Pitcher Jonathan Hernandez was signed by the Texas Rangers on January 30, 2013. He was born in Memphis, TN, but as the son of Fernando Hernandez, who pitched briefly in the majors, his first few years were spent as his dad moved around the minor leagues, before the family settled back in the Dominican Republic. His first two professional seasons, in 2013 and 2014, were spent in the Dominican Summer League where he was 3-1, 1.21 for the DSL Rangers the first year and 5-2, 2.85 for the DSL Rangers 1 the second. He was obviously among the most talented young pitchers in the organization, but since he was just 16 the first year, the Rangers did not want to rush him to the United States too soon.
He did move to the U.S. in 2015, when he pitched with the AZL Rangers. In 11 games, he was 1-1, 3.00 then in 2016 he was assigned to the Hickory Crawdads of the South Atlantic League, playing full-season ball for the first time. He went 10-9, 4.56, pitching 116 1/3 innings. In 2017, he started the year back with Hickory, going 2-5, 4.86 in his first 9 starts before earning a promotion to the Down East Wood Ducks of the Carolina League. While his numbers may not have been superficially impressive, the combination of his young age and excellent stuff got him named to the World Team for the 2017 Futures Game, representing the D.R. He finished the year with a combined record of 5-11, 4.03 in 23 games, with 111 2/3 innings pitched and 110 strikeouts. In 2018, he started off very strong for the Wood Ducks, with a record of 4-2, 2.20 in his first 10 starts to earn a first opportunity in AA, with the Frisco Rough Riders of the Texas League. While he found the going tougher there, he still finished the season at 8-6, 3.63 with 134 strikeouts in 121 1/3 innings, maintaining his status as one of the organization's top pitching prospects.
