COLLEGE PARK, Md. (AP) - Senior Stephanie Jones scored 18 points, sophomore Shakira Austin had 17 points and 13 rebounds, and No. 7 Maryland stayed atop the Big Ten by pounding Purdue 88-45 Tuesday night in College Park for its 13th consecutive victory. 

The Terrapins (24-4, 15-2) are tied in first place with Northwestern, which kept pace with a victory at Ohio State. The co-leaders have one game left: Maryland is at Minnesota and Northwestern hosts Illinois.

If the Wildcats and Terps finish deadlocked, they share the title but Maryland gets the top seed in the Big Ten Tournament via a tiebreaker. Northwestern and the Terrapins split the season series, so the next criteria is head-to-head record against third-place Iowa (Maryland went 1-1, Northwestern 0-1).

Senior Kaila Charles had 14 points and 11 rebounds for the Terrapins, who haven't lost since Jan. 9 at Iowa. Their last five victories have come by an average of 34.4 points. Fellow senior Sara Vujacic added 10 points. Freshman Diamond Miller added 12 points off the bench. 

Maryland dominated the inside against the Boilermakers, scoring 60 points in the paint and shooting a blistering 49.4% percent from the floor. The Terps also finished with a 49-34 rebounding advantage.

Ae'Rianna Harris had 12 points and 10 rebounds for Purdue (17-12, 8-9). The Boilermakers shot 31% and committed 24 turnovers.

Maryland trailed 12-9 before closing the first quarter with a 10-0 run. It was 19-14 before Jones made three straight layups to up the margin to double-digits.

"It didn't start off as sharp as I wanted it to, but I think it was a little bit with the bye week and the break, but I thought we made some nice adjustments in the second half to get back to playing how we wanted to play," head coach Brenda Frese said. "We spoke of earlier wanting to win at home and steal games on the road, and to be able to go 9-0 at home in conference play for this team is quite an accomplishment given just how tough Big Ten play is."

Purdue committed 15 turnovers and went 9 for 28 from the floor in the first half, which ended with the Terps holding a comfortable 35-22 lead.

Jones had 12 points at halftime on 6-for-8 shooting.

Austin made three baskets, Charles hit a couple of jumpers and Taylor Mikesell drilled a 3-pointer to fuel a 15-3 run at the start of the third quarter that made it 50-25.

Maryland outscored the Boilermakers 28-14 in the period for a 63-36 lead.

Maryland owns the series over Purdue, 11-2, and has won nine of the last 10 matchups.

Charles needs 52 points to become the sixth player in Maryland history to score 2,000. She was one of four seniors honored before her final regular season home game, along with Jones, Blair Watson and Sara Vujacic. 

"Senior Night is always very special to me and to our program," Frese said. "I appreciate everything about this class, they've really worked hard since day one through injuries, adversity, and have always stepped up to accept responsibility. You see their leadership every single day for this team and for this program, so obviously it was really nice to get a tough win over a really good Purdue team."

Next, Maryland will travel to Minnesota (15-12, 5-11) to close the regular season Sunday. The Terrapins and the Gophers will tip off at 4 p.m. ET on ESPN2.
