It was Nigel Lythgoe night on Fox on Wednesday with back-to-back competition shows produced by the former choreographer. Almost to the finish line, it was the season’s last performance night for American Idol (2.9/10). Finalists Candice Glover and Kree Harrison sang three songs each on the one-hour live show from LA’s Nokia Theatre. The most-watched show of the night with 11.57 million viewers, Idol was even with the final numbers of last week’s two-hour show but up 12% in the 8-9 PM hour. As is common with live shows, those results could be adjusted in the final numbers later today. Tonight’s finale will see a few surprises aside from declaring a winner, including performances of new tunes from judges Mariah Carey — with Randy Jackson on bass — and Keith Urban.

The second night of the two-part premiere of Season 10 of So You Think You Can Dance (2.3/6) headed to Detroit for the first time for the next round of auditions, with Season 4’s tWitch joining the judges panel, SYTYCD benefited from its Idol lead-in with a 21% jump over Tuesday’s premiere. It also saw viewership leap 39% to 7.11 million. On a night that saw the NBA Playoffs on TNT, Fox was tops in both viewers and adults 18-49 among the broadcast networks.

Earlier in the night, CBS had two 2 Broke Girls encores at 8 PM (1.0/3) and 8:30 PM (1.1./4) followed by an original Criminal Minds (2.5/7) that was even with last week’s show. The CW had the season finales of Arrow (0.9/3) and Supernatural (0.9/3).
