The 21-year-old former Newcastle Hunters junior added seven rebounds and eight assists in another performance that was highlighted by a ridiculous right-handed put-back jam in the fourth quarter as the Sixers won on the road to improve their season record to 2-4.

Boomers big man Aron Baynes had six points and five rebounds in Boston's 96-90 win over Miami, with Kyrie Irving scoring nine of his 24 points in the final 2:03min.
"Just big possessions down the stretch (and) understanding you have to stay poised," Irving said.
Jayson Tatum scored 20 and Marcus Smart added 16 for the Celtics, who made it four wins on the trot after two losses to start their season.
A DeMarcus Cousins triple-double, of 29 points, 12 rebounds and 10 assists, and 30 points from Anthony Davis helped New Orleans beat Cleveland 123-101.

Saturday's other winners were Oklahoma City Thunder and the Memphis Grizzlies.
