NEW YORK (AP) -- Notre Dame coach Muffet McGraw isn't impressed by her team's 12-game winning streak.

"It's who you play," McGraw said. "We haven't beat a ranked team in those 12 games. The winning streak doesn't mean anything to me."

	Danielle Green and Notre Dame drove right past Ana Pericic and St. John's on Wednesday.

A 69-49 victory over St. John's on Wednesday night gave the fifth-ranked Fighting Irish (16-2, 7-0 Big East) their longest winning streak since the 1990-91 season, when they won a school-record 15 straight.

The Irish have not lost since a 71-61 defeat to defending national champion Purdue on Dec. 8. Overshadowing the streak were 15 first-half turnovers against the Red Storm.

"It's mental, they didn't even press," McGraw said. "That's a problem we need to fix. We can't afford to take teams lightly."

St. John's (6-12, 1-7) led 14-13 on a basket by Latasha Thompson before the Irish went on a 12-1 run to lead 25-15 with 8:19 remaining in the half.

Behind Danielle Green's 11 first-half points and some solid defense, Notre Dame led 33-19 at halftime and held St. John's to a season-low 19-percent shooting (6-for-32).

Notre Dame center Ruth Riley scored 12 of her 16 points in the second half, reaching double figures for the 16th time in 18 games.

Because of the snowstorm that blanketed the Northeast, the team stayed overnight in Pittsburgh before arriving in New York on Wednesday afternoon.

Riley didn't want to blame travel delays for her slow start.

"We were just out of it," she said. "We needed to take care of the ball. Turnovers really hurt us."

In the second half, the Red Storm came within 52-42 with 6:35 remaining. But Notre Dame went on a 15-0 run, holding St. John's without a field goal for five minutes until Aiysha Smith's layup made it 67-44 with 1:40 remaining.

"We went into shooting slumps, and that's what is disappointing," St. John's coach Darcel Estep said. "When you do a great job forcing turnovers, then you need to capitalize."

Green, making her seventh start of the season, finished with 16 points and six assists for the Irish. Niele Ivey, eighth in the nation with 7.0 assists per game, finished with eight points and one assist.

Thompson had a team-high 20 points for St. John's, which shot 24 percent for the game. Smith added 10 points and 10 rebounds.

Notre Dame, which finished with 22 turnovers, shot 55 percent in the second half (16-for-29).

The Irish, whose defense is holding Big East opponents to just 54.8 points per game, held the Red Storm to 2-of-15 from 3-point range.

Notre Dame's streak will be tested next month when it faces ranked Big East foes Boston College, Rutgers and top-ranked Connecticut.

The Irish are tied with the Huskies (18-0, 7-0) atop the Big East standings.
