Perdomo is off the Padres’ roster as they prepare for this winter’s Rule 5 Draft, but he actually first joined the team as a Rule 5 selection from the Rockies before the 2015 campaign. Perdomo has since given the 444 1/3 innings of 5.19 ERA/4.44 FIP ball with 6.74 K/9, 3.26 BB/9 and an excellent 57.3 percent groundball rate. Now, if any team takes on the 27-year-old, it could get him for two seasons of arbitration control.
Lawson was the 71st pick in the 2016 draft who ranked as a top 100 prospect that year. He made his Double-A debut in 2019 and pitched to a 5.20 ERA/4.14 FIP with 11.71 K/9 and 4.23 BB/9 in 27 2/3 frames. MLB.com ranks him as the Padres’ 10th-best prospect and gives him a chance to at least turn into a stellar major league reliever.
Thompson is not among the Padres’ top 30 prospects at MLB.com, but the site is high on Marcano, whom it places at No. 8 in the team’s system. The 21-year-old middle infielder “could develop into a serious on-base threat as a bat-first middle infielder,” per MLB.com.
