Franklyn Kilomé was signed by the Phillies as an 18-year-old out of the Dominican Republic in January 2013, and his career as a professional baseball player began one year later. Skipping the Dominican Summer League, the right-handed pitcher made his professional debut for the GCL Phillies and had a solid showing for himself, posting a 3.12 ERA in 40.1 innings.
Over the next few years, he worked his way up the Philadelphia minor league system, making stops at Williamsport, Lakewood, Clearwater, and Reading. He began the 2018 with the Reading Fightin’ Phils, his second season playing for the Phillies’ Double-A affiliate.
