After presenting some of the last few '70s-born players to still have a Topps card in 2015, the question of who were the first '90s-born players to have a Topps card arises. So, just who were they? Considering only Topps base or Topps Update/Traded sets, I found the answer. The first of the '90s-born players appeared in the 2010 Topps Update set. Actually, there was only one--Starlin Castro.
