Porcello has made 4 starts against the Yankees this year.
One was a 2 IP, 0ER outing at the end of the season that is worth ignoring.
He did get pasted onece for 5 ER in 5.1 IP. That was his only real start i Yankee Stadium.
his other 2 starts at Fenway were spectacular outings - 16 IP, 1ER - including a complete game one hitter. If he pitches like that, the crowd might be out of the game quickly...
