Fuentes has been stellar in the closer's role though.
Yes doctor, I am sick. Sick of those who are spineless. Sick of those who feel self-entitled. Sick of those who are hypocrites. Yes doctor, an army is forming. Yes doctor, there will be a war. Yes doctor, there will be blood.....
Anything with Tsao at this point would be a gamble:
a) Fuentes could continue to excell and secure the job coming into camp next season, regardless of competition;
b) Tsao could come back at full strength and convince the Rox to shift Fuentes back to the LH setup role;
c) Tsao could come back at full strength but be stuck in setup anyway;
d) The Rox could ship Fuentes (highly unlikely, though many teams are after him) and Tsao could once again be the default option for '06;
e) Tsao might not be at full effectiveness when next season starts, regardless of other closing options.
I might hang onto him in a dynasty or very deep keeper, but I wouldn't go chasing him if it cost a useful roster spot.
