First of all, the very main characters are Abe-kun, catcher and Mihashi, pitcher.
The whole team from Nishiura High!
Sorry, i couldn't get very nice wallpapers. So, these pictures are in average sizes only.And i just started watching...i'm not very familiar with the characters except for a few like the team captain, Hanai-he's the one in bandana(towel) on the far left in the last pic, cleanup hitter(also their ace), Tajima(he is very cute)-the one on the far left in second pic i think and both the main charaters.
And i like the opening songs from this anime too.
First opening - Dramatic by Base Ball Bear
Second opening - Seishun Line by Ikimono Gakari
