Scouting grades: Fastball: 50 | Curveball: 50 | Slider: 55 | Changeup: 50 | Control: 45 | Overall: 45
Known as Leandro Calderon when he signed for $10,000 in 2021, Lopez spent his first two pro seasons at home in the Rookie-level Dominican Summer League and missed most of 2024 with shoulder fatigue. He improved his conditioning afterward, which led to a breakout 2025 season that earned him a spot on the 40-man roster. He compiled a 2.40 ERA, .198 opponent average and 111 strikeouts in 101 1/3 innings between High-A and Double-A.
Lopez can create quality depth on two different breaking balls, and his upper-80s slider supplanted his low-80s curveball as his best pitch last year. His fastball operates at 93-95 mph and touches out at 97, albeit with more downhill plane than life and a tendency to catch the heart of the plate too often. He's still learning to locate his mid-80s changeup where he wants but it misses bats with tumble when it's on.
Getting in better shape allowed Lopez to repeat his delivery, provide consistent strikes and maintain his stuff better than he had previously. His upright delivery and high arm slot help him stay on top of his breaking pitches but detract from his fastball shape. Upgrading his heater and continuing to refine his control would help enhance his chances of becoming a big league starter.
Scouting grades: Fastball: 50 | Curveball: 55 | Slider: 60 | Changeup: 40 | Control: 45 | Overall: 40
Known as Leandro Calderon when he signed for $10,000 out of the Dominican Republic in 2021, Lopez spent two years in the Rookie-level Dominican Summer League before coming to the United States in 2023. After losing much of last season to shoulder fatigue, he returned in the Arizona Fall League. Improved conditioning and control and heavier reliance on his slider have helped him become one of the top starters in the system this year.
Though Lopez's low-80s curveball ranks as one of the best among Rangers farmhands, he has leaned more into his upper-80s slider with depth, which has turned into a plus pitch in 2025. His fastball sits at 93-95 mph and touches 97 but catches the heart of the plate too often. He lacks faith in a mid-80s changeup that tumbles at its best.
Getting in better shape has helped Lopez do a better job of repeating his delivery and providing consistent strikes for the first time as a pro. He works from a high arm slot that helps him stay on top of his pitches but produces less fastball life. If he can continue to refine his control, he can make it as a big league starter.
