In addition, right-handed reliever Eduardo Sanchez was selected to the first team for the South, but will not participate as he has since been promoted to the Double-A Springfield Cardinals.
Peterson, a 21-year-old left-handed hitter, was the Cardinals' second-round pick last June and earned mid-season All-Star recognition while with the New York-Penn League champion Batavia Muckdogs.
This season, Peterson has an impressive .307/.378/.443 line in the pitching-friendly FSL. He has four home runs and 30 RBI in 192 at-bats over 51 games. Peterson added nine stolen bases in ten attempts.
Freeman came on strongly last season, as he was promoted to Palm Beach at the end of the 2008 campaign and remained for the playoffs. The 21-year-old started with Johnson City after having been selected in the 32nd round of last June's draft.
His 2009 ERA is a sparkling 1.93 in 28 innings over 23 games. Freeman has fanned 24 but walked 11. Opposing hitters are managing just a .172 batting average against the former Kansas U hurler.
Sanchez, a 20-year-old from Venezuela, was moved up to Double-A on May 24. In 25 innings over 19 games with Palm Beach, Sanchez allowed just four runs for a 1.44 ERA. He fanned 26 and issued just five free passes.
Last year, the Cardinals had twice as many FSL All-Stars, six.
