After going through the Reds Media Guide, I found every player who was signed last year (as a free agent, not including draft picks) or this year who will be making their debut in 2008. There are 21 players total and they are listed below.
Personally, seeing kids born in 1991 in the system is mind boggling to me, but I guess I am getting older. I doubt that many of them see time in the United States, but it will be interesting to follow those that do closely while checking in on those down in the Latin Leagues when they start.
Fourteen of the twenty one guys were signed out of the Dominican Republic, with two from Italy, two from Venezuela, one from Germany, Canada and one from Netherlands. Almost half (10 of 21) of the players signed were pitchers while the rest were split between catchers, shortstops and outfielders.
