Emmanuel Clase Bio
Emmanuel Clase, born March 18, 1998, is a Dominican professional baseball pitcher for the Cleveland Guardians of Major League Baseball (MLB). He made his MLB debut in 2019 with the Texas Rangers and was traded to the Cleveland Indians afterward, becoming their main closer in 2021. Over his career, Clase has established himself as one of the top bullpen arms in the league, earning three All-Star selections and leading the American League in saves on three occasions.
Known for a triple-digit cut fastball and a sharp slider, Clase became the franchise’s all-time save leader with Cleveland. His career has also included challenges, including an 80-game suspension for a positive performance-enhancing drug test in 2020 and a federal indictment tied to a sports betting investigation in 2025.
Early Life and Background
Emmanuel Clase was born on March 18, 1998, in the Dominican Republic. The Dominican Republic has long been a leading source of MLB talent, and Clase entered the professional pipeline as a teenager through the international free agent system. He signed with the San Diego Padres on February 11, 2015, for a $125,000 signing bonus, beginning his path in the United States-based minor leagues.
Clase spent his earliest professional seasons in the Padres’ Dominican and Arizona league affiliates, working his way up the development ladder. In 2015, he pitched for the DSL Padres, going 2–1 with a 1.99 ERA in 54 innings. He split 2016 between the AZL Padres and a brief return in 2017, gradually refining his command and adding velocity.
Path to Baseball
On May 7, 2018, the Padres traded Clase to the Texas Rangers as the player to be named later in an earlier trade for Brett Nicholas. He was assigned to the Spokane Indians of the Low-A Northwest League, where he finished 2018 with a 1–1 record, a 0.64 ERA, 27 strikeouts, and 12 saves in 28+1⁄3 innings. The performance marked him as a relief prospect to watch.
Clase opened 2019 with the Down East Wood Ducks of the High-A Carolina League, going 2–0 with a 0.00 ERA and 11 strikeouts in seven innings before a quick promotion to the Frisco RoughRiders of the Double-A Texas League. At Frisco, he went 1–2 with a 3.35 ERA and 39 strikeouts across 37+2⁄3 innings, showing the swing-and-miss stuff that would soon translate to the major leagues.
Emmanuel Clase Career
Texas Rangers (2019)
The Rangers selected Clase’s contract and promoted him to MLB on August 2, 2019. He made his major league debut on August 4, pitching 1+2⁄3 scoreless innings. Across his rookie season, Clase went 2–3 with a 2.31 ERA and 21 strikeouts over 23+1⁄3 innings, and his cutter averaged 99.2 miles per hour, the fastest in MLB that year.
Cleveland Indians / Guardians (2020–2025)
On December 15, 2019, the Rangers traded Clase and Delino DeShields Jr. to the Cleveland Indians in exchange for Corey Kluber and cash. Clase was suspended for 80 games on May 1, 2020, after testing positive for Boldenone, a banned substance. The suspension was lifted at the conclusion of the pandemic-shortened 60-game season.
Clase returned as a late-inning force in 2021, going 4–5 with a 1.29 ERA and 24 saves in 29 opportunities across 69+2⁄3 innings. In August, he was named AL Reliever of the Month after converting all six save chances and holding batters to a .095 average. On April 2, 2022, Clase agreed to a five-year, $20 million extension with the club, then rebranded as the Cleveland Guardians.
In 2022, Clase earned his first All-Star nod, pitching a scoreless ninth inning at Dodger Stadium to secure a 3–2 American League victory and striking out the side. He finished 3–4 with a 1.36 ERA in 72+2⁄3 innings and led MLB with 42 saves in 46 opportunities, also taking home AL Reliever of the Year honors.
Clase repeated as the majors’ saves leader in 2023, going 3–9 with a 3.22 ERA and 44 saves in 56 chances. In 2024, he made his third All-Star team, closing a 5–3 American League win with a scoreless ninth. On August 30, 2024, he recorded his 150th save for Cleveland, passing Cody Allen to become the franchise’s all-time save leader. He finished 2024 with 47 saves and a sub-1.00 regular-season ERA, then was named AL Reliever of the Year for the second time.
Driving Style and Strengths
Clase features an upper-90s to low-100s mph cut fastball paired with a low-90s slider. As of September 17, 2024, he averaged just 1.6 walks per nine innings, an exceptional level of command for a pitcher throwing at such velocity. The combination of power, movement, and control is the foundation of his late-inning success.
Notable Events and Milestones
Among his signature moments, Clase’s 150th save for Cleveland made him the franchise’s all-time leader, and his 2024 All-Star save in Arlington added another highlight. The 2024 postseason also brought his share of late-inning drama, including a six-out save in Game 5 of the ALDS and difficult moments in the ALCS against the New York Yankees.

2025 Season Performance
The 2025 season opened with Clase as Cleveland’s closer, and through the first half he was 5–3 with a 3.23 ERA and 24 saves in 29 chances over 47+1⁄3 innings. On July 28, 2025, MLB placed him on non-disciplinary paid leave as part of a sports betting investigation, and he did not pitch again that season. Following the season, an attempt to join Estrellas Orientales of the Dominican Professional Baseball League was blocked because the investigation remained active.
On November 9, 2025, federal prosecutors from the U.S. District Court for the Eastern District of New York indicted Clase and teammate Luis Ortiz on charges including wire fraud conspiracy, conspiracy to influence sporting contests by bribery, and money laundering conspiracy. The indictment alleges that Clase and Ortiz agreed in advance with co-conspirators to throw specific types and speeds of pitches, which were then used to place bets. On November 13, 2025, Clase was arrested at JFK Airport in New York City by FBI agents and was arraigned hours later in a Brooklyn federal court, where he entered a plea of not guilty.
As Clase’s legal case proceeds, his on-field status with the Guardians beyond 2025 remains uncertain, with a contract that runs through 2027. The outcome of the federal proceedings is expected to shape both his 2025–2026 outlook and the long-term direction of his career.
