CBS’ “The Amazing Race” crossed the finish line with a flourish on Wednesday, ranking as the night’s top program among the youngest of adults.

According to Nielsen, “Race” won each half-hour in adults 18-34, growing from a 4.1/13 at 9 to a 5.3/16 at 10:30. In the broader categories of total viewers (11.25 million) and adults 18-49 (5.2/14), “Amazing Race” placed a solid second to NBC’s combo of “West Wing” and “Law & Order.”

It especially seemed to take a bite out of “Law,” which fell to its lowest rating for a regularly skedded firstrun episode (6.2/16 in 18-49) since February 2000, although it still dominated its hour in overall aud (18.30m).

For the night, CBS finished just 2 shares behind first-place NBC in adults 18-49. Other than nights featuring “Survivor” or music specials, in fact, the Eye delivered its strongest Wednesday 18-49 rating (4.2/12) since mini “Jesus” wrapped in May 2000.

This was the second edition of “Race,” with a third on tap for the fall.
