Alvin Davis (born September 9, 1960 in Riverside, California) is a former Major League Baseball first baseman/designated hitter who played for the Seattle Mariners and California Angels. He batted left-handed and threw right-handed. Davis broke into the Majors with the Mariners in 1984 and remained there until 1992 when he played one season for the Angels before retiring. He has been considered to be the first true superstar to play for the Mariners. A winner of the Rookie of the Year Award, he also was selected an All-Star in his season debut.
Davis was a career .280 hitter with 160 home runs and 683 RBI in 1206 games. He hit 20-plus homers in three seasons and drove in over 100 runs in two.
Though Davis' statistics are by no means mind-blowing, he was well known within the Mariners organization and held just about every offensive team record for quite a few years. He won his team's MVP award in 1984, 1988 and 1989.
Davis was inducted into the Seattle Mariners Hall of Fame in 1997.
