4:28pm: Isaiah Miller has a contract agreement with the Trail Blazers, tweets Chris Haynes of Yahoo Sports. The free agent guard will be given an opportunity to win a roster spot in training camp, sources tell Haynes.
Miller, 24, signed an Exhibit 10 deal with the Timberwolves last September after going undrafted out of UNC Greensboro. He spent the season in the G League as an affiliate player with the Iowa Wolves, averaging 12.7 points, 4.7 rebounds and 3.2 assists in 32 games.
Miller attended a free agent mini-camp with the Jazz in early June and earned a spot on Utah’s Summer League roster. He appeared in two games and averaged 5.0 PPG.
Portland currently has 15 players with guaranteed contracts, but only one of the team’s two-way slots is filled.
