OKLAHOMA CITY, Oklahoma (Ticker) -- With star Ronny Turiaf battling injuries, J.P. Batista stepped into the spotlight for No. 23 Gonzaga.
Batista, a junior college transfer, scored a season-high 20 points on nearly perfect shooting and Adam Morrison added 19 as Gonzaga escaped with a 78-75 win over No. 3 Oklahoma State in the All-College Classic.
The upset was the second against a third-ranked team in the last 11 days for Gonzaga, which knocked off Georgia Tech, 85-73, in the Las Vegas Showdown on December 18. The Bulldogs, who shot 57 percent (31-of-54), improved to 2-1 against Top Five teams this season, losing to then-No. 1 Illinois, 89-72, on November 27.
Playing with a severely sprained left ankle suffered in practice on Christmas, Turiaf provided an early spark, scoring on his first two attempts - including a layup for a 14-10 lead with 16:02 remaining in the first half.
But the injury proved to be too painful for the Bulldogs' top scorer and rebounder, who collapsed to the floor after attempting a follow shot and limped off with less than nine minutes remaining in the half. He later returned in the second half and partially blocked John Lucas' 3-point attempt in the final seconds that would have tied the game.
Turiaf finished with 10 points on 4-of-8 shooting and grabbed six rebounds in 18 minutes.
Taking his place was Batista, who entered the contest averaging 6.9 points in his first eight games with Gonzaga (10-1). The Brazilian hit a jumper and made a layup within a 32-second span to give the Bulldogs a 33-28 advantage with 6:13 left in the half.
Batista added a layup five minutes later as Gonzaga grabbed a 48-39 halftime lead.
In the second, Batista continued his hot shooting, making his first three shots en route to a 65-55 lead with 10:58 remaining. Overall, he connected on his first nine attempts.
Despite trailing by as many as 16 points in the second half, Oklahoma State (9-1) clawed back to tie the score at 73-73 on a layup by Ivan McFarlin with 3:26 left.
Stephen Graham added a jumper almost two minutes later to knot the game at 75-75, but the Cowboys missed their final five shots to absorb their first loss.
Morrison shot 8-of-14 from the floor and Sean Mallon and Erroll Knight chipped in 11 points apiece for the Bulldogs, who posted their seven consecutive win. Derek Raivio added 11 assists.
Graham scored 22 points and Lucas added 19 for Oklahoma State, which uncharacteristically shot 39 percent (26-of-66) from the field. The Cowboys entered the game making 53 percent (267-of-508) of their attempts.
Joey Graham, Stephen's twin brother and the top scorer in the Big 12 Conference at 18.7 entering the game, had eight points on 1-of-6 shooting and grabbed nine rebounds.
Daniel Bobik, Oklahoma State's top 3-point threat, scored eight points but missed 6-of-8 attempts from the arc.
