Fixed.
I think I said this in other thread. In 2013 when he struggled a bit --2.92 ERA, 30 SV-- He said that he was not a fastball pitcher anymore. He said that he was working in his other pitches & command/control and those adjustments could take some time. It took 2013. Those adjustments made him even better since then.
2014 2.04 ERA, 91% SV%
2015 2.13 ERA, 92% SV%
Career 2.36 ERA 88% SV%
Not to mention that his durability is intact. As I said in 2011 when he signed with the Phillies, he is driving on Mo's Highway-- . LOL!
