Joe Mauer for Russel Martin?

Hey Y'all, I'm in an 8-Man League (ESPN) which is judged on R,HR,RBI,SB,AVG,K,W,SV,ERA, WHIP. I'm currently sitting in 2nd place (46-32-2) I feel my pitching is very strong, but my lineup isn't. I have the lowest AVG and RBI total and would like to boost those up. Just wanted to know what ya'll think about these trades. Thanks a lot guys, much appreciated.
