Career .312 BABIP, last years .222. A groundball pitcher with mediocre stuff and a .222 BABIP is just variance. If there is anything to point to about last year it is that he finally had a league average LOB% which is something he has always struggled with the past, it might be due to the same variance as the BABIP though. Mitre didn't show improvement last year, he just had a little luck with his ERA which is more or less a worthless stat over 50 IP. I don't mind adding Mitre but you shouldn't put much if anything into last years ERA for him. As for Dickerson, no he isn't that great. He is however a marginal backup and that sounds good compared to Reed who probably isn't a major league backup quality player or Kotsay who shouldn't be on a roster.
