In 1990, Ripken had perhaps his most successful campaign offensively. The Orioles' second baseman with the exception of a stretch in August in which he was hurt, he batted .291, the highest total of his career and a mark which would lead the Orioles in 1990. He also tied with his brother for the team lead in doubles (28) Defensively, Ripken finished fifth among AL second basemen with a .987 fielding percentage and led AL hitters with 17 sacrifice hits. Billy and Cal committed a total of 11 errors, the fewest in major league history among second baseman-shortstop combinations that appeared in at least two-thirds of their team's games at their respective positions.
