Neither is expected to play Sunday night in Frisco, but Gallo has officially been added to the roster. Gonzalez could make his first start as early as Tuesday.
Gallo, a 20-year-old third baseman, leads the Minor Leagues in home runs with 21 and is batting .323 with 50 RBIs. Gonzalez, a pitcher, was the Rangers' top pick in the 2013 First-Year Player Draft. In Myrtle Beach, he went 5-2 in 11 starts with a 2.62 ERA.
So that Gallo could be added to the roster immediately, Chris Grayson was moved down to Myrtle Beach.
