Trade Advice for Saves based on Roster

[boydkpacker]

Hello Fantasy Baseball Wizards,

Right now I'm in third place (out of 12) in yahoo Ros. Scoring with R, HR, RBI, SB, TB, AVG, W, SV, K, TB, ERA, WHIP.

I know I need better pitching--someone in the league is interested in trading Rivera for something good. What should I offer?

M. Barrett, R. Sexson, J. Kent (1B, 2B) , D. Wright, J. Reyes, A. Soriano (2B,OF), V. Guerrero, A. Dunn (1B, OF), C. Tracy (1B,3B,OF), J. Vidro, A. Rowand

Pitchers: J. Vazquez, J. Smoltz, B. Jenks, C. Cordero, C. Lee, J. Contreras, J. Bonderman, B. Myers, J. Lieber, J. Westbrook

Also, roster slots are daily with positions
C, 1B, 2B, 3B, SS, OF, OF, OF, Util, SP, SP, RP, RP, P, P, P, BN, BN, BN, BN, BN, DL

Thanks for your thoughts.
