Looks like Porcello has finally figured out that he needs to get back to relying on his sinker.
From WEEI:
"His sinker was working well, which has been a main reason for his success over the last two starts.
'I’m basically forcing myself to throw it. That was kind of the commitment after I came off the DL — I’m going to throw my sinker and find it,” Porcello said. “If I get beat with that pitch, then so what? In order for me to have some success over here in the long run, I’ve got to find that pitch. I just took the pressure off and said, ‘Screw it, I’m throwing it.'”
