Jeremy Roach pumped in 22 points and No. 15 Duke used a strong stretch in the second half to take control in a 74-62 victory against Iowa on Tuesday night as part of the Jimmy V Classic in New York.

Mark Mitchell's 17 points and Kyle Filipowski's 12 points and 10 rebounds also helped the Blue Devils (9-2) secure their third straight triumph in a seven-day stretch.

Patrick McCaffrey had 12 points and 10 points, Dasonte Bowen also scored 12 points and Filip Rebraca had 10 for Iowa (6-2), but the Hawkeyes couldn't overcome 3-for-16 shooting on 3-point attempts and 39.7 percent shooting overall.

Kris Murray, who entered the game averaging 21 points for Iowa, was held to eight points on 3-for-9 shooting.

Duke used a 10-2 stretch to break out to a 56-41 lead with less than 12 1/2 minutes to play before both teams failed to score for the next two minutes.

Iowa hit such a rough patch offensively that it managed just four points during a stretch of nearly eight minutes. By then, Duke was up 61-43 and there was no comeback in the forecast.

This was just the second time that a Duke player reached the 20-point mark this season. Roach has done it both times.

Roach scored on consecutive possessions as the Blue Devils stretched the margin to 67-50.

Yet Iowa got to within 68-60 on Payton Sandfort's basket at the 1:19 mark. Roach drained two free throws to thwart the comeback.

Duke led 37-31 at halftime, boosted by 6-for-11 shooting on 3-pointers. The Hawkeyes were just 2-for-9 from deep.

Eight Duke players scored in the first half, led by Roach's 11 points with three 3-pointers. The Blue Devils shot 51.9 percent from the field in the first half.

Duke played three Big Ten Conference opponents in a four-game stretch, falling to Purdue and beating Ohio State before this matchup. Duke leads the series with Iowa 8-1, although this was the first meeting in 21 years.

The Blue Devils improved to 4-0 in the Jimmy V Classic.
