A native of Gilbert, Arizona , Watson pitched at Perry High School. Despite being drafted in the later rounds of the 2015 draft, he elected to sign for a $400,000 bonus, well above the slot value.  After posting a ERA as a starter across two levels in 2016 ( Class A Short Season , with the Auburn Doubledays , and Class A Full Season , with the Hagerstown Suns ), Watson was labeled by Baseball America and Minor League Ball as a prospect to watch in the Nationals farm system.   In 2017, Watson was selected among several Hagerstown players to participate in the South Atlantic League All-Star Game. 
Perez was an international signing by the Astros out of the Dominican Republic in 2014. Perez pitched with the DSL Astros and Greeneville in 2015 posting a ERA with 50 K in 55 IP. Perez had a semi-breakout 2016. He started the season with Tri-City and had a ERA with 12 BB/36 K in IP. He was promoted to Quad Cities where he struck out 44 in IP, though he walked 22. Perez possesses a mid-90s fastball and a very good slider. He also has a curveball, though the slider is his best secondary pitch. His control still needs work but he is just 20 years old and has a good pitcher’s build at 6’3″ and 190 lbs.
