The 1990 Baltimore Orioles season was highlighted by the continued brilliance of Cal Ripken Jr., who earned an All-Star selection and showcased his ironman durability while leading the team in multiple offensive categories. Under manager Frank Robinson, the club remained competitive at Memorial Stadium and provided fans with memorable moments, including the long-anticipated and successful first major-league start of top prospect Ben McDonald, who tossed a dominant shutout in July. The season also saw strong individual performances from players like Randy Milligan and Billy Ripken, serving as a significant year of development as the franchise prepared for its upcoming move to Camden Yards.
