Paul Campbell

A 21st-round pick by the Rays in 2017, Campbell was not seen publicly on a baseball field in 2020 after dealing with a forearm strain early in the calendar year. Regardless the Marlins took Campbell in December's Rule 5 draft. Campbell had a nice season between High-A and Double-A in 2019, and Eric Longenhagen of FanGraphs noted that the righty can spin his fastball a great deal (2650 rpm on average in 2019) despite middling velocity. That spin has not led to many strikeouts and it's questionable whether the Marlins will be able to keep Campball on the big-league roster all year. By rule, the Marlins will have to keep him on the roster or else offer him back to the Rays. Campbell is going to be 26 this summer and may be able to hold his own better than a lot of Rule 5 picks, but he will likely play a minimal role if he's even on the club, working mostly in mop-up duty.
