Biographical Information

Pitcher Luis Gastélum reached the majors in 2026, a few months after playing for the Mexican national team at the 2026 World Baseball Classic.

He began his pro career with his hometown Cañeros de Los Mochis, going 0-1 with a 3.68 ERA in the 2021-2022 Mexican Pacific League. He had a 3.77 ERA for them the next winter. Signed by the St. Louis Cardinals, he split the summer between the FCL Cardinals (1-2, Sv, 5.19 in 11 G) and Palm Beach Cardinals (0-1, 4.00 in 7 G); he walked only 4 in 26 1/3 innings.That winter, he was 0-1 with a 3.86 ERA for Los Mochis.

Gastélum split 2024 again between the FCL Cardinals (0 R in 3 IP) and Palm Beach (5-2, 8 Sv, 2.81 in 30 G, 70 K, 11 BB in 48 IP). He tied Nolan Santos and Zack Showalter for 4th in the Florida State League in saves and tied for 4th in the Cards chain. For the Cañeros, he had a save and a 1.82 ERA in 24 games, whiffing 37 in 24 2/3 IP. With the '25 Springfield Cardinals, he struck out 92 in 62 2/3 innings and was 3-5 with 10 saves and a 4.02 ERA. He led St. Louis minor leaguers in saves (two ahead of Nick Raquet) while tying for 4th in the Texas League.

The Sinaloa native then made the Mexican national team roster for the 2026 World Baseball Classic. He did not give up a run in two relief appearances. He then started the 2026 season pitching in AAA for the first time, with the Memphis Redbirds of the International League. In 36 relief outings, he was 7-1, 2.27 with 3 saves and only 26 hits allowed in 43 2/3 innings while striking out 49. He was called up to St. Louis on July 8th, replacing Jared Shuster on the roster. He made his big league debut that same day with two-thirds of an inning in relief of Michael McGreevy. He gave up a hit, which allowed an inherited runner to score, completing the 7th inning in a 5-1 loss to the Milwaukee Brewers.
