With three test loses and two T20I loss, West Indies seem to have having their moment in the third T20. They had a spectacular start with both of the opening batsmen scoring not out half centuries and were already over 100 in 10 overs. If they kept the pace, they could easily go over 250. With more wickets in hand, they could play risky shots and score higher. T20 had been the favorite format for West Indies and I believe they'll have this win after a long drought of wins. Australia had been a strong team but anywhere near 250 would be extremely difficult to chase.
In the last T20I, we thought that West Indies might win, but our assumption was wrong because Australia, batting aggressively against a target of 215, defeated West Indies. Even if West Indies had scored 100 more runs with the way Tim David batted, Australia would have won today. However, in today's match, it was definitely felt that the pitch was entirely a batting pitch, due to which the bowlers bowled at a considerable cost in today's match, especially the West Indies bowlers who hit boundaries and overs whenever they bowled.
