The Cardinals optioned Horn to Triple-A Memphis on Sunday, Derrick Goold of the St. Louis Post-Dispatch reports.

EDGE Analysis

The left-hander was claimed off waivers by St. Louis in January but won't end up making the Opening Day roster. Horn made his MLB debut with the Red Sox last season and had a 6.50 ERA, 1.78 WHIP and 13:10 K:BB over 18 innings.

The Cardinals claimed Horn off waivers from the Tigers on Thursday, John Denton of MLB.com reports.

EDGE Analysis

Horn was pushed off Detroit's 40-man roster in December to create space for Gleyber Torres, putting an end to Horn's tenure with the Tigers after just over a month. The 26-year-old southpaw turned in a 6.50 ERA and 1.78 WHIP across 18 innings with the Red Sox last season, and barring a major turnaround during spring training, he'll most likely report to Triple-A Memphis to begin 2025.

The Tigers designated Horn for assignment Friday.

EDGE Analysis

The move frees up a spot on the 40-man roster for the newly-signed Gleyber Torres. Horn was claimed off waivers by the Tigers in November and the left-handed reliever will now go through the waiver process again.

EDGE Analysis

The Red Sox attempted to pass Horn through waivers in an effort to clear space on their 40-man roster, but the 26-year-old southpaw will instead head to Detroit and look to carve out a role for himself with the Tigers. However, he struggled to the tune of a 6.50 ERA and 1.78 WHIP over 18 innings in 2024, so he'll most likely report to Triple-A Toledo to begin the new season.

EDGE Analysis
