The third annual MLSsoccer.com 24 Under 24 — the ultimate ranking of the top young players in MLS — will return on September 10, with the #1 player being revealed on Friday, September 21. This year, we're letting you have your say in who that #1 player should be.

Beginning Monday, August 20, fans will have five days to complete the ballot, helping MLSsoccer.com to select the top players under 24 from clubs around MLS. Those votes will count for 10 percent of a player's ranking with the other 90 percent determined by the submissions of an expert media panel, including the editorial staff of MLSsoccer.com.

Brek Shea's monster 2011 season for FC Dallas put him in pole position and he ran away with the No. 1 ranking last year, following in the footsteps of Seattle's Fredy Montero, who was selected as the top Under-24 player in the inaugural 2010 edition.

Shea and 18 of the other 2011 finalists are once again in the running this year, part of 182 eligible players listed below. To be eligible, players have to be 23 years old or younger as of the end of the 2012 regular season on October 28, 2012.

Fans can get a head start and compile their cheat sheets ahead the opening of the polls on Monday.
