Andrés Muñoz

Andrés Muñoz Bio

Andrés Clemente Muñoz Apodaca is a Mexican professional baseball pitcher who currently serves as the closer for the Seattle Mariners of Major League Baseball. Born on January 16, 1999, Muñoz has established himself as one of the most dominant relief pitchers in baseball, known for his exceptional fastball velocity that consistently reaches triple digits. He made his major league debut in 2019 with the San Diego Padres and was traded to Seattle in August 2020. Muñoz has earned All-Star honors in 2024 and 2025, and he was named to the All-MLB Second Team in 2025. His journey from international free agent to All-Star closer showcases his resilience, particularly after undergoing Tommy John surgery in 2020 that sidelined him for the entire season.

Early Life and Background

Andrés Muñoz was introduced to baseball at the age of 11 by his grandfather, Damazo, sparking a passion that would define his future. He grew up in Mexico with his parents, Alberto and Maria, alongside two older brothers, Helmond and Miguel. Interestingly, before focusing solely on baseball, Muñoz and his future wife Wendy both competed in track and field as teenagers. This athletic background contributed to the elite-level velocity that would later become his signature on the mound. His family has remained deeply involved in his career, with older brother Helmond and Wendy providing valuable scouting reports on opposing batters throughout his professional career.

Path to Major League Baseball

Muñoz signed with the San Diego Padres as an international free agent on July 7, 2015, receiving a $700,000 signing bonus. He made his professional debut in 2016 with the Arizona Padres of the Rookie-level Arizona League, posting a 1-1 record with a 5.49 earned run average in 16 relief appearances. The following year, he split time between the Tri-City Dust Devils of the Class A Short Season Northwest League and the Fort Wayne TinCaps of the Class A Midwest League, going a combined 3-0 with a 3.81 ERA in 24 relief appearances. After the 2017 season, Muñoz played nine games for the Peoria Javelinas in the Arizona Fall League, where he was the youngest player in the league.

In 2018, Muñoz began the season with Tri-City before earning a promotion to the San Antonio Missions of the Double-A Texas League in late June. He was dominant across both levels, compiling a 2-1 record with a remarkable 0.73 earned run average in just over 24 relief innings. His 2019 season started with the Amarillo Sod Poodles of the Texas League, where he posted a 0-2 record with a 2.16 ERA in 16 and two-thirds innings. His strong performance earned him a promotion to the El Paso Chihuahuas of the Triple-A Pacific Coast League in May 2019, setting the stage for his major league call-up.

Andrés Muñoz Career

San Diego Padres (2019)

On July 12, 2019, the San Diego Padres selected Muñoz’s contract and promoted him to the major leagues. He made his MLB debut that same night against the Atlanta Braves, recording one strikeout and one walk in one inning of work while his fastball topped out at 101.9 miles per hour. Muñoz wasted no time making an impact, earning his first career MLB save on August 29 against the San Francisco Giants, though the moment was memorable for an unusual reason as he allowed an RBI double to his future bullpen coach Stephen Vogt in the ninth inning of a 5-3 victory.

Throughout his rookie season, Muñoz’s four-seam fastball ranked as the second fastest in all of Major League Baseball, averaging 99.9 miles per hour. He finished the 2019 campaign with a record of 1-1 in 22 games, recording 30 strikeouts in just 23 innings. His explosive debut promised a bright future, but that trajectory was temporarily derailed when he underwent Tommy John surgery on March 19, 2020, causing him to miss the entire 2020 season.

Seattle Mariners Breakthrough (2021–2023)

On August 30, 2020, the Padres traded Muñoz to the Seattle Mariners as part of a major trade that sent Ty France, Taylor Trammell, and Luis Torrens to Seattle in exchange for catcher Austin Nola and relievers Dan Altavilla and Austin Adams. Muñoz continued his recovery from Tommy John surgery into February 2021, requiring him to remain on the 60-day injured list. After making four rehabilitation appearances in the minor leagues, he returned to make his Mariners debut in the team’s final game of the 2021 season.

Muñoz returned to a setup role in 2022, working with several other relievers generally ahead of closer Paul Sewald. He recorded a 2-5 record with four saves and a 2.45 earned run average, striking out 96 batters in 65 innings. His fastball averaged 100.2 miles per hour, but his slider emerged as his most effective pitch, with opposing batters hitting only .126 against his breaking ball. Perhaps most importantly, his control improved dramatically, as he walked only 6 percent of batters faced, well below the MLB average. While he pitched in every Mariners postseason game that year, he struggled in the American League Division Series against the Houston Astros, allowing three runs in three innings.

Seattle Mariners Era (2023–Present)

Injuries hampered Muñoz at the start of the 2023 season. A right deltoid strain placed him on the 10-day injured list on April 9, and shoulder inflammation kept him sidelined until June 6. Ankle surgery also disrupted his offseason preparation. Despite these setbacks, Muñoz seized an opportunity when the Mariners dealt Paul Sewald at the 2023 trade deadline, taking over as the team’s closer. He excelled in the higher-leverage role, earning American League Reliever of the Month honors for August. After recording just two saves through the end of July, he accumulated 11 more saves following the Sewald trade, finishing the season with a 4-7 record and 67 strikeouts in 49 innings across 52 games.

