In a live league you'll be fine... in a regular league, Sparky's decisions are a little rough on a big inning long reliever, so you'd get somewhere around 90-100 appearances and around 250 IP out of him. Don't use him in the first game, and I'd even recommend skipping the 2nd if you can as well.
As for the closer question brought up above, unchecking the "only use in save situations" box only allows the closer to be brought into tie games as well. I always leave that unchecked, even for my 40IP closers as I'd rather they come in in a 9th inning tie than my mop up. The only way to get more innings out of a closer is to set their availability to earlier innings such as the 7th or 8th. In that case you can push them to close to 100 IP, otherwise, I don't see you ever getting more than about 75 IP out of a closer only available in the 8th or 9th and in only save situations.
