Keegan Thompson was once believed to be a fixture in the Chicago Cubs' bullpen, finishing the 2022 season as a high-leverage relief pitcher who could pitch multiple innings. Command issues have plagued Thompson since then, who spent most of his time with the Iowa Cubs over the last three seasons. Thompson didn't make an appearance at the Major League level with the Cubs last season and elected free agency shortly after the season ended.
Given his status as a minor-league free agent, Thompson was eligible to sign with a new team as soon as he saw fit.
