Ronel Blanco
Early Life and Background
Ronel De Jesus Blanco was born on August 31, 1993, in the Dominican Republic, a country known for producing some of baseball’s most celebrated pitchers. Growing up surrounded by the sport, he played as a corner infielder and outfielder before eventually transitioning to the mound at the age of 18. The switch to pitching reshaped his career and gave him a clear professional direction. His development in the Dominican baseball system prepared him for the opportunity to sign with a Major League organization.
Standing out as a teenager with a strong arm, Blanco attracted the attention of scouts from the Houston Astros. The Astros signed him as an international free agent on April 27, 2016, when he was 22 years old, beginning a long path through the minor leagues. His early focus on building a versatile skill set allowed him to move through the Astros’ developmental ranks with consistency. That foundation would eventually carry him to the Major Leagues.
Path to Professional Baseball
Blanco began his professional career in the Dominican Summer League (DSL) and Gulf Coast League (GCL) during the 2016 season, going a combined 7–1 with a 2.13 ERA and 59 strikeouts over 50 and 2/3 innings. The following year, he split time between the Quad Cities River Bandits and the Buies Creek Astros, finishing 6–5 with a 3.38 ERA and 79 strikeouts across 88 innings. By 2018, his performance earned him a promotion to the Corpus Christi Hooks, where he combined with Buies Creek to post a 7–1 record with a 3.65 ERA.
In 2019, Blanco moved between three levels, including the Tri-City ValleyCats, Corpus Christi, and the Round Rock Express, finishing 5–2 with a 4.96 ERA. The 2020 minor league season was canceled because of the COVID-19 pandemic, and he spent 2021 with the Sugar Land Skeeters. These stops helped him refine his mechanics and prepare for his eventual promotion to the major league roster. His steady climb through the Astros’ system reflected both his work ethic and his growing command on the mound.
