LOS ANGELES (AP) — T.J. McConnell scored 13 of his 17 points in the second half, freshman Stanley Johnson added 12 points, and second-seeded Arizona made a dominant late rally for its 14th straight victory.
Kaleb Tarczewski had 12 points and 12 rebounds as the second-seeded Wildcats (34-3) weathered a major scare from the sixth-seeded Musketeers (23-14) and clamped down defensively during a game-ending 19-7 run.
With its third Elite Eight berth in five years, Arizona gets another shot at its first Final Four under coach Sean Miller, who led Xavier for five years until 2009.
The Wildcats will face top-seeded Wisconsin (34-3) on Saturday at Staples Center in a rematch of last season's West final won by Wisconsin in overtime.

Trey Lyles scored 14 points, Andrew Harrison added 13 and the unbeaten Wildcats, chasing history and a ninth national title, rolled into the Elite Eight.
Kentucky (37-0) advanced to Saturday's regional final to play third-seeded Notre Dame.
With stunning ease, the Wildcats built a 26-point lead in the first half over the Mountaineers (25-10), who led the nation in steals and figured their full-court press would at least bother Kentucky into some turnovers. West Virginia shot only 24.1 per cent (13 of 54), including 2 of 15 from 3-point range.
West Virginia didn't eclipse 20 points until the 11:41 mark of the second half.

Notre Dame will play top-ranked and unbeaten Kentucky on Saturday night with a Final Four spot on the line.
Fred VanVleet led Wichita State with 25 points, Darius Carter had 19 points and eight rebounds but guard Ron Baker had just nine points and went scoreless in the second half.
