1. Ronan Kopp
Like Nastrini, Ronan Kopp is another exciting arm that Dodgers fans should be monitoring closely during the 2023 season. Kopp is already a big name for those who deeply follow the Dodgers farm system. But for the casual fan, Kopp might be a bit of a revelation.
Kopp is not your ordinary left-handed pitcher. The 2021 12th-round pick stands in at six-foot-seven and uses all of that frame to his advantage. Kopp has a really solid fastball that sits in the mid-to-high 90s with his tight slider being his best secondary pitch.
Those two pitches alone could get Kopp to the major leagues as a bullpen arm. Then again, he already has a four-pitch mix with a curveball and changeup. The more he develops those pitches, the more likely he has a chance to be a big-league starter.
Kopp thrived in 2022 in what was his first full minor league season. In 62.1 innings split between Low-A and High-A, he recorded a 2.74 ERA with 108 strikeouts. Like Nastrini, Kopp has similar struggles in his game. His command can be a bit iffy at times, and that led to a high walk rate over the course of the 2022 season.
If the Dodgers can limit the walks from Kopp and have him trust his stuff, then he's going to have a high ceiling as a pitching prospect. He's still only 20 years old and doesn't turn 21 until midway through the 2023 season. It might be some time until we see Kopp, but 2023 could be a breakout year that puts him on the map among the best left-handed pitching prospects in the sport.
