Go out and snatch up Pablo Sandoval at catcher if he's available, he also plays 3B and OF so you can put him at 3B and move Cantu to 1B to strengthen your lineup (if your league allows them to play those positions).
Looks like you didn't get to the outfield until the mid to later rounds... but OF is a dime a dozen position and you did a nice job. I also like you're infield up the middle with Rameriz and Phillips, I have the same combination on my team.
Also, your starting pitchers lack depth... See if you can scoop up Wandy Rodriguez, Umbaldo Jimenez, Gavin Floyd, Kyle Lohse, Jair Jurrjens, or even Chris Carpenter. Drop Duchenser and Sherzer if you can get any of these guys (some of them should be there in a 12 team league).
As far as relievers goes... Heath Bell flew under the radar in most drafts, He's got 2 saves already this year for San Diego and is available in a lot of leagues.
I'd give you a solid B+.
There's room to improve, but you've got some very nice pieces.
