Prior to the 2019 season, the Phillies signed reliever David Robertson to a two-year contract. He immediately became the roster’s best-looking player, but unfortunately his on-field performance wasn’t much to look at. He pitched ineffectually in seven games before a ligament tear required him to undergo Tommy John surgery, forcing him to serve out the remainder of his deal on the Injured List.
After returning to the majors in 2021, Robertson signed with the Cubs as a free agent prior to the 2022 season. Serving as their closer, he pitched well; so well, that when the Phillies sought midseason relief help, they identified Robertson as an option.
