Andres Munoz’s right arm has taken him from Los Mochis, Mexico, to Fort Wayne, Ind., to three stops in Texas — San Antonio, Amarillo and now El Paso. The Padres on Tuesday promoted the 20-year-old reliever to the Triple-A Pacific Coast League. In 15 games at Double-A Amarillo, Munoz — who has been clocked as high as 104 mph this year — struck out 32 batters and held opposing hitters to a .130 batting average over 15 2/3 innings (1.72 ERA). His mid-80s slider a focus in recent weeks, Munoz had posted a 25-to-4 strikeout to walk ratio over 11 2/3 straight scoreless innings to earn the promotion. The Padres signed Munoz out of Mexico in 2015 in July 2015 for $700,000. He finished 2018 at Double-A San Antonio a year after he was the youngest player invited to the Arizona Fall League, a finishing school of sorts for the game’s top prospects. MLB.com ranks Munoz No. 21 in the Padres’ farm system. His promotion to Triple-A El Paso was paired with activating right-hander Michel Baez off Amarillo’s injured list. Baez was expected to pitch in relief on Tuesday as he continues to build his pitch count.
