Miguel Lugo of TUDN Sinaloa and Liga ARCO Mexicana del Pacifico franchise, Tomateros de Culiacán reporter stated on May 14 that Seattle Mariners right-handed closer Andres Munoz will play for Mexico in the 2026 World Baseball Classic.

Mexico will face the United States, Italy, Great Britain, and Brazil in Pool B at Daikin Park in Houston, Texas from March 6–11.

The 26-year-old from Los Mochis, Mexico currently leads Major League Baseball with 13 saves and has not allowed an earned run to start the 2025 season.

Munoz has thrown 19 innings across 19 games, finishing 14 of them, with a 1-0 record. He has allowed just seven hits and eight walks while striking out 26 batters heading into May 15.

During the 2025 Cactus League season, Munoz made seven appearances, posting a 3.86 ERA in seven innings with six hits, three earned runs, no home runs, one hit batter, three walks, and seven strikeouts.

He was named an All-Star for the first time in 2024, when he went 3-7 with a 2.12 ERA over 60 relief appearances. He recorded 22 saves, threw 59.1 innings, allowed 31 hits, 14 earned runs, six home runs, 26 walks, and struck out 77 batters with a 0.961 WHIP.

Munoz is in his fifth season with the Mariners after being traded from the San Diego Padres on August 30, 2020. The deal sent Munoz, Ty France, Taylor Trammell, and Luis Torrens to Seattle in exchange for Austin Nola, Dan Altavilla, and Austin Adams.

Over his MLB career with San Diego in 2019 and Seattle since 2021, Munoz has appeared in 218 games, posting a 2.42 ERA and 11-20 record with 53 saves. He has thrown 216 innings, allowing 137 hits, 58 earned runs, 15 home runs, 84 walks, and striking out 297 batters with a 1.023 WHIP.

According to Baseball Savant, Munoz relies on his slider 49.8 percent of the time, followed by a four-seam fastball at 35.4 percent, a sinker at 13.8 percent, and a changeup at 1.0 percent.

His slider generates a 32.8 percent putaway rate and a 55.7 percent whiff rate. His sinker averages 98.2 mph, while his four-seamer averages 98.7 mph.

The 23-19 Seattle Mariners will begin a three-game interleague road series against the 26-15 San Diego Padres at 9:40 p.m. EDT on May 16.
