Is this a good trade for me?

if you need pitching then do it. id say if you have an average pitching staff or better then dont do it. Hanson is a young gun with ace potential. Tulowitzki is barely behind hanley for the best SS in the MLB. Bailey and Jimenez are good young pitchers also. but normally you would want better hitters than pitchers. so unless you need the extra pitching help theres no need to do it.
