Texas Rangers rookie Josh Jung is already setting personal milestones for himself. On Sunday, the slugging third baseman may have completed his most impressive feat yet, hitting the first grand slam of his young career. In the bottom of the first inning, Jung launched a ball 368 feet to give his team an early 4-0 lead. The 25-year-old is the first Rangers third baseman to hit a grand slam since Adrián Beltré hit one on August 15th, 2016. Jung is also just the 16th rookie in franchise history to hit one.
