3B - Pedro Alvarez
There are some nice late-round options at this position, and you're better off going with young guy than a banged-up veteran such as Chipper Jones. Alvarez is one of those options. He was labeled the top hitter of his draft class and he showed plenty of power in his first two-thirds of a season. His first full season could produce 25-plus homers and 100 RBI. David Freese is a close, close second as the Cardinals' likely everyday third baseman but his bat isn't as powerful.
Third basemen -- Jason Donald (CLE); David Freese (STL); Chris Johnson (HOU); Danny Valencia (MIN).
