ESPN's Keith Law updated his Top 25 prospects back on May 18th here, and since then, the following prospects have been called up to the majors:

Stephen Strasburg

Carlos Santana

Buster Posey 

Mike Stanton

So, who will be the #1 prospect come 2011? From Law's list, here are some of the players who are still in the minors who may contend:

Desmond Jennings

Martin Perez

Domonic Brown

Dustin Ackley

Jesus Montero

Jeremy Hellickson

Mike Trout

Mike Moustakas

Of the players listed above, Phillies outfielder Domonic Brown is probably having the best season to date, but Angels outfield prospect Mike Trout and Royals third base prospect Mike Moustakas may have something to say about that, with Trout doing so two levels below Brown and Moustakas.

A few guys not on his list that are having good seasons in the minors are Julio Teheran, and Arodys Vizcaino while Bryce Harper was the #1 pick in the 2010 draft. Could Harper be the #1 prospect in baseball in 2011?
