ARLINGTON, Texas — Adolis García hit two drastically different solo homers, Corey Seager also went deep and newly acquired left-hander Jordan Montgomery worked into the seventh inning to help the Texas Rangers beat the Miami Marlins 6-2 on Friday night. García put the Rangers ahead to stay when he went the opposite way with a high-arching 334-foot homer just inside the right-field pole for a 3-2 lead in the third.
