Early Life and Background
Carlos Miguel Vargas was born on October 13, 1999, in the Dominican Republic. He grew up in a baseball-loving region where young players often develop their skills through community leagues and informal games. The Dominican Republic has produced countless MLB stars, and Vargas began playing baseball at a young age, honing the fundamentals that would later define his pitching style.
Vargas was signed by the Cleveland Indians as an international free agent on July 2, 2016, when he was just 16 years old. His youth and projectable frame attracted scouts who saw potential for development over time. The signing marked the beginning of his journey toward becoming a professional pitcher in the American baseball system.
Path to Major League Baseball
After signing with Cleveland, Vargas made his professional debut in 2018 with the rookie-level Arizona League Indians. He appeared in 10 games, making nine starts, and posted a 3.93 earned run average (ERA) across the season. The experience provided him with invaluable exposure to professional competition and helped him adjust to the rigors of organized baseball.
Vargas continued his development in 2019 with the Low-A Mahoning Valley Scrappers, where he made 15 starts. He recorded a 6-4 win-loss record with a 4.52 ERA and recorded 71 strikeouts across 77 and two-thirds innings. The season represented a solid step forward in his progression through the minor leagues. The following year, however, Vargas did not play due to the cancellation of the minor league season caused by the COVID-19 pandemic.
Carlos Miguel Vargas Career
Cleveland Guardians Organization (2016-2022)
Vargas was added to the Cleveland Indians 40-man roster on November 20, 2020, a move designed to protect him from the Rule 5 draft. The recognition signaled the organization’s belief in his potential as a future major league contributor. In April 2021, Vargas underwent ulnar collateral ligament reconstruction surgery, commonly known as Tommy John surgery, which forced him to miss the entire 2021 season.
He began the 2022 season on the rebranded Cleveland Guardians’ 60-day injured list as he continued his recovery from surgery. Vargas was activated from the injured list on July 18, 2022, and was optioned to the Double-A Akron RubberDucks. He was promoted to the Triple-A Columbus Clippers on September 3, 2022. The Guardians promoted Vargas to the major leagues for the first time on September 16, 2022, though he was optioned back to Columbus on September 20 without making an appearance, becoming a phantom ballplayer.
Arizona Diamondbacks (2023)
The Guardians traded Vargas to the Arizona Diamondbacks on November 15, 2022, in exchange for minor league pitcher Ross Carver. Vargas made the Diamondbacks’ 2023 Opening Day roster, achieving his goal of appearing in a major league regular season game. In five MLB appearances for Arizona, he logged a 5.79 ERA with seven strikeouts across four and two-thirds innings. The Diamondbacks optioned Vargas to the Triple-A Reno Aces on April 12, where he spent the remainder of the season, continuing to refine his craft in the minor leagues.
Seattle Mariners (2025-Present)

In 55 appearances for Tacoma, he had a 2-5 record and 3.54 ERA with 40 strikeouts and two saves across 53 and one-third innings pitched. The strong minor league performance earned him consideration for a major league roster spot.

He earned his first major league save on May 6, 2025, a milestone that represented years of work to reach the highest level of the sport. Vargas was placed on the injured list to begin the 2026 season due to a lat strain. He was transferred to the 60-day injured list on April 8, 2026.
