New Zealand captain isn't anxious about not having enough game time going into World Cup and said that the IPL as well as a few practice matches back home have kept the side in good stead.
"Australia have always had strong squads", Root said.
"It gives you confidence knowing you have scored runs over here in the past", he said.
"It was very scary", said Shaun Marsh after the game.
With Smith and Warner back, Marsh is not certain of a place in the side for the World Cup opener against Afghanistan in Bristol on June 1 but he thought his versatility might work in his favour. "It looks like a lot of the work that Justin and the senior players have done around the group is starting to pay off".
Both men played key parts in the recently concluded edition of the Indian Premier League (IPL) for their respective franchises, though they had to leave the tournament early due to the Australia camp. Steve Smith still thinks he's not probably 100 per cent fit just yet - but he's not far away.
"Those two coming in, obviously they're class players - they'll have their fair share of issues to deal with from the crowds and stuff when they get over there", he said. But they're big boys. "I'm sure they'll be fine". Lo and behold, after playing dreadfully in one-day internationals since 2015, they have won their past eight games, clinching a 3-2 series victory in India and then whitewashing Pakistan in the United Arab Emirates, even without Smith and Warner.
Yet, with the top six gelling superbly without them in recent times, the rehabilitated pair now seem more of a bonus than a prerequisite for a team looking to win their fifth World Cup in six tournaments and sixth overall.
Smith scored 76 off 82 balls as Australia scored 230 for three to beat West Indies by seven wickets in a match so low-key that the ICC deemed it a practice session rather than a World Cup warm-up. It is worth mentioning that Smith (Steven Smith) and Warner Warner were banned for one year in a ball-tampering case.
The Windies then lost three quick wickets for 30, when Zampa bowled Andre Russell for five before Glenn Maxwell (2/14) trapped Evin Lewis LBW (50) and then tempted Nicolas Pooran with a short delivery and Marsh took the catch on the boundary.
"And I think some of our middle order are probably slightly better players of spin now than they were 12 or 18 months ago".
The left-handed batsman and spin bowler Moeen Ali said, "We all make mistakes, we are human and we have feelings, I know deeply that they are really good people".
