NEW YORK -- The British Open's final-round overnight TV ratings dropped 4 percent from last year.

ABC Sports' telecast of Ben Curtis' stunning victory drew a 4.7 rating, down from the 4.9 when Ernie Els won a four-way playoff in 2002.

The rating is the percentage of all homes with TVs, whether or not they are in use. Overnight ratings measure the 55 largest TV markets in the United States, covering nearly 70 percent of the country.

Each overnight rating point represents about 735,000 TV homes.
