The Detroit Tigers added right-handed pitcher Franklin Perez to their 40-man roster on Monday. Perez, who would have otherwise been eligible to be selected in the 2018 Rule 5 draft, appears to be the team’s lone addition to the 40-man roster ahead of Tuesday’s deadline to protect prospects from being poached by opposing teams in December.
Perhaps more interesting, however, is who was not added to the roster. The Tigers have left outfielder Derek Hill and right-handed pitcher Anthony Castro, among others, unprotected from the Rule 5 draft. Hill, the team’s first round pick in 2014, has only played 357 games across four seasons due to a number of injuries, including Tommy John surgery.
