Wood bowled swiftly and well with the new ball, notably making life hard for David Warner, and leaving open the tantalising question of what a difference he might have made to England's Ashes tilt.
Bayliss, however, deserves credit for what he has achieved, with England's one-day side unrecognisable from the ragtag outfit that so disappointed at the 2015 World Cup in Australasia. What a wicket. It was a bit wide with a hint of turn.
The biggest question, of course, remains the same - how do you get out Steve Smith, although with the white ball this time as opposed to the red.
0930 hrs IST: 50 up for Australia in the 10th over. Moeen missed a half-chance for a return catch off Finch, who was also at the centre of proceedings when England lost their lone review - Rashid pushing hastily for an lbw referral to a wrong'un comfortably sliding past leg stump.
Finch's innings ensured Australia had a decent platform from which to launch in the closing overs.
0850 hrs IST: Okay, here we go!
He had gone on to 60 when he scooped a delivery from Chris Woakes to Joe Root at mid-off, ending his 80-run partnership with Tim Paine (27) and costing Australia late innings momentum.
He put on 118 with Finch for the fourth wicket after Australia were in a little trouble at 78 for three following the dismissal of Travis Head for five. A lovely drive from Finch through mid-on to get four!
A third MCG century against England for Aaron Finch and a recast middle order allowed Australia to climb to 8 for 304 after being sent in to bat and made to hop around early on by a fast and hostile Mark Wood in the opening ODI.
Australia have liberally employed stand-in coaches for some limited overs assignments themselves using them as an opportunity to trial the best coaches in the country while giving Darren Lehmann a break. This match is Jos Buttler's 100th for England, and he was presented with a commemorative cap by James Anderson before play. They have been brilliant in the 50-over games in the recent past and a win here would be so good for them.
