Clay's worst night IMO, mostly due to the songs rather than his voice. First he forgets the words to song 1 (crappy song anyway), sounded great on #2 but that song is just way too lounge-cheesy, and on song 3 the arrangement was completely terrible (way too fast), he sounded good but I still didn't like it.
Also, Ruben is starting to sound kind of hoarse. It doesn't matter, though, Kim will almost certainly go. She's a good singer, but not as good as the other two and she's not much of a performer IMO.
