Wondering which young players could have an impact in the majors this year? Let MLB FanHouse guide the way in Better Know a Prospect. In this edition we look at three players from the underrated Cincinnati system.Chris Valaika, SS: The biggest knock on him is that he doesn't have great plate discipline. Valaika hit .306 in the minors, but he's never drawn more than 35 walks in a season, so if he can't keep hitting for a high average it will be tough for him to be valuable. On the flip side, he has the defensive chops to stick at short and good pop for a middle infielder. Considering incumbent shortstop Alex Gonzalez struggled to stay healthy last year and you can make the same criticisms of his game, Valaika could get a shot at the major league level sometime this year.
