The San Francisco Giants are currently the toast of Major League Baseball.  Featuring the best rotation in baseball and coming off a World Series championship, the Giants look to become the first team since the 1999-2000 New York Yankees to win consecutive World Series.

A crucial contributor to the 2010 San Francisco Giants was NL Rookie of the Year Buster Posey, a can’t-miss prospect who made good on his potential with the Giants by becoming one of the team’s leaders both on and off the field.

In 2011, the Giants have another such player in Brandon Belt, a five-tool first baseman (how often do we say that?) who ripped up the minor leagues in his first season of pro ball and is looking to make the Giants out of spring camp.

Belt will not be the only impact rookie in the majors this season, though.  

Here we take a look at 30 rookies looking to make an impact at the major league level in 2011.
