The Minnesota Twins designated right-hander Simeon Woods Richardson for assignment Saturday after a disastrous 0-7 start to the season.
Richardson, 25, leads the major leagues in losses and leads the American League in earned runs allowed (41).
His ERA swelled to 7.74 in Thursday’s 6-2 road loss to the Chicago White Sox when he allowed five runs on five hits in 2 2/3 innings. He has struck out 26 batters, walked 25 and surrendered nine homers in 47 2/3 innings. Opponents are batting .330 against him with a .952 OPS in 12 games (10 starts).
Richardson is 12-17 with a 4.76 ERA in 65 career games (61 starts) since making his major league debut with the Twins in 2022.
Minnesota recalled right-hander John Klein from Triple-A St. Paul in a corresponding move. Klein, 24, made his MLB debut on May 2 and is 0-1 with a 7.71 ERA in two relief appearances for the Twins.
