I thought it might be kind of interesting to throw up some images of front pages from Nikkan Sports and Sponichi. The other main papers (like Daily Sports and Sanspo) also feature images of their front pages, but don't offer an archive. If I happen to remember to check them on a daily basis, I'll try to add them into the mix as well.
I will only focus on "interesting" baseball-specific front pages for the time being.
In any case, here they are:
Nikkan Sports 2/8
In serious pitching mode: Ichiro hits 147km/h
Nikkan Sports 2/9
Darvish, Angry! "This isn't baseball!"
Darvish, victim number 1 "This isn't baseball!"
Nikkan Sports 2/13
Uehara heating up! 150 tosses from the start!
