The Adelaide Oval was a picture on Friday for day one of the first-ever day night test match.

History was made at the Adelaide Oval on Friday and few would have believed who the Australians called in to be part of it.

In the gripping opening day, massage therapist Grant Baldwin made headlines when he ran onto the field as a sub-fielder for Australia in the historic day-night test match.

Skipper Steve Smith made the call to use the support staff member ahead of the designated sub-fielders from South Australian Cricket.

In his prime 28-year-old Baldwin was a talented sportsman in his own right. He was an able second XI cricketer for Victoria and was once registered for the AFL draft.

But he left his playing days behind to help get the team into physical working order and travel the world with the Australian side. He also does some logistics work to assist team manager Gavin Dovey.

Smith backed Baldwin, who had his own green cap, to handle the historic occasion in front of more than 44,000 people, even though he hadn't played for the Victorian Seconds since February 2008.

Getting amongst the team preparation on the field is nothing new for Baldwin, he often runs fielding drills at training and has previously fielded in tour games in South Africa and the UAE. Baldwin even bowled an over in South Africa last year during a tour match.

But to field in a test match is another level altogether, especially one as significant as the first ever day-night test match in front of an audience of millions.

It was a remarkable decision from Smith and one the Aussies will surely have laughed about on Friday night after they dominated day one.
