No. 7 Garrett Cooper
While being around league average with both the Marlins and Padres after being traded, he is a filler first baseman. He's around league average if not below league average defensively; he is more of a hitter. While not fitting the mold of a "Moneyball" player, he can hit around .260-.280 a season with around 10 home runs, if he stays healthy and plays a full season.
His asking price is low as he hasn't played too much. Now 32, turning 33 by the start of next season, he's more of a player you can count on, unlike some of the players on this list, and with one of the lowest values on the list too, I would snag him up.
