Palmer was the winning pitcher in 186 games in the 1970s, the most wins in that decade by any MLB pitcher. He also won at least twenty games in each of eight seasons and received three Cy Young Awards and four Gold Gloves during the decade. His 268 career victories are currently an Orioles record. A six-time American League All-Star, he was also one of the rare pitchers who never allowed a grand slam in any major league contest. Palmer appeared in the postseason eight times and was a vital member of three World Series Champions, six AL pennant winners and seven Eastern Division titleholders. He is the only pitcher in the history of the Fall Classic with a win in each of three decades. He was also the youngest to pitch a shutout in a World Series at age 20 in 1966. He was one of the starters on the last rotation to feature four 20-game winners in a single season in 1971. Palmer was inducted into the baseball Hall of Fame in 1990.
