Cleveland Indians / Guardians Vargas was signed by the
Cleveland Indians as an international free agent on July 2, 2016. He made his professional debut in 2018 with the rookie-level
Arizona League Indians, for whom he pitched to a 3.93 ERA across 10 games (9 starts). In 2019, Vargas made 15 starts for the Low-A
Mahoning Valley Scrappers, registering a 6–4 record and 4.52 ERA with 71 strikeouts across innings of work. He did not play in a game in 2020 due to the cancellation of the minor league season because of the
COVID-19 pandemic. On November 20, 2020, the Indians added Vargas to their
40-man roster to protect him from the
Rule 5 draft. In April 2021, Vargas underwent
ulnar collateral ligament reconstruction (Tommy John surgery), causing him to miss the entire 2021 season. He began the 2022 season on the rebranded Cleveland Guardians' major league 60-day
injured list as he continued to recover from surgery. Vargas was activated from the injured list on July 18, 2022, and optioned to the
Double-A Akron RubberDucks. He was promoted to the
Triple-A Columbus Clippers on September 3. The Guardians promoted Vargas to the major leagues for the first time on September 16, 2022. He was optioned back to Columbus on September 20 without having made an appearance for the Guardians, becoming a
phantom ballplayer.
Arizona Diamondbacks 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. In five major league appearances for Arizona, he logged a 5.79 ERA with seven strikeouts across innings. The Diamondbacks
optioned Vargas to the Triple-A
Reno Aces on April 12, where he spent the remainder of the year.
Seattle Mariners On November 22, 2023, the Diamondbacks traded Vargas and catcher
Seby Zavala to the
Seattle Mariners in exchange for third baseman
Eugenio Suárez. He was optioned to the Triple-A
Tacoma Rainiers to begin the 2024 season. In 55 appearances for Tacoma, Vargas had a 2–5 record and 3.54 ERA with 40 strikeouts and two saves across innings pitched. Vargas made the Mariners' 2025 Opening Day roster. In 70 games, he had 5–5 record and 3.97 ERA, earning his first major league save on May 6. 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. ==References==
