Arizona’s Sweet 16 season began with a win against Charleston Southern and ended with a heartbreaking loss to Ohio State. In between, the Wildcats provided enough drama to fill the most fascinating page-turner. Here’s a look at Arizona’s 2012-13 season:

Nov. 11, 2012

The Wildcats open their season with a 82-73 win over Charleston Southern at McKale Center. Xavier transfer Mark Lyons scores a game-high 17 points in his Arizona debut.

The game between ranked teams — Arizona was ranked No. 7 nationally, Florida was No. 5 — coincided with an improbable win by the Wildcats’ football team. The UA scored two touchdowns in the final 46 seconds to beat Nevada 49-48 at the New Mexico Bowl.

Dec. 25, 2012

Johnson pins a shot from San Diego State’s Chase Tapley against the backboard, and Arizona holds on for a 68-67 win over the Aztecs in the Diamond Head Classic’s championship game. With the win, Arizona improves to 12-0 for the first time since the 1987-88 season.

Jan. 3

The Wildcats open Pac-12 play with a 92-83 overtime win over Colorado in McKale Center. The victory comes with some controversy as referees overturn what would have been a game-winning shot by CU’s Sabatino Chen at the end of regulation.

Oregon defeats Arizona 70-66 in Eugene, Ore., handing the Wildcats their first loss of the season. Lyons scores 21 points in a losing effort.

Jan. 19

Jan. 24

UCLA’s Shabazz Muhammad scores 23 points, sparking the Bruins to an 84-73 win over the Wildcats at McKale. The Wildcats miss 12 of their first 13 shots and twice trail by 16 points before rallying in the second half. The loss drops Arizona into a third-place tie in the Pac-12 race, two games behind Oregon.

Feb. 14

Colorado tops the UA 71-58 in Boulder, Colo., exacting revenge for its overtime loss in McKale Center earlier in the season. The Buffaloes lead by up to 15 points in the first half against No. 9 Arizona, which loses its second straight game. Spencer Dinwiddie leads all CU scorers with 21 points.

Feb. 23

Kevin Parrom scores a season-high 19 points as the Wildcats defeat Washington State 73-56 in McKale Center. The win is Arizona’s third in a row.

March 9

Arizona beats ASU 73-58 in McKale Center, earns No. 4 seed in the Pac-12 Tournament.

March 15

A late technical foul on UA coach Sean Miller helps UCLA edge Arizona 66-64 in a Pac-12 Tournament semifinal game. Miller says after the game that he was protesting a travel call against Lyons, claiming repeatedly that a UCLA player “touched the ball.” Miller is later fined $25,000 by the Pac-12 for confronting an official and “acting inappropriately” toward a conference staffer.

March 21

Because UCLA’s Jordan Adams broke his foot against UA, the NCAA tournament committee downgraded the Bruins and awarded the Wildcats the top tournament placement of Pac-12 teams –

a No. 6 seed and first game with Belmont in Salt Lake City. A trendy pick to get upset by normally hot-shooting Belmont, the Wildcats hold the Bruins to 38.6 percent shooting and win 81-64.

Lyons ties his career high of 27 points to lead the Wildcats to an easy 74-51 win over No. 14-seeded Harvard, which had upset No. 3 New Mexico.

March 28

A defensive switching error left Ohio State’s LaQuinton Ross open to hit a game-winning three pointer in the Buckeyes’ 73-70 Sweet 16 win at Los Angeles, ending the Wildcats’ season at 27-8.
