In 2016, considering fly balls and line drives hit to right field, at Yankee Stadium there were 115 home runs hit in 502 such PAs, for a HR% of 22.9%
Ignoring Bonds, there were 15 HR in 587 at AT%T in 2001 = 2.6%. so if you hit a line drive or fly ball to RF, you were about 10 (!) times as likely to homer at Yankee in 2016 as at AT&T in 2001 (if you're not Barry Bonds).
In 2001, Bonds hit 33 line drives or fly balls to right field at AT&T resulting in 17 homers. Considering he only hit 33 such balls that year, there's a hard cap at an additional 16 homers, and he obviously wouldnt have homered in all those extra chances (and he wouldnt have homered 170 times in 33 PA obv), but he probably would have hit another 5 or 10.
