I just don't trust him. 10 blown saves, that is a TERRIBLE number. We should definitely start trying with different options by now.
First of all he has only 9 blown saves. Second he had a tough first six weeks as did the whole team when he started out 4 for 8 while dealing with his Grandmother dying, so let's give him a break for that.
Since then he is 29 for 34 which puts him in the top six in the league if you bother looking at the save totals for the league which I am guessing you have not. He is not great but good at closing. and has been for three years. Most of the time he has to save 1 run leads which is difficult. Most of the good closers are on good teams with 3 run leads in the ninth so giving up a run is not a big deal. Rarely does he give up more than run. His ERA is around 3 runs per game. Rauch gave up a run last night that killed us. His ERA is much higher than Cordero but rarely do people get on him.
