When Manny Machado arrived at Camden Yards amid much fanfare, Orioles manager Buck Showalter insisted the 20-year-old player was promoted for no other reason than to help the team win. And that is precisely what Machado did in his second game in the major leagues. Machado thrust himself into the Orioles' record book by hitting two home runs and driving in four runs, a power display that carried Baltimore past the Kansas City Royals 7-1 on Friday night.
