Victor Martinez, an All-Star with the Red Sox in 2010 and now a catcher/designated hitter in Detroit, is among five American League players on the list. Fans can vote until 4 p.m. Thursday. The winners will be announced on MLB.com.
Martinez is joined on the list by Baltimore outfielder Adam Jones, Chicago first baseman Paul Konerko, Kansas City outfielder Alex Gordon and Tampa Bay infielder/outfielder Ben Zobrist.
Yankees outfielder Nick Swisher edged Boston's Kevin Youkilis in the Final Vote last year.
