Should I trade r. Baldelli and c guillen for c. utley and j valverde?

f. cordero and b. Jenks are my closers. I did pick up j. accordo today to replace bj ryan (possibly). In my leagure we start 4 rps, but holds are a category. carlos lee, j. bay, c. patterson and victorino are on my team for of as well. I have H. ramirez and weeks, so utley would be my utility. What do you think? Should I do this?
