LINCOLN, Nebraska (Ticker) -- Victor Williams rescued Oklahoma State from another disastrous shooting performance.
Williams scored 20 of his season-high 25 points in the second half as the 14th-ranked Cowboys posted a 77-70 Big 12 Conference victory over Nebraska.
Three days after shooting a woeful 34 percent in a non-conference loss at Cincinnati, Oklahoma State (19-3, 8-1 Big 12), got off to a slow start in the first half, but trailed just 30-25 at halftime.
The Cowboys came in shooting 46 percent in league play, but in their last two league games against Kansas State and Texas, they combined to shoot 40 percent (45-of-113).
During its 15-game winning streak, Oklahoma State shot at least 50 percent seven times and never shot below 35 percent.
In the second half, the Cowboys' second-leading scorer got going. Williams sank three jumpers in a span of 85 seconds that gave Oklahoma State a 56-52 edge with 7:25 remaining.
Williams later added a 3-pointer with 5:25 to play that extended the Cowboys' lead to 62-55.
Williams' three baskets gave Oklahoma State the lead for good and sparked a decisive 17-8 run that made 69-58 with 1:43 remaining.
Brian Conklin's 3-pointer was Nebraska's only basket during the run. It brought the Cornhuskers within 56-55 at the 6:20 mark.
But Jason Miller converted a three-point play, Williams sank his 3-pointer and reserve Cheyne Gadson added another basket before Williams ended the spurt with another jumper with just under two minutes remaining.
Williams shot 7-of-11 in the second half as Oklahoma State shot 61 percent (17-of-28) over the final 20 minutes and 47 percent (27-of-58) overall.
The Cowboys also bounced back from a poor 3-point shooting display in the opening 20 minutes. They shot just 2-of-12 from beyond the arc in the first half, but 5-of-7 in the second.
As the Cowboys struggled on offense, their defense kept the game tight early. They held the Cornhuskers to just 35 percent (11-of-31) in the first half and never trailed by more than five points.
Nebraska shot just 38 percent (22-of-58) overall and it marked the 10th time an opponent failed to shoot 40 percent against Oklahoma State.
Nebraska (9-13, 1-8) lost its sixth straight and was led by Brennon Clemons, who scored a season-high 21 points.
Ivan McFarlin added 17 points and Melvin Sanders chipped in 16 for Oklahoma State, which moved into a tie with Kansas for first place in the Big 12.
