The Masters Tournament was watched in 13 percent fewer households in the biggest U.S. markets than a year ago, according to preliminary information, as South Africa’s Charl Schwartzel captured the title and a final-round rally by Tiger Woods stalled on the final nine holes. Yesterday’s fourth round at Augusta National Golf Club was watched on CBS in an average of 10.4 percent of households in the top 56 U.S. television markets, compared with last year’s 12.0 equivalent rating, CBS Corp. (CBS) said in a news release. This year’s ratings were the second-highest for the final round in the last decade, up 18 percent from 2009 and up 1 percent from 2005, when Woods won the last of his four green jackets as champion, according to Bloomberg.
