As the competition tightens in this season of FOX's "American Idol," the show's judges are running out of things to say about Murray teenager David Archuleta.

Having wowed the judges from the early going, Archuleta drew the standard chorus of "good performance," "beautiful voice" and "smart choice of song" from judges Randy Jackson, Paula Abdul and Simon Cowell. Many media observers and bloggers predict he will be in the show's final round.

During weekly results shows, contestants are eliminated by popular vote among the show's viewers. Though the vote totals are not announced, Archuleta has never been among the bottom three vote-getters. Wednesday, Archuleta was the second contestant to be declared safe from elimination. Brook White, a 24-year-old nanny originally from Mesa, Ariz., was eliminated Wednesday. There are now four contestants left, including Archuleta.

This week, "American Idol" contestants were asked to sing two of Neil Diamond's songs. Archuleta chose to sing "Sweet Caroline" and "America." Diamond was on hand to coach the contestants and offer comments about them.

"He's kind of a prodigy," Diamond said of Archuleta on Tuesday's show, "and with a little guidance and a couple of suggestions, which I hope he takes to heart, I think he'll do great on the night of his performance."

Archuleta and the remaining contestants will perform again Tuesday at 7 p.m. on FOX, channel 13.
