1990s: 1995 Upper Deck Traded #459 Jamie Navarro The righty had probably the best year of his career in 1995. The Cubs picked him up as a free agent before the season and were hoping for a mid-rotation innings eater. They ended up with an ace-for-the-season. He went 14-6 with an ERA of 3.28.
2000s: 2007 Opening Day #179 Scott Moore Moore was less. He spent the first half of the season in AAA, played in a few July games for the Cubs, and then was traded to the Orioles in late August.
2010s: 2011 Topps Traded #115 Kerry Wood The prodigal returns! Kerry Wood came back to the Cubs as a free agent for the 2011 season. The deal got its start as Wood and GM Jim Hendry spoke at Ron Santo's funeral in December. I never noticed this on the card before, but if you look down the line at the other player's hats, one of them is wearing a Ron Santo 10 hat.
