The former Arizona Wildcats guard poured in 17 points, all of which were scored in the second half, on 6-9 shooting.
Johnson was a perfect 3-3 from 3, and 2-3 from the free throw line in 20 minutes of play.
It was Johnson’s third straight double-figure scoring game with Portland, which beat Toronto, 91-85.
Through five games, Johnson is averaging 8.4 points per game in just 15.6 minutes. He is shooting 56 percent from the field and 7-8 from 3.
The guard had one point, one assist, one steal, one block, two turnovers and five rebounds. Allen missed all three of his field goal attempts and shot just 1-4 from the charity stripe.
Friday is reserved for the consolation round
Friday is an off day for teams in the winner’s bracket, but there will be still be a consolation round.
The only ex-Wildcats playing in it are Kaleb Tarczewski and Lauri Markkanen — and they face each other.
There is a decent chance that neither one plays.
Markkanen sat out Wednesday’s game with a toe injury, while Tarczewski has gotten two DNP-CDs in the last two games.
No matter the result, Summer League will come to a close for both of them Friday, as the consolation round is a one-day, one-game event.
Round 3 of the Summer League playoffs resume Saturday.
