There's an owner in Rickey who uses this guy: Yonder Mercedes
as his closer. His numbers are sick.
I've had similar DUR/STA guys get 90-100 ip, but as you can see this guy logs about half of that.
When asked about it, the owner stands firm that when Mercedes pitches he is lights out, so he'd rather have him closing games, and that losing the 50 innings per season is irrelevant because "all innings are not the same".
