Dec 2020 Report
Evaluator: Matt Thompson
Age: 21 yr
Height: 6-2
Weight: 185 lbs
Hits/Throws: S/R
Acquired: 2016 IFA
RuleV: On 40-Man
Physical Description: High waisted athlete, with a still developing frame. Plays smaller than his 6'2" frame, but hope is he adds some strength and develops some power to go with some already strong all-around skills. Noticeably different frame from earlier in the season and his time at AFL. I'd bet he added 10-12 pounds of muscle to the frame.
Hit: Perdomo is a very skilled craftsman in the box, and if you watch him play everytime you will see something new in his setup or approach. Very loose in the box, hands always swaying, body rocking back and forth, staying loose. He starts from a wide base, with his front foot pointed inwards. For his trigger he barely lifts his front foot off the ground, but does bring it backwards as his load before striding forward a few inches from where he was originally. His hands are his best asset, and his bat-to-ball skills are very strong. It's a swing geared for contact, and he will make plenty of it. Contact percentages around the 85% mark in 2019. He finishes high, with that one armed whip like finish, with the bat pointing straight up in the air. He's a switch-hitter and is a much better hitter from the left-side. His right-handed swing is more of a slap hitters approach, and very flat. Perdomo has an innate feel for the strike zone and is constantly in three ball counts and making the opposing pitcher work. Can't tell you how many times I saw Perdomo go down looking on bad calls by the home plate umpire. His eye was simply too advanced for Low-A, and better than most umpires down there. If you factor the walk rate in with the hit tool it's an easy plus tool. Grade: 60
Power: Perdomo has bottom of the scale power from the right-side of the plate, but as a left-handed hitter he's starting to show flashes of a developing skill that can change the profile. He's never going to ever be a big power source, but he's going to have to be able to drive the ball. His average exit velocity at Kane County was around 81 MPH, but within a year he was up to 87 MPH in the AFL. The body has filled out some over the course of the season, and he was at the plate looking to do damage, as opposed to just looking to get on base like he had been earlier in the year. He had a sturdier base out in Arizona, was putting more of his weight on his back leg, looking to drive the ball. While in Low-A he would take a pitch and immediately follow it with a series of steps in the box. His weight was on his front foot. We're seeing a shift in philosophy taking place here and his 2020 season happened mostly behind closed doors, with limited eyes on him. That being said, I see Perdomo topping out around 10-12 homers per season, which if the rest of his game translates to the big league level, that's more than enough. Grade: 40
Field: Smooth hands, good actions and internal clock at short. Perdomo is a natural at shortstop and is the organization's shortstop of the future. He makes the flashy play look routine, and sometimes makes the routine play a little flashy, but it's all part of the package. The Diamondbacks had him playing some second base at Kane County in an effort to add versatility, which they've been doing with all of their prospects in the minors. He's a shortstop going forward though. He's quick and his long strides allow to him to cover plenty of ground. Moves to his left particularly well and has strong footwork Grade: 60
Arm: An above-average throwing arm that allows him to get more than enough on throws from the hole or shallow centerfield to first. It's an accurate arm as well, but will sail the occasional throw. Grade: 55
Run: Plus runner with long strides, Perdomo is a pest on the bases. Pitchers treat him as such as he routinely draws 3-4 pickoff throws per time on base, and is very aggressive with his leads. His caught stealing numbers can be a bit misleading as a large percentage of his outs on the bases were him getting picked off rather than thrown out by the catcher. So his stolen base success rate is much higher than it looks on paper. It is troubling that he gets picked off so frequently, but he pushes the limit with strong leads and I've witnessed him trip or stumble multiple times trying to get back to the first base bag. He also doesn't get out of the box very smoothly and I've seen him stumble a few times there as well. Body control is something he could work to improve. He's a plus runner though and should be able to steal 15-20 bases in the big leagues. Grade: 60
Overall: There's a high floor here due to the defensive value and borderline elite plate skills, but also some upside with the emerging power. I've seen Perdomo play in probably 40+ games and have a strong feel for what he can do on the field, and while I'm skeptical of his long term power output, there is no questioning the rest of his game.
