Australian skipper Ricky Ponting has been fined 30 percent of his match fee for dissent during Friday's second one-dayer win over hosts West Indies.
An International Cricket Council (ICC) statement said Ponting appeared to make a comment to the umpire after he had turned down a caught-behind appeal against Patrick Browne.
Although Ponting pleaded not guilty at the post-match hearing, ICC match referee Roshan Mahanama punished the player after viewing video footage of the incident.
Australia won the rain-hit game in Grenada by 63 runs, taking a 2-0 lead in the five-match series.
