Grey's Anatomy continued to dominate in the 18-49 demo Thursday night, leading ABC to its third-straight Thursday night victory, according to overnight estimates.

CBS' CSI scored 14.6 million to Grey's 13.8 million, but the ABC drama handily defeated the CBS procedural among adults 18-49. The Office's buzzed-about, hourlong wedding episode also outperformed CSI in the demo and pulled in 9.1 million viewers for the show's best numbers in nearly a year. Fringe and Supernatural held steady at 6 million viewers and 2.5 million viewers, respectively.

Survivor: Samoa won the 8/7c timeslot with 11.7 million viewers. FlashForward dipped a bit to 9 million viewers, while Bones improved to 9.9 million. NBC's Community (5.1 million viewers) improved over last week's SNL: Weekend Update Thursday, but the show lost 13 percent of the audience it was pulling in when it followed The Office.

Parks and Recreation built on Community's audience, pulling in a season high of 5 million viewers. Vampire Diaries maintained 3.5 million viewers.

At 10/9c, The Mentalist was watched by 14.2 million viewers. Private Practice won the demo but came in second in overall viewers (9.5 million), followed by The Jay Leno Show (4.8 million viewers.)

Ratings for almost every show were down due to cable coverage of the Major League Baseball playoffs.
