According to MLB insider Robert Murray, the headliner heading to Washington is shortstop Gavin Fien, one of the Rangers’ most highly regarded prospects. Right-hander Alejandro Rosario is also part of the package, along with first baseman/outfielder Abimelec Ortiz, infielder Devin Fitz-Gerald, and outfielder Yeremy Cabrera, completing the five-player return to the Nationals.
