On June 26, 1983, in a game where his Seattle Mariners were trailing the Toronto Blue Jays 12-3, infielder Manny Castillo was brought in to pitch by manager Del Crandall. Castillo had a strong throwing arm, but facing major league hitters he had a rough time of it. Facing 19 batters over the course of 2 2/3 innings, Castillo allowed eight hits and three walks. He surrendered back-to-back home runs to Mickey Klutts and Rance Mulliniks in his first inning of work and then allowed another home to Klutts later. His ERA for his brief big league pitching career was 23.63.
Castillo was a standout at several of his stops in the minor leagues, hitting .294 in 963 games in the minors over 14 seasons before and after his three-year major league stint. In 1981 at Triple-A Omaha in the Royals’ farm system, Castillo hit .335 with 182 hits, 10 homers, and 91 RBI as he was named MVP of the American Association. But as a third baseman he wasn’t going to crack the lineup in Kansas City with George Brett ensconced at third base, so he was dealt to the Seattle Mariners after the ’81 season. Playing regularly at third base for the M’s in 1982, Castillo struggled at the plate and in the field, making 20 errors at the hot corner. In 1983 he had difficulty keeping his batting average above .200 and found himself platooning at third base. It was his final season as a major league ballplayer.
The Mariners received Castillo from Kansas City for a player to be named later in October of 1981. The player they later sent to the Royals was left-handed pitcher Bud Black, who spent seven seasons with KC, winning 56 games and serving as part of the rotation in 1985 on the team that won the World Series.
