Some good information Kimmi. I do have a couple of comments about some of this data. I think Porcello gave up more of his HRs to left-handed hitters because Comerica is shorter to RF and the park gives up more to HRs RF. Yes Fenway is longer to RF and this will help him against lefties, but Fenway is shorter to LF and gives up a ton of doubles. This will hurt him against right handed hitters, and there are more right handed hitters.
I am having a hard time recollecting a sinkerballer with a k rate as low as Porcello being successful at Fenway for an extended period.
IMO, Porcello will have to step up his k rate and keep the ball in the park to be successful at Fenway. He is not going to be able to continue hitting bats at the same rate as he has in his career and be a #2 for us. He has stepped up the k rate thus far, but he has had mixed results keeping the ball in the park.
