Robert Anthony Grich is an American former professional baseball player. He played in Major League Baseball (MLB) as a second baseman for the Baltimore Orioles (1970–1976) and the California Angels (1977–1986). In 1981, Grich led the American League in home runs and won a Silver Slugger Award. A six-time All-Star, he also excelled as a defensive player, winning four consecutive Gold Glove Awards between 1973 and 1976.

In baseball and softball, second baseman, abbreviated 2B, is a fielding position in the infield, between second and first base. The second baseman often possesses quick hands and feet, needs the ability to get rid of the ball quickly, and must be able to make the pivot on a double play. In addition, second basemen are usually right-handed; only four left-handed throwing players have ever played second base in Major League Baseball since 1950. In the numbering system used to record defensive plays, the second baseman is assigned the number 4.
