Duke took care of business on Tuesday night vs. Syracuse to pick up its first ACC win of the season.

The Blue Devils won 86-66 and moved to 10-3 on the season in the process. They also handed Syracuse just their 4th loss of the season.

Here are three takeaways from Duke’s victory:

Elite 3-point shooting

Duke entered the night shooting 36.5% from 3-point range on the year — a well-above-average mark for all division I teams. The Blue Devils had an exceptional night against Syracuse from beyond-the-arc, however, as they made 8-of-17 tries from long range.

Jared McCain continued his hot start to the season by making 4-of-6 attempts from downtown, finishing with 18 points. Jeremy Roach went 2-for-2 from 3-point range.

Defensively, Duke also kept the Orange from getting too hot from distance. Syracuse made just 4-of-16 attempts from beyond the arc.

Mark Mitchell’s great game

It’s been somewhat of a slow start for Mark Mitchell in his sophomore season — at least offensively. His field goal percentage is down slightly from his freshman season and he’s just 1-for-20 from 3-point range to start the year.

However, Mitchell played a phenomenal offensive game against the Orange on Tuesday. He finished the contest with a team-high 21 points on just 10 shots. He missed both of his 3-point attempts, but his overall efficiency didn’t suffer. Mitchell went 7-for-9 from the free throw line and also contributed 6 rebounds, 3 assists and 2 blocks. This was just the second time Mitchell has cleared the 20-point threshold this season.

If Mitchell plays like this through the rest of ACC play, Duke will be very tough to beat.

Tyrese Proctor’s return to form

Tyrese Proctor came off the bench on Tuesday in just his second game removed from an ankle injury he suffered in early December. Proctor missed nearly a month with the ailment, but seems to be hitting his stride as Duke starts ACC play in-earnest.

Proctor scored 14 points on 5-of-7 shooting against the Orange. He went 2-for-4 from beyond the arc and made both of his free throws while also posting a team-high 4 assists.

It’s unclear if Jon Scheyer intends to continue bringing Proctor off the bench for the foreseeable future. But regardless, Proctor is a huge boost to Duke’s rotation when available.

Duke will be in action again on Saturday as it faces Notre Dame on the road.
