LOS ANGELES (Hollywood Reporter) - CBS' new summer series "Rock Star: INXS" saw its fortunes improve in its second outing on Tuesday, but Fox appeared to take the night easily with its live coverage of Major League Baseball's annual All-Star Game.

The 10 p.m. airing of "Rock Star," in which contestants vie to fill the shoes of the Australian band's late vocalist Michael Hutchence, brought in 6.3 million viewers and 3.1 rating/8 share in the adults 18-49 demographic.

It improved on Monday's lackluster premiere numbers (5.5 million, 2.4/7), and did a respectable job of holding its 18-49 demo lead-in from 9 p.m.'s "Big Brother 6" (8.5 million, 3.4/10). However, NBC's repeat of "Law & Order: SVU" (8.8 million, 2.8/7) won the time slot in viewers.
