He remained in Single-A in 2024, making 23 starts. Gough improved in nearly every area from his 2023 campaign, recording a 4.33 ERA through 95.2 innings and striking out 99 batters. He also had a 1.41 WHIP, which was far better than his mark from the season previous.
The Dodgers signed Ortiz as an international free agent in 2017, and he has remained in the system since. He pitched in rookie ball in 2017 and 2018, splitting time in the Dominican Summer League and Arizona League, before moving up to Single-A in 2019.

He had a 2.76 ERA with Oklahoma City through his 18 appearances, and the Dodgers ultimately moved him to the 40-man roster following the season. Following the move, though, the Dodgers have a free spot on the roster, and could look to add a free agent to fill the spot soon.
If not, though, the Dodgers received a younger pitcher who had a solid couple of seasons, and still has plenty of time to become a staple of the Dodgers' pitching staff.
