New York Mets claim veteran reliever off waivers

The 33-year-old was first signed by the Washington Nationals as a non-drafted free agent in May 2010, spending three seasons in the Nationals' player development system in the Dominican Republic.

After appearing in 212 minor-league games over eight seasons, Suero was finally called up by the Nationals during the 2018 season on April 30. In 40 outings that season, Suero was impressive, posting a 4-1 record with a 3.59 ERA, 47 strikeouts and a WHIP of 1.22 across 47.2 innings.

The righty would follow up his impressive first season as a big leaguer by leading the Nationals in games pitched and relief innings during the 2019 season. In 78 games, Suero went 6-9 with a 4.54 ERA, 81 punchouts and a 1.26 WHIP in 71.1 innings as Washington went on to win the World Series. Suero would go on to post a 2-0 record with a 3.80 ERA and 28 strikeouts in 22.2 innings during the COVID-shortened 2020 season.

In what would end up being his final season with the Nationals in 2021, Suero struggled, going 2-3 with a 6.33 ERA in 22 games. Washington non-tendered the righty hurler on November 30 of that year, making him a free agent.

Suero would bounce around the league over the next couple of seasons, with the Los Angeles Angels first signing him to a minor league deal on March 31, 2022. He would not appear in any major league games for the Angels during the 2022 season after struggling with the Triple-A Salt Lake Bees, posting a 6.08 ERA with 15 strikeouts. The Angels released Suero on July 8, and he finished the year with the Sultanes de Monterrey of the Mexican League.

During the 2022-23 offseason, he inked a minor league deal with the Los Angeles Dodgers and only made five major league appearances with them, as opposed to 47 appearances with the Triple-A Oklahoma City Dodgers. Suero elected free agency after the 2023 campaign and signed another minors deal with the Houston Astros; once again, he spent most of 2024 in Triple-A and made just one appearance with the Astros on April 9.

The Braves would become Suero's third team in three seasons when they signed him to a minor league contract in December 2024. He began the 2025 season pitching for the Triple-A Gwinnett Stripers, logging a 0-2 record with a 1.50 ERA, 49 strikeouts and 11 saves over 36 innings of work. Atlanta selected his contract on July 11, but Suero struggled mightily; in just five appearances, the 33-year-old had a dismal 11.37 ERA in 6.1 innings before being let go this week.

While Suero has not been a high-leverage reliever over the last couple of seasons, his veteran experience could be something the Mets need for their playoff push as they try to preserve a heavily taxed bullpen.
