021-2025)
Montero was traded to the Houston Astros on July 27, 2021, along with Kendall Graveman, in exchange for Abraham Toro and Joe Smith. After four scoreless appearances with Houston, he avoided arbitration in March 2022 by agreeing to a $2.275 million contract. That season became the defining year of his career: he made 71 relief appearances, posted a 2.37 ERA, recorded 14 saves, and went 5-2 over 68⅓ innings, ranking third in the American League in pitching appearances.
Montero made his postseason debut on October 11, 2022, in Game 1 of the ALDS against the Seattle Mariners, earning the win in an 8-7 walk-off victory. He appeared in every game of that series and pitched 3⅓ shutout innings. On November 2, 2022, he relieved Bryan Abreu in the eighth inning of Game 4 of the World Series, helping preserve a combined no-hitter finished by Ryan Pressly. The Astros defeated the Philadelphia Phillies in six games, giving Montero his first World Series title.
On November 15, 2022, Montero re-signed with Houston on a three-year, $34.5 million contract. He struggled in 2023 with a 5.08 ERA across 68 appearances and was designated for assignment in July 2024 before being outrighted to Triple-A Sugar Land. With the Sugar Land Space Cowboys he posted a 2.20 ERA and helped the club win the Pacific Coast League championship and the Triple-A National Championship Game, both firsts for Sugar Land. He returned to the Astros’ Opening Day roster in 2025 before being traded.
Atlanta Braves and Detroit Tigers Era (2025)
On April 8, 2025, the Astros traded Montero and cash considerations to the Atlanta Braves in exchange for Patrick Halligan. In 36 games for Atlanta he pitched to a 5.50 ERA with 34 strikeouts across 34⅓ innings. On July 30, 2025, the Braves traded him to the Detroit Tigers in exchange for Jim Jarvis. With Detroit, he made 20 relief appearances and posted a 2.86 ERA with 19 strikeouts across 22 innings, providing late-season stability in the bullpen.
Driving Style and Strengths
Montero relies on a power arm built around a fastball-slider combination, and he has worked to refine his changeup by lowering its velocity at the Astros’ direction while leaning more heavily on his slider. His greatest strength has been his durability and willingness to pitch on back-to-back days, which has made him a trusted setup and save option in high-leverage moments.
Notable Events and Milestones
The signature moment of Montero’s career came on November 2, 2022, when he helped preserve a combined no-hitter in Game 4 of the World Series against the Philadelphia Phillies. He also recorded his first career double-digit save total in 2022, joined Houston’s bullpen during a championship run, and contributed to Sugar Land’s first Pacific Coast League and Triple-A National Championships in 2024.

Other Wins and Performances
At the minor league level, Montero has excelled at every stop, including a 12-7 season across Double-A and Triple-A in 2013 and a 1-1 record with a 2.20 ERA at Sugar Land in 2024, where he helped the Space Cowboys win the Pacific Coast League championship and the Triple-A National Championship Game.

2025 Season Performance
The 2025 season was one of transition for Rafael Montero, who began the year with the Houston Astros after making the Opening Day roster. He recorded a 4.50 ERA with five strikeouts across four innings in three appearances before being traded on April 8 to the Atlanta Braves in exchange for Patrick Halligan. With Atlanta he appeared in 36 games but struggled to a 5.50 ERA across 34⅓ innings, leading to another trade.
