Perry Jones III had 19 points and 12 rebounds, and No. 4 Baylor made a season-high 15 3-pointers to stay undefeated with a 106-65 victory over Oklahoma State on Saturday.

Pierre Jackson scored 18 points and made five 3s for the Bears (17-0, 4-0 Big 12), who extended their school-record winning streak to 17 games. Freshman Quincy Miller had 21 points with three 3-pointers.

Baylor went into Saturday as one of three undefeated teams in major college basketball, along with No. 1 Syracuse and No. 15 Murray State. A big test comes Monday night when the Bears play at No. 10 Kansas.

The Bears scored their most points ever in a Big 12 game that didn't go to overtime. It was their most 3-pointers in a game since making 15 against Prairie View on Dec. 13, 2008, but still five short of the school record set in 1995.

Baylor was in complete control before halftime against the youthful Cowboys (9-8, 2-2). Oklahoma State's primary eight-man rotation includes five freshmen and only one senior.

Keiton Page, the lone senior, and sophomore Markel Brown had 15 points each for Oklahoma State.

The Bears already had eight 3-pointers by halftime, when they led 46-31. Jones then started the second half with a short baseline jumper.

Jones put the Bears up 61-41 with 13:52 left when he made a layup after an alley-oop pass from Miller was just mistimed.

But everything worked out perfectly on a highlight play in the first half. Jackson moved around a defender near the free throw line, but instead of taking the open shot threw an alley-oop pass to Jones for a monster dunk and a 33-23 lead.

Oklahoma State coach Travis Ford quickly called a timeout and was on the court almost before the play was done.

The Cowboys have dominated the series, including a 22-7 advantage since 1998. But Baylor has won the last six meetings in the Ferrell Center, including Saturday when they had a 48-25 rebounding advantage.

Quincy Acy had 14 points, six rebounds and two blocked shots for Baylor, which shot 53 percent overall (36 of 68) and 52 percent on 3-pointers (15 of 29).

Acy blocked a shot by LeBryan Nash with so much force midway through the second half that the ball wound up landing on the Oklahoma State bench. A couple of minutes later, Acy made a 3-pointer and walked away holding up three fingers toward his teammates.

Things were going so good for Baylor that Jackson made a 3-pointer late in the first half after the ball rolled around the rim a few times. When the ball finally dropped through the hoop for a 41-27 lead, the 5-foot-10 Jackson did a pirouette-like move near halfcourt.

Brady Heslip then stole the ball from Cezar Guerrero, who was still face-down on the court when Acy slammed the ball home.

Jackson made another 3-pointer from the top of the key in the final minute of the first half before Nash had a nice scoop shot for the Cowboys to end the half.

Baylor got off to a slow start, even though Miller hit a 3-pointer in the opening minute of the game. The Bears didn't score again until Heslip made a 3-pointer to tie the game at 6 with 16:36 left, and then went another 2 minutes before Jones hit a jumper that made it 8-6 and put them ahead to stay.
