Beijing: Rafael Nadal slammed changes being mulled by tennis governing bodies to shorten matches and make them more TV-friendly, saying yesterday that the move goes against the sport's "values".

"The kind of matches that stay on (in) the memory and on the history of our sport are a little bit long and dramatic matches that become emotional," Nadal told reporters in Beijing.

Women's tennis boss Steve Simon said last week the WTA was considering introducing super tie-breakers and no-ad scoring for singles matches. The potential changes mirror the still-controversial rule shift made to non-Grand Slam doubles—on the men's and women's circuits—a decade ago. The new format would create shorter matches that are more predictable in length, making them easier for broadcasters to accommodate.
