Thanks very much to Zero, a member of the Korean MLB message board, we now have translations. Here you go:
First panel (Featuring Adam Dunn, and Sean Casey):
Adam Dunn: Many strikeouts, many home runs.
Sean Casey: No strikeouts, many hits.
Coach: Casey + Dunn is better than BONDS!
Second panel (featuring Paul Wilson running away from Roger Clemons and Randy Johnson):
Basically just illustrates the Cy Young race from April to May, and Wilson pulling away early.
Third Panel (featuring Junior becoming injured):
Junior's box: Injury ... :(
Fourth Panel (featuring Ryan Freel):
Freel's box: Am I a regular player?
Manager's box: First choice Adrian Beltre, second choice Austin Kearns to third ... we have to make room for Wily!
Fifth Panel (Featuring Danny Graves):
Good? Not Good?
Danny Graves' box: I want to be good.
Manager's box: You are good ... where there are Reds.
(I think we're losing something in the translation on that one.)
Sixth Panel (Featuring Austin Kearns):
Austin's Box: Who are you?
Baby tied to him: I'm injury.
Seventh Panel (Featuring Cory Lidle):
Coach's box: Bad play and then you leave for the Phillies?
Cory's box: Sorry man!
So there you go, thanks again to our translator Zero from this message board.
