According to MLB.com's Jonathan Mayo, Anthony Rizzo is the best first base prospect in baseball. In Mayo's top 10 prospects list, Rizzo ranks No. 1, interestingly ahead of Yonder Alonso -- who made Rizzo expendable in San Diego after the Padres acquired him as part of the Mat Latos trade.
In five minor league seasons between the Red Sox and Padres systems, the 22-year-old Rizzo owns an .880 OPS with 64 home runs.
Cubs 2011 second-round pick Dan Vogelbach made the list at No. 10. The 18-year-old, 250-pound Vogelbach appeared in six games for the rookie-level AZL Cubs, collecting seven hits and two walks in 27 plate appearances with a home run.
