No. 2 Duke’s 13-9 victory over No. 9 Loyola in Baltimore on Saturday was marked by revelations.

First, after the Blue Devils (6-1) had struggled to win 50 percent of their faceoffs this season, they got a 17-for-25 gem out of freshman Joe Stein, who saw meaningful action for the second time.

Duke dominated senior FOGO Mike Orefice and neutralized freshman Bailey Savio, who could be on the verge of taking that job. That dominance served to offset a whopping 22 turnovers by the Blue Devils.

Second, the Duke attack, which is led by senior Justin Guterding and had dominated the Blue Devils’ scoring, took a backseat to the midfield duo of junior Brad Smith and graduate student Peter Conley — the former Hoya who gave Georgetown a superb freshman season before suffering through two injury-shortened years.

Smith and Conley had a hand in all but one of Duke’s goals at Loyola, where the Greyhounds’ defensive midfield had a rough afternoon, causing coach Charley Toomey eventually to double-pole the Duke midfield. Smith and Conley were part of six goals during the game’s decisive 7-0 Duke run.

Smith and Conley each produced four goals and two assists. Smith, who scored three of Duke’s first four goals and assisted on the other, showed his skill early as a jump shooter, a cutter, a dodger and a feeder. He also blew a 20-yard step-down past Greyhounds goalie Jacob Stover midway through the second quarter.

Conley took over the offense in the middle of the game by assisting freshman attackman Joe Robertson late in the second quarter, then by scoring with nine seconds remaining in the first half. His second goal 57 seconds into the second half gave the Blue Devils a 7-4 lead. His two fourth-quarter goals helped to seal the win.

“The beauty of [Saturday] was Brad did not hit one shot in warm-ups,” Duke coach John Danowski said. “For [Smith and Conley] it’s a big deal, because it’s two more guys who have the knowledge that this could be their day.

“We want to create an offense where all six guys are capable of scoring and [we make defenses think] who do you cover? How do you defend us?”
