Root to Head, FOUR, there he goes. An Ashes 100 for South Australia's current favorite son on his homeground. He hugs Carey and then removes the helmet, ruffles his hair and goes on his knees to kiss the turf. His wife is elated. Gets there in style, comes down the track and lofts the tossed up delivery straight down the ground, clean hit and then the celebrations begin. The crowd just love it. They are cheering loudly. This is Head's fourth successive Test ton at Adelaide - two against West Indies, one against India and now this one. Certainly the most special of the lot. What a big match player he is, WTC final 100, Cricket ODI World Cup final 100 and now doing it in the Ashes, he is in some form. More on the celebration - Head had the bat in one hand and the helmet in the other as he raised them towards his wife and the crowd who lapped it all up. This hasn't been a typical Head hundred - he has batted out of character and dug in. Applied himself and gets the 100 he wanted on his homeground. A dream he would have had ever since he was a kid - an Ashes 100 and he gets it in front of nearly 50,000 adoring fans. A couple of fans wearing beige Travball tees are jumping up and down, they are thrilled
