The Silver Slugger Award is awarded annually to the best offensive player at each position in both the American League (AL) and the National League (NL), as determined by the coaches and managers of Major League Baseball (MLB). These voters consider several offensive categories in selecting the winners, including batting average, slugging percentage, and on-base percentage, in addition to "coaches' and managers' general impressions of a player's overall offensive value". Managers and coaches are not permitted to vote for players on their own team. The Silver Slugger was first awarded in 1980 and is given by Hillerich & Bradsby, the manufacturer of Louisville Slugger bats. The award is a bat-shaped trophy, 3 feet (91 cm) tall, engraved with the names of each of the winners from the league and plated with sterling silver. Designated hitters (DH) only receive a Silver Slugger Award in the American League because the batting order in the National League includes the pitcher; therefore, pitchers receive the National League award instead.
Three players are tied for the most Silver Slugger wins among designated hitters. Paul Molitor won the award four times with three different teams: the Milwaukee Brewers in 1987 and 1988; the Toronto Blue Jays in 1993, when the team won the World Series; and the Minnesota Twins in 1996. Edgar Martínez won the award four times with the Seattle Mariners (1995, 1997, 2001, 2003), and David Ortiz won four consecutively from 2004 to 2007. Don Baylor won the Silver Slugger three times in four years (1983, 1985–1986) as a designated hitter with the New York Yankees and the Boston Red Sox, and Frank Thomas won it twice with the Chicago White Sox (1991, 2000). Harold Baines won the award while playing for two separate teams in the same season; he was traded by the White Sox to the Texas Rangers in the middle of the 1989 season. Aubrey Huff is the most recent winner. Martínez set the records for the highest batting average and on-base percentage in a designated hitter's winning season with his .356 and .479 marks, respectively, in 1995. Manny Ramírez' slugging percentage of .647 is best among all winners at the position. Ortiz hit 54 home runs during the 2006 season, when he won his third consecutive award, and his 2005 total of 148 runs batted in is tied with Rafael Palmeiro's 1999 mark for best among designated hitters.
