Reds have four second base prospects that are very similar type players, all taken around the 3-5 rounds, all college players, similar physical builds. Between Valaika, Green, Lohman, and Wright, I have asked several scouts who have seen all four to compare the four. Universally, Green is thought to have the most upside because of his athleticism.
Reds are not exactly in the market for a second baseman, but you never have enough capable players from your farm system in the event of a need.
Puckett has also played a lot of second, but he is a totally different kind of player than these four.
Wright is on fire right now. Lets see how he progresses.
