Biggest concern.. Fransico Cordero- He's blown two saves already, his WHIP, ERA are through the roof. Maybe last year was to much use. But he's my no.1 closer in 2 leagues.
Also, Mulder.. although his 2nd half last year somewhat had me worried to begin with and not expecting a whole heck of a lot of going into this year. I did however think he would rebound and be more like the pitcher of the 1st half of last year. So far not so good.
