Crawford, a career .293 hitter, is among the top 15 outfield candidates to receive votes. The left fielder, who was the Rays' 2004 All-Star selection, has led the American League in triples and stolen bases three times each.
Upton is currently in fifth place among second basemen, down one spot from last week, behind New York's Robinson Cano, Detroit's Placido Polanco, Texas' Ian Kinsler and Boston's Dustin Pedroia.
The 22-year-old leads the Rays in batting average among those with at least 100 at-bats, and likewise led the American League for a time in May. He's second only to Crawford in team steals.
