Hield scored 19 of his team-high 29 points in the second half to propel OU to an 88-76 victory against Oklahoma Christian on Monday night at McCasland Fieldhouse.
The Eagles held a 41-38 lead at halftime before the Sooners took control in the opening minutes of the second half and didn't look back.
"We just need to pick it up early," Hield said. "We can't wait until the second half to jump on teams. We started off sluggish, but we got our team ready and we got our mojo back together."
Hield connected on 5 of 7 from 3-point range, while the team was 11 of 25 overall, shooting 44 percent from 3-point territory.
Freshman guard Jordan Woodard continued to show signs of why OU fans should be excited about his arrival. Another solid all-around performance as he notched 17 points, six assists, five rebounds and two blocks.
Sophomore guard Je'lon Hornbeak, returning after a one-game suspension, added 12 points with four assists and four steals.
"We came out with much better energy and much more activity in the second half," OU coach Lon Kruger said. "We dictated it a lot more on both ends of the floor. It was really good.
"That's why you play these games – to get some game experience and to get some things you don't see in practice every day."
OU played two games at McCasland Fieldhouse last season, which was where OU played its home games from 1928 through 1975.
With the exhibition schedule in the books, OU opens the season 4 p.m. Friday against Alabama in Dallas.
