The Australia vice-captain earned the man-of-the-match award for a notable all-round performance which helped Australia to a 66-run win under the Duckworth-Lewis Method and handed them a 2-0 lead in the five-match series.
Clarke hit a vital 56 from 98 balls to help Australia recover from a shaky start and reach 213 for five from their allocation of 50 overs, and then snared three wickets for 26 runs from six overs, as West Indies failed to successfully chase a revised target of 204 off 41 overs.
"I think the pitch is probably one of the worst that I have played on in international cricket," he said.
"It seamed early, and a few balls went through the top, and once the ball got older, it was really slow and it was hard to score runs.
"When Mike Hussey and I were batting together, we thought that if Australia could get between 220 and 240, it would be a decent total for us to defend. Unfortunately, we fell just a little bit short."
Clarke added exactly 100 for the fourth wicket with Hussey to help lift Australia to a respectable total, and he disclosed that the pitch at times made them laugh at themselves.
"We felt disgraceful out there," he said. "At one stage he said to me, 'Mate, I feel as though I can't hit more than a single', and I had to tell him, I knew what he meant.
"But the end result was that we put on 100 runs, and we are obviously happy that we got through that tough period, and get that partnership for the team, but certainly it felt like a scrap. We hung in there, and we did not get out.
"I thought the pitch would be low and slow, but I didn't think it would seam the way it did early on.
"There was a little bit of rain overnight, and a little bit of extra moisture at the start, but it seamed for more than 30 overs, and I think all the batters on both teams found it difficult to score runs, and as soon as you tried to take too many risks, you found yourself in the dressing room watching."
Clarke asserted that Australia's will be to win Sunday's third ODI which would give them a chance of sweeping the series.
"Our game plan is to win every game we play, and this would be to hopefully leave West Indies winning 5-0 in this ODI series," he said.
"It obviously is going to be an important match because we know that if we win on Sunday, we essentially have won the series."
The last two ODIs of the series will be contested on July 4 and 6 at Warner Park in the St. Kitts capital of Basseterre.
