I am adding to the answer because the information supplied by the responder has some noteworthy information on the NY Yankees. That answer can be seen in the last two paragraphs.
The best New York Yankee lifetime winning percentage by a starting picther is held by Lefty Gomez. He pitched in the 1930's and had a winning percentage of .839.
