Last year, a quiet performance from Myles Powell likely would have led to defeat for Seton Hall. Even as recently as a month ago, the Pirates needed offensive explosions from him to prevail.

But not now. Not with the way their supporting cast is performing.

Stifled by talented Providence defender David Duke and frequent double-teams, Powell wasn’t his usual productive self. The National Player of the Year candidate’s looks were limited, his openings were nonexistent and he attempted just six shots.

And it didn’t matter.

His teammates picked up the slack, leading the No. 10 Pirates (15-4, 7-0 Big East) to their ninth straight victory, 73-64 over Providence on Wednesday night in front of 9,267 at Prudential Center.

“I just feel like we’re showing everybody across the country it’s not just the Myles Powell show,” Powell, who scored 14 points, said after Seton Hall equaled its longest winning streak since 2002-03, when it also won nine in a row.

Ever-improving center Romaro Gill brought the house down late in the second half, throwing down a highlight-reel slam from outside of the paint as the shot clock was winding down to push the Pirates’ lead to nine. It was the exclamation point to another brilliant night from the 7-foot-2 Jamaica native, who finished with 17 points, eight blocks and six rebounds. Gill has now reached double figures in six straight games.

“I did it in practice, but with nobody guarding me,” he said of the slam.

Added Powell: “He’s definitely changing his life on that basketball court.”

Jared Rhoden continued to fill in ably for injured Seton Hall starter Sandro Mamukelashvili (fractured right wrist), with 15 points and eight rebounds, and Quincy McKnight was again a rock at the point, with 11 points and eight assists.

Rhoden spearheaded a 10-4 run, sinking a baby jumper and putting back his own offensive rebound, to give the Pirates a commanding 63-54 lead with 5:55 left. Appropriately, Powell (14 points) was on the bench for the end of the spurt as the Pirates didn’t need his best. When the Friars (11-9, 4-3) got within five in the final minute, Rhoden put them away with a backdoor layup on a McKnight feed, as the Pirates led from the final minute of the first half through the final horn.

“Everybody’s locked in,” Powell said. “Everybody’s coming into practice with a great mindset. Everybody wants to get better. We see how we’re winning, and we don’t want to change anything up.”

It has been quite a turnaround for Seton Hall, which is 7-0 in the Big East for the first time in program history. Just five weeks ago, the Pirates were reeling, losing two straight games. Mamukelashvili and Powell (concussion) were hurt. The supporting cast got the ball rolling in the right direction with an upset of No. 17 Maryland and they haven’t lost since.

“All these guys have great confidence now,” coach Kevin Willard said after equaling P.J. Carlesimo for most Big East wins by a Seton Hall coach with 78.

“That’s kind of grown from when [Powell] went down. All these guys understood that they can’t just depend on him. That’s been [our] biggest growth.”Willard said Mamukelashvili, out since Dec. 8, won’t be able to return for next Wednesday’s game against DePaul as initially expected. He has yet to be cleared to practice.
