Hayden won more matches opening than Kane ever could at 3.
Here's a summary of all of Hayden's centuries in test:-
vs WI in Adelaide; 1997 (Home):-
AUS won the match by an innings and 183 runs; so, Bevan's all round performance (4/31, 85* & 6/82) actually won AUS the match, not Hayden's 125(226).
vs IND in Wankhede; 2001 (Away):-
Hayden's 119(172) was definitely important to take a 173 run lead in the 1st innings, but so was Gilchrist's 122 off 112 (even more so). Besides, Gilchrist too 6 catches in the match.
vs IND in Chennai; 2001 (away):-
Hayden did smash a double ton (203 off 320) in this match, but AUS couldn't win the match. Harbhajan's 15 wicket haul in the match (7/133 & 8/84) won IND the match by 2 wickets.
vs NZ in Brisbane; 2001 (home):-
Hayden scored a century (136 off 195), but so did Langer (104 off 231) and Gilchrist (118 off 158). Brett lee's all round performance (61, 5/67 & 1/53) won him the MOM award.
vs SA in Adelaide; 2001 (Home):-
Hayden scored a century (131 off 207) in the 2nd innings, which was definitely important to impose a massive 375 run target on SA. But there were two other centurions that match (Langer and Martyn). Warne's 41 off 77 in he 1st innings and 8 wicket haul in the match won him the MOM.
vs SA in Melbourne; 2001 (home):-
Hayden scored a century (138 off 211) in the 1st innings, which could be called a match winning knock, but it definitely wasn't a single handed effort. Langer scored 85(176), Steve Waugh scored 90(156) and Martyn scored 52(104).
vs SA in Sydney; 2001 (home):-
Hayden scored 105 & 21* in the match, But Langer scored 126 & 30* and Martyn scored 117(166). So, it was not a single handed effort either (Kirsten also scored 153(359) while following on).
vs SA in Johannesburg; 2002 (away):-
Hayden scored 122(189) in the 1st innings. But Martyn scored 133(207) and Gilchrist scored a double ton (204 off 213). Gilchrist was rightfully awarded the MOM.
vs PAK in Sharjah; 2002 (Neutral):-
Hayden's 119(255) in the 1st innings won him the MOM. But Shane Warne's very cheap (took those wickets at an average of 3) 8 wicket haul in the match (4/11 & 4/13) was very important to cause the PAK batting lineup to collapse.
vs ENG in Brisbane; 2002 (home):-
Hayden scored two tons in the match (197 off 268 and 103 off 152) and deservingly got the MOM award.
vs ENG in Melbourne; 2002 (home):-
Hayden scored 102 off 149, but Langer scored 250 off 407. So, it was Langer's innings that helped AUS to impose a follow on on ENG.
vs WI in Port of Spain; 2003 (away):-
Hayden scored an unbeaten century (100* off 180) in the 2nd innings. But Ponting scored 206(362), Lehmann scored 160(228) and Gilchrist scored 101(104); so, it was Ponting and Lehmann who took the 1st innings total to 576, Not Hayden.
vs WI in ST John's; 2003 (away):-
Hayden scored 177(260) but couldn't win the match.
vs ZIM in W.A.C.A; 2003 (Home):-
Hayden smashed a 380 off 437 and won the MOM, but it was against ZIM; so who cares?
vs ZIM in Sydney; 2003 (home):-
Hayden did score a quick hundred in the 2nd innings (101 off 85), which helped to chase down the total. But Ponting's 169 in the 1st innings and 53* in the second innings won him the MOM. Again, it was against ZIM; so, who cares?

Hayden scored 136(173) and 53*(63), but Ponting scored 257(458) in the 1st innings and was awarded the MOM.
vs SL in Galle; 2004 (away):-
Definitely a match winning performance from Hayden (41, 130 & 7 catches). But Warne got 10 wickets in the match. So, it wasn't a single handed effort either.
vs SL in Cairns; 2004 (home):-
Hayden scored two centuries in the match (117 off 184 and 132 off 169) and won the MOM, but Langer also scored 162(285); and the match was drawn.
vs ENG at The Oval; 2005 (away):-
Hayden scored a century in the first innings (138 off 303), but the match was drawn. The MOM was awarded to Pietersen for his 158(187). Warne's 12 wicket haul in the match is also worth a mention.
