Former Auburn pitcher Bailey Horn joined the St. Louis Cardinals as waiver claim on Thursday, the National League team announced, and was added to its 40-man roster.

Horn pitched in 18 games for the Boston Red Sox in 2024, but the Cardinals got the left-hander from the Detroit Tigers, who had obtained him on Nov. 22.

Horn made his Major League debut out of the Red Sox bullpen on June 29, called up from Triple-A Worcester, where he had a 1-2 record with a 1.69 earned-run average and one save in 12 relief appearances. In 16 innings, Horn struck out 19 while yielding nine hits and nine walks.

With Boston, Horn had a 1-1 record with a 6.50 earned-run average. In 18 innings, he struck out 13 and walked 10.

The Cardinals obtained Horn even though they have three left-handers who made at least 54 relief appearances last season – JoJo Romero with 65, John King with 56 and Matthew Liberator with 54.

Horn pitched at Auburn in 2019 and 2020. He had a 7-3 record with a 4.75 ERA in 22 games, including nine starts. In 55 innings, Horn struck out 58 while yielding 51 hits and 25 walks.
