Cox went 3-for-3 with a solo home run and an additional run scored in Friday's 18-3 win over the Cubs.
Cox entered in the sixth inning and hit a leadoff single to right field before coming around to score, and he added another single later in the frame. The 24-year-old outfielder also opened the ninth inning with a solo home run to center field off catcher Carson Kelly. Cox has appeared in six straight outings since having his contract selected from Double-A Richmond on Sunday, batting 4-for-9 with three runs scored, a home run and a double in nine plate appearances.
