Fox's coverage of the NCLS Game 1 averaged 7.7 million baseball fans through 11 pm.

9 pm
CSI returned to an audience of 22.99 mil, down seven percent from its previous opener, and bested Grey's Anatomy in the 18-49 demo for the first time ever. Grey's dropped 20 percent from its premiere, with 14.54 mil. The Office did a typical nine mil, then SNL's new Thursday showcase built the audience to 10.6 mil. (Yeah, that’s the ticket!) Supernatural slid 430 thou, to 3.14 mil.

10 pm
It was neck-and-neck for dueling newbies Life on Mars (11.6 million) and Eleventh Hour (11.59 mil), though ABC came out on top in the demos.
