In a remarkable irony given his injury history, vice-captain Shane Watson would lead the side in Clarke's absence less than a week after returning from another lay-off. Clarke battled with hamstring problems during the last two Tests against Sri Lanka in Melbourne and Sydney and missed the opening two one-day matches of the summer. "He asked to have his right hamstring assessed by team medical staff," a Cricket Australia spokesman said after the match. While the injury is not considered serious Australia already leads the series 4-0 and Clarke leaves for India on Monday with the final group of 17 players in the touring squad. The first Test begins at Chennai inside two weeks. For the second time in three days since his return from injury Watson set the foundation for an Australian victory. A stunning rearguard century from all-rounder Kieron Pollard failed to save the West Indies as Australia won by five wickets wickets with 5.1 overs to spare. A Big Bash favourite with the Adelaide Strikers, Pollard made 109 not out in 136 balls with 11 fours and two sixes yesterday, dragging his side from 6-55 to 220 in 49.4 overs. Watson followed his run-a-ball hundred in Canberra last Wednesday by top-scoring with 76 from 84 balls last night in front of yet another modest one-day crowd of 18,161. The innings was yet more evidence that Watson's best place is at the top of the order in all forms of the game, putting further pressure on Ed Cowan to hold his place as an opening batsman in India following a disappointing Test series against Sri Lanka. Watson broke down with a recurring calf strain during the Boxing Day Test in Melbourne but has stepped strongly back into international cricket. His innings was nowhere near as comfortable as the 122 he made from 111 balls in perfect batting conditions at Manuka Oval earlier in the week. He should have been caught behind on 32 but wicket-keeper Devon Thomas dropped a straight-forward chance. Watson should also have been run out by metres when 51 in a mix-up with another modest runner between wickets, Phil Hughes, but was saved when bowler Narsingh Deonarine knocked a bail off with his arm as he took the ball. Facing the fastest bowler on the night, Tino Best, Watson touched a lifting delivery to be caught behind. It appeared the West Indies would struggle to make three figures midway through their innings but Pollard managed to turn his series and his team's fortunes around. He received good lower order support from captain Darren Sammy (25 in a partnership of 43), Andre Russel (18 in a 35-run partnership) and Sunil Narine (23 in a 64-run partnership). It looked a very different game when Mitchell Johnson ripped through West Indies top order, claiming 3-11 in his opening four overs as the West Indies slumped to 3-17.
