One of the best young pitchers in the game, yet an already proven ace and Cy Young award winner, Clayton Kershaw is surely a no-brainer candidate for collecting.
I love his stuff and am trying to collect his cards, particularly his autos.
Not that he has a nice, ornated autograph, like say Dennis Eckersley:

This is from this year Topps Tribute, a really nice set where signatures really stand up.
Then I have this really nice 2007 Bowman Sterling, numbered to 199, with jersey:

He was a prospect, not yet in the Majors, a card that will gain value as his career progresses.
Then, I have this 2009 Topps ticket to stardom, also with jersey, numbered to 489:

With all this prospects, futures and stuff I still don’t have a proper rookie card autograph of Clayton, and if you excuse me, I think I’m out now to fill the gap.
