G.O.A.T.
I could bring up Borg's comebacks but I'll start with these and for the record early round is before R16.
USO 2006 Safin vs. Nalbandian 2R
6-3, 7-5, 2-6, 3-6, 7-6(6)
WMB 1999 Courier vs. Schalken 3R
7-6(2), 3-6, 3-6, 7-5, 13-11
(Trivia, Courier would have another 5 set epic with Henman losing 7-9 which turned out to be his last match on grass)
French 1992 Sanchez vs. Masur 2R
3-6, 5-7, 6-3, 6-4, 13-11
AO 2002 Koubek vs. Saulnier 1R
0-6, 1-6, 7-6(6), 6-4, 8-6
(Koubek would go on to make the quarters beating James Blake in the following round also down 0-2 before straight set win and tight 4 set against Fernando Gonzalez)
The Koubek Aussie run is special for a player to start a Slam tournament with back to back 0-2 comebacks and as an unseeded player to face 2 qualifiers in the first 4 rounds.
