Base Set Calling trade received - getting younger

I received these four 2013 Topps Update Chrome cards from Brian at Base Set Calling - in exchange for 2013 Topps Update Chrome cards of Brian Wilson, Jake Peavy, Mariano Rivera and Oswaldo Arcia.

It was a fairly straightforward trade - I traded three cards of veteran players and one rookie in exchange for rookies of four guys [though I probably have several other cards of each player already].

The cards I received adds some 'card depth' in case there are opportunities at some ballpark - where I can get at least a couple of cards signed in-person when the particular players' teams come to town.
