How to maximize stud reliever

I'm fairly new at this and have read about how Dale Murray is such a dominant player. I have him now on a team but despite several tweaks I can't seem to get him in the game very often. He's only pitched 24 innings after 30+ games. Any tips on how to use him properly would be greatly appreciated.

I will never claim to be an expert, but I will relay some details from my last season. I picked up an r2/c1 reliever in the low 2 mil range that I had used before. I set him up as setup/tied and late/closer and he recorded a whopping 169.2 innings with a 1.04 whip and 2.12 era. he ended up with 20 saves. I used an f8 fatigue setting and he frequently had 2+ inning saves. I ended up cutting my 5 mil closer half way thru due to his lack of innings.
