Seager led the Mariners with 25 home runs and 94 RBIs entering Thursday's game and earned his first American League All-Star berth this year. The 26-year-old has developed into an integral part of Seattle's young team since being drafted in the third round in 2009 out of North Carolina.
The Alumni Association selects winners from each of MLB's 30 teams, choosing players who demonstrate a passion for the game of baseball and best embody the values, spirit and tradition of the game.

Previous overall winners are David Eckstein (2005), Craig Biggio (2006, 2007), Grady Sizemore (2008), Albert Pujols (2009), Roy Halladay (2010), Torii Hunter (2011), Mike Trout (2012) and Dustin Pedroia (2013).
The final winner will be announced Nov. 18 at the 15th annual Legends for Youth Dinner in New York City.
The Seattle Chapter of the Baseball Writers' Association of America will also present its annual awards before Friday's game to the Mariners Player of the Year, Hitter of the Year and Unsung Hero.
The Mariners are closing out their regular season with three games at Safeco this weekend against the Angels. Friday is Fan Appreciation Night and Sunday will be Kids Appreciation Day, with prizes being awarded between each half-inning by random drawings.
