Here is Adrian Sampson's transaction journey for this year:
March 19, 2022: Signed as a Free Agent with the Chicago Cubs.
May 13, 2022: Selected off waivers by the Seattle Mariners from the Chicago Cubs.
May 25, 2022: Granted Free Agency.
May 31, 2022: Signed as a Free Agent with the Chicago Cubs.
And today, he's back with the MLB Cubs after his second stint with Triple-A Iowa.
To make room for Sampson on the 40-man roster, lefthander Eric Stout was designated for assignment.
Stout was the only Cubs pitcher who threw well Wednesday, striking out four. I suspect he'll clear waivers and be back at Iowa.
Sampson pitched in one game for the Cubs earlier this year and has a 3.81 ERA in eight outings (six starts) for Iowa.
