I mean...he's not terrible. The last three years he has pitched to a 2.58 ERA. The only thing that scares me is his 1.323 WHIP over that span. Over the last three years, Ayala has a LOB% of 85.7, 80.7, and 80.9, respectively. The average is supposed to be 72%, according to Bradley Woodrum on Youtube (http://www.youtube.com/watch?v=ggFArD4tffk
). His ERA will eventually rise due to the fact that more base-runners should start scoring. Again, I'm not in any rush to sign him, as he's practically an average reliever in market where average relievers are not hard to acquire.
