Players in demand
1. Prince Fielder: He will play 2012 at age 28, so the team that signs him gets his peak years plus some early decline years instead of all decline. Fielder hits, hits for power, gets on base (even outside of the intentional walks) and has shown signs of improvement against left-handed pitchers. There are red flags, including his weight and below-average defense, but the potential for several years of high OBPs and 35-plus home runs make him top dog in this market.
