What ia considered to be the minimum acceptable rate of Converting Saves for closers?

[philliesfiend55]

I wonder if a concrete number has ever been established for the minimum acceptable rate of converting Save Opportunities for closers.
I'm guessing about 85%. That's 34 Saves in 40 opportunities, with 6 Blown Saves. Am I close in this "Guesstimate" or is the cutoff point higher or lower?
To put it another way at what point is a closer likely to be replaced, traded or downgraded to a Set-Up Man? A 95 % rate would be very good, and probably put a player on an all-star team, but what rate is merely acceptable and at what point does a closer's Save Conversion rate become unacceptable?
Your opinions please. If anyone has actually done statistical research on this topic please share some of your results.

to know that we probably need to know the league average for successfull outings in save situations. anyone know it?

The league average was 70% this year. It looks like 80% to 85% is about as low as you want to be in order to keep a job as a closer.

RE: MLB average of 70% Success Rate in Save Opportunitie in 2012.
If a team has a 70% success rate in Save Opportunities then that probably results from the manager experimenting (out of neccessity) with a number of pitchers in the closer's role. I'm guessing that somewhere in the 80s percent range is an acceptable Save rate for one individual to remain a closer.
