PITTSBURGH (AP) — It’s one and done for Pittsburgh center Steven Adams and guard Trey Zeigler.

Adams, the 7-foot freshman from New Zealand, said Tuesday he plans to sign with an agent and enter the NBA Draft. Zeigler, a 6-5 junior, announced earlier in the day he was transferring after spending just one season in the program.

The departures could make the Panthers’ move to the ACC a bumpy one. Pitt will join the conference this summer and Adams and Zeigler figured to be key parts of the process after helping the Panthers to a 24-9 record.

Instead both are heading out the door.

“In discussing options with my family and coach (Jamie) Dixon, I feel that it is in my best interest to declare for the NBA Draft,” Adams said in a statement.

Adams started 32 games for Pitt and averaged 7.1 and 6.3 rebounds per game. The 19-year-old led the Panthers with 65 blocks and made 57 percent of his shots while being named to the Big East All-Rookie Team.

Considered a project when he signed, Adams improved as the season went on. He had 13 points and 11 rebounds in Pitt’s 73-55 loss to Wichita State in the second round of the NCAA tournament. Adams said after the defeat he planned to come back but had a change of heart in the last week.

Dixon said he “fully supports” Adams’ decision.

The announcement came barely a week after Dixon signed a new 10-year contract to remain at Pitt and just hours after Zeigler indicated he would seek a transfer rather than play his senior season at Pitt.

Zeigler averaged 4.4 points and 2.0 rebounds in 31 games.
