The Honus Bonus Partners Cards released this year have milestone 1/1s for players recounting homeruns, wins, saves, etc.
I had 2 already, but when the opportunity presented itself to add this new 1/1 to my collection for only $5 I couldn't pass it up. I have since added one more as well. I can't begin to fathom trying to collect them all.
Commemorating Cutch's 44th career Home Run off Jonathan Sanchez in a 9-2 victory on August 10, 2011. Cutch batted leadoff in the game and went 1 for 1 with 3 walks. He also scored 4 times, drove in 3, and stole 2 bases. That's a heck of a day.
