Each of Major League Baseball's 30 teams have a nominee. The last two years, Boston's nominee -- Tim Wakefield in 2010 and David Ortiz last season -- won the award.
After overcoming cancer in 2006, Lester has given a lot of his time to various charitable endeavors.
His newly-formed NVRQT ("Never Quit") initiative launched with the pediatric cancer research foundation this year, on the five-year anniversary of Lester being declared cancer-free.
Voting is under way through Oct. 14 at MLB.com/ClementeAward as fans help decide which of those 30 club winners will receive this prestigious recognition. The nominees were chosen based on their dedication to giving back to the community, as well as their outstanding ability on the field.
Fans who participate in the vote will be automatically registered for a chance to win a trip to the 2012 World Series.
