PHILADELPHIA — Seth Allen showed off his 38-inch vertical leap with a rim-rattling, right-handed dunk in the second quarter of a game here at the Reebok Breakout Challenge on Thursday afternoon.

Allen, a senior-to-be at the Fredericksburg Christian School, said he is still playing as if he has something to prove even though he has already made an oral commitment to Maryland Coach Mark Turgeon.

“I am very excited about Maryland,” Allen said. “But I am playing right now like I don’t have a scholarship, like I am still fighting for one.”

Allen had two assists, two steals and six points in the second quarter alone Thursday afternoon. In the fourth quarter, Allen had a head-to-head matchup with sinewy guard Jonathan Milligan, whom Washington Wizards guard John Wall said has been the star of the camp. (Wall is here to help run the camp and work with players.)

Mulligan penetrated on Allen and converted a layup. Other than that, neither stood out in the head-to-head matchup.

Allen, a point guard who looks to score, did not seem limited by a left ankle injury that kept him out of the NBPA Top 100 Camp in mid-June. Allen said his ankle is at 90 percent right now and he expects it to be fully healthy when he competes in an event next week in Morgantown, W.Va.

Allen is not ranked among the nation’s top 150 of the most recent rankings on, largely because he is new on the national scene and has been hampered by the injury in recent weeks.

“As long as Maryland knows what I am capable of, it doesn’t really matter about anything else,” Allen said.

Asked about what attracted him to Maryland, Allen spoke of his close relationship with Turgeon.

“He’s a former point guard, and he gives a lot of attention to point guards,” Allen said. “He is calm. I can trust him. And I can talk to him about anything.”

Allen said he takes pride in the fact he was Turgeon’s first prospect to commit to Maryland, adding that “as long as he is the coach at Maryland, I’ll always be the first.”
