Ten prospects/rookies on the rise

When my initial Top 100 fantasy prospects for 2012 was published on March 1, it was missing one key element: spring training games. Games are played, injuries happen, young players impress … so here are 10 rookies who have seen their fantasy stock jump since early March.

Matt Carpenter, IF/OF, Cardinals

Carpenter seemed bound for a repeat performance at Triple-A entering the spring, but he earned an Opening Day roster spot not only by hitting .357/.438/.661 in exhibition play but also by showing some position versatility, playing both infield and outfield corners. With starters at those positions who include David Freese, Lance Berkman and Carlos Beltran, there should be plenty of at-bats available for Carpenter, and you know what he does? [Snap!] He gets on base.
