Pretty sure everyone remembers McEnroe beating Borg in consecutive slams to send him into retirement.
That's why i said "usually". There are a few exceptions and the Borg/Mac is one of those few exceptions. But rarely how it works. To the earlier post, no one being honest could say they knew who each player ( Borg and Mac included)with more then a couple of GS's lost to or beat in each of their finals. You'd have to google it to know.
How many total slams they won, yeah most of know that or how many titles at a specific slam yes.
And by the way Mac and Borg( and YES i googled it) were tied 7-7 when Borg retired so met only 14 times.
