TUCSON, Ariz. -- Mark Lyons had an Arizona career-high 25 points and Solomon Hill added 23 as the seventh-ranked Wildcats overcame a 10-point, first-half deficit en route to a 73-66 Pac-12 victory over Stanford at McKale Center on Wednesday.
Lyons dropped a pass into forward Angelo Chol for a layup that gave the Wildcats a 56-54 lead with 4:26 remaining, then made a layup and a 3-pointer on the next two possessions to key a spurt in which Arizona outscored Stanford 24-12 over the final 5 1/2 minutes.
Arizona (20-2, 8-2 Pac-12) earned a seventh straight win in the series and took a half-game lead in the Pac-12. No. 19 Oregon, also 7-2 entering the second half of league play, plays host to Colorado on Thursday.
Center Dwight Powell led Stanford (14-9, 5-5) with 24 points. Cardinal point guard Aaron Bright had 16 points, making four of six 3-pointers.
Lyons, a senior transfer from Xavier, shot 9-for-13 from the field. He scored his career high, 27, with the Musketeers.
Kevin Parrom's jumper on a feed from Lyons gave Arizona a 65-59 lead, and after Powell made two free throws, Hill made a driving, left-handed dunk and two free throws for a 69-61 Arizona lead.
Chasson Randle's 3-pointer with 36 seconds left made it 69-64, but Parrom sank three free throws add Hill made one down the stretch as Arizona pulled away.
Arizona took a 49-47 lead when Chol hit a layup with 7:43 remaining, but Randle hit a 3-pointter on the next possession and Powell made two free throws to put the Cardinal up 52-49.
Stanford, which had won five of its last seven games after an 0-2 conference start, scored the first 10 points of the game. Bright made a layup and two 3-point field goals in the first 3 1/2 minutes while Arizona missed its first five shots and committed two turnovers.
Chol, who had played only 25 minutes and scored three points in the first nine conference games, cut the Wildcats' deficit to 14-12 on a tip-in with 11:34 left in the first half. However, Bright and John Gage hit back-to-back 3-pointers from the top of the key as Stanford extended its least to six. Bright had 11 first-half points.
Arizona trailed just 27-26 at the break following Jordin Mayes' steal and fast-break layup with 50 seconds left in the half.
