In all fairness, the old Yankee Stadium wasn't really a hitters park overall (outside of the short porch down the RF line, the dimensions weren't really hitter friendly). For most of Bernie's career the park factors rated it as slightly a pitchers' park.
For a switch hitter like Bernie the porch comes into play. I think the average SH hits lefty about 65% of the time at least.
