NORMAN, Okla. (AP) -- Oklahoma coach Sherri Coale didn't have much time to remind the Sooners what happened the last time they played Missouri. Turns out, she didn't need to.
Nyeshia Stevenson and Ashley Paris each scored 14 points as No. 2 Oklahoma extended its winning streak to 14 games and remained atop the Big 12 Conference by routing the Tigers 78-56 on Saturday.
Oklahoma (18-2, 7-0) avenged its last loss to a Big 12 foe while sending Missouri (10-10, 1-6) to its fourth straight defeat. The 12th-seeded Tigers stunned NCAA tournament-bound Oklahoma 70-64 in overtime in the first round of last season's conference tournament.
That memory helped keep the Sooners focused in what appeared to be a classic trap game, sandwiched between a win Wednesday at No. 4 Baylor and a marquee nonconference matchup on Monday in Oklahoma City against No. 13 Tennessee and coach Pat Summitt, who will be seeking her 1,000th victory with the Lady Vols.
``You go play at Baylor, you get back, you've got your mandatory day off and you've got one day to prepare for this one,'' Coale said. ``There just wasn't time to talk about much of anything. But I think our guys remembered what happened in the Big 12 tournament last year and they weren't going to let this one slip away.''
Alyssa Hollins led Missouri with 17 points while Shakara Jones had 11, but the Tigers shot just 32.9 percent from the field, compared to 50 percent for Oklahoma. Both teams had five 3-pointers, but Missouri's came on 24 attempts, while the Sooners took 14 shots from behind the arc.
Oklahoma center Courtney Paris had 10 points and 11 rebounds in 21 minutes of playing time to extend her NCAA-record streak of consecutive double-doubles to 112 games.
Missouri coach Cindy Stein said this season's Oklahoma team is far ahead of where the Sooners were when the Tigers scored their upset, citing the development of Ashley Paris and an improved perimeter game.
``I just think that the key factor for Oklahoma has been Ashley Paris ... being as good as she is,'' Stein said. ``Whitney Hand being able to score on the perimeter, as she does, the way Danielle Robinson can get to the basket and Amanda Thompson is doing a terrific job of scoring.
``Last year, we were not worried about their perimeter scoring and we would just try and pack it in and now you can't do that. They're all playing really well together. They are a terrific team and we knew it.''
Oklahoma led all the way, although the Tigers kept it close in the early minutes and were within 24-14 after RaeShara Brown's put-back with 8:54 left in the first half.
A 3-pointer by Amanda Hanneman pulled Missouri to 30-20 with 6:25 left, but the Tigers didn't score the rest of the half. Oklahoma started pouring it on with a run featuring a 3-pointer by Hand, which she put up even as Courtney Paris stood at half-court with her arms upraised in a ``good'' sign.
Robinson added a basket moments later to give Oklahoma a 45-20 halftime lead.
A 10-2 run to start the second half by Missouri cut the gap to 47-30 with 18:19 left, but the Tigers didn't score again for more than six minutes. Oklahoma scored 15 straight points in the interim, including seven from Stevenson, who came off the bench and reached double figures for the third time in Big 12 play.
``I'm as confident as I've ever been,'' Stevenson said.
Courtney Paris secured her double-double on a bucket with 6:53 left - which gave Oklahoma its biggest lead at 71-38 - then exited the game 24 seconds later. Ashley Paris narrowly missed her own double-double, finishing with nine rebounds.
``I thought we did some really good things in the first half,'' Coale said. ``We looked a little sluggish in the second half, perhaps as if our mind was somewhere else already and it shouldn't have been. But any win you get in the Big 12 is a good one.''
Hand and Robinson each scored 10 points for Oklahoma.
``They've got all the weapons,'' Hollins said of the Sooners. ``It's hard. There's nobody you could sit off of.''
The Sooners have won 10 of their last 12 games against Missouri, although the Tigers still lead the series 29-25.
