Area scout Tom Kunis and scouting advisor Paul Cogan saw de Geus hit 92 mph at Cabrillo (Calif.) JC and liked his makeup and the way his arm worked, so the Dodgers signed him for $75,000 as a 33rd-rounder in 2017. His post-Draft physical revealed a heart condition that delayed his pro debut until 2018, when he got pounded for a 7.26 ERA in Rookie ball. He was a different pitcher in 2019, reaching Class A Advanced and finishing with 28 strikeouts in 23 consecutive shutout innings that included eight scoreless appearances in the Arizona Fall League.
Los Angeles' player development staff helped de Geus upgrade his pitches but it may be the Rangers who benefit because they grabbed him in the Rule 5 Draft at the end of 2020. After topping out at 95 mph with a straight fastball in 2018, he now deals a 93-98 mph heater with running action. He also has improved his breaking pitches and now operates with a low-80s curveball with power and depth and an upper-80s slider/cutter.
De Geus' confidence improved along with his stuff, and he did a much better job of attacking hitters last season, when his walk rate dropped to 1.9 per nine innings from 3.9 in his debut. His ability to generate strikeouts and weak ground-ball contact could make him a late-inning relief weapon. Texas will have to keep him on its active big league roster throughout 2021, or else expose him to waivers and offer him back to the Dodgers for half of his $100,000 draft price.