Muñoz’s breakthrough year came in 2024. On July 12, he was named to the All-Star Game as a replacement for teammate Logan Gilbert, though he did not pitch in the exhibition. More impressively, he did not allow a hit in 12 consecutive appearances from July 5 to August 14, breaking a franchise record while yielding no runs during that streak. He finished the season with a career-high 22 saves, a 3-7 record, and a 2.12 earned run average, striking out 77 batters in 59 and one-third innings.

The 2025 season saw Muñoz continue his dominant form. After beginning the year with 15 straight scoreless appearances, including 11 saves, he earned American League Reliever of the Month honors for March and April. His performance earned him a spot on the 2025 All-Star Game roster, marking his second consecutive selection. Through late June 2026, Muñoz has compiled a career record of 16 wins and 27 losses with a 2.68 earned run average, 400 strikeouts, and 93 saves across his major league career.

Driving Style and Strengths

Muñoz’s effectiveness centers on his exceptional fastball velocity, which has consistently averaged over 99 miles per hour throughout his career. His four-seam fastball ranks among the hardest-thrown pitches in baseball, and he has developed a slider that has become his most effective secondary offering, with opposing batters posting remarkably low batting averages against the breaking ball. His ability to miss bats and generate swing-and-miss results has made him a reliable option in high-leverage situations, whether as a setup man or closer.

Notable Events and Milestones

Among Muñoz’s career highlights, his consecutive hitless appearances streak of 12 games in 2024 stands out as a franchise record for the Seattle Mariners. His 22 saves in 2024 represented a career high at that point, while his 93 career saves through mid-2026 demonstrate his sustained excellence. The signing of his four-year, $7.5 million contract extension in December 2021, with potential options worth up to $24 million additional, reflects the organization’s commitment to him as a cornerstone of their bullpen. His two All-Star selections in 2024 and 2025, combined with his All-MLB Second Team recognition in 2025, underscore his status among the league’s elite relievers.

Andrés Muñoz Career Wins

Muñoz has established himself as a durable and reliable closer throughout his major league career, accumulating 93 career saves through late June 2026. His 16-27 win-loss record reflects his role as a closer rather than a starter, where wins are less frequent but losses can accumulate when inherited runners score. His 2.68 career earned run average and 400 strikeouts demonstrate his ability to miss bats and keep opposing teams off the scoreboard.

Seattle Mariners Highlights

Muñoz’s tenure with the Seattle Mariners has been defined by continuous improvement and eventual dominance. His transition from setup reliever to closer following the Paul Sewald trade in 2023 marked a turning point in his career. The American League Reliever of the Month awards he earned in August 2023 and March/April 2025 recognize his sustained excellence. His 22 saves in 2024 represented a significant milestone, while his 2025 All-Star selection and All-MLB Second Team honor validate his status as one of baseball’s premier closers. The Mariners’ investment in him through his contract extension reflects their belief in his long-term value to the organization.

Other Wins and Performances

Beyond his save totals, Muñoz has accumulated clutch performances throughout his career. His 2022 postseason appearance, including the series-clinching victory in Game 2 of the Wild Card Series against the Toronto Blue Jays, demonstrated his ability to perform on the biggest stage. His 96 strikeouts in 2022 and 77 strikeouts in 2024 highlight his capacity to generate whiffs even in limited appearances. As a former international free agent from Mexico, he represents the growing presence of Mexican-born players in Major League Baseball’s bullpen corps.

Andrés Muñoz Family

Family Background and Racing Lineage

Muñoz comes from a supportive family background that has been instrumental in his baseball career. His father Alberto and mother Maria have followed his professional journey closely. His grandfather Damazo introduced him to baseball at age 11, a formative experience that ignited his passion for the sport. He has two older brothers, Helmond and Miguel, with Helmond providing scouting reports on opposing batters alongside Muñoz’s wife Wendy. This family involvement in his career extends beyond emotional support to active participation in his development as a pitcher.

Personal Life

Muñoz married his wife Wendy in July 2022 during the All-Star break, marking the beginning of their married life together. The couple first met as teenagers when they both competed in track and field, demonstrating their long-standing relationship that predates his professional baseball career. They share their lives with a pet cat named Matilda, who joins them on road trips throughout the baseball season. Despite the demands of a professional baseball career, Muñoz maintains strong personal connections with his family, with his brother Helmond and wife Wendy contributing to his preparation by offering detailed scouting reports on hitters he will face.

2025 Season Performance

The 2025 season represented another milestone year in Muñoz’s career as he solidified his status as one of the American League’s premier closers. Named to his second consecutive All-Star Game roster, he continued the dominant form that characterized his 2024 campaign. His early-season performance was particularly impressive, as he began the year with 15 consecutive scoreless appearances, converting 11 of those into saves during that stretch. This exceptional start earned him American League Reliever of the Month honors for March and April, matching the same award he achieved in August 2023.

Working alongside a rotation of setup relievers, Muñoz served as the anchor of the Mariners’ bullpen throughout the season. His ability to handle high-pressure situations with poise made him a reliable option for manager Dan Wilson in late-inning scenarios. The continued development of his secondary pitches, particularly his slider, gave hitters fits and contributed to his effectiveness against both left-handed and right-handed batters.
