Two of the Mariners' first-round selections, Alex Rodriguez and Griffey, are members of the 500 home run club. Rodriguez won a World Series title with the New York Yankees, four Hank Aaron Awards, three American League MVP awards, and was named to 13 All-Star teams. The Mariners have held the first overall pick four times, most recently in 1993. The Mariners have made eight selections in the supplemental round of the draft and 11 compensatory picks over their history. These additional picks are provided when a team loses a particularly valuable free agent in the previous off-season, or, more recently, if a team fails to sign a draft pick from the previous year. The Mariners have failed to sign two of their picks, Scott Burrell in 1989 and John Mayberry, Jr. in 2002. For failing to sign these picks, the team received the 38th pick in the 1990 draft and the 37th pick in the 2003 draft, respectively.
