Pöllä, a 6-foot-11, 265-pound center out of Helsinki Basketball Academy, took an official visit to Oklahoma a week ago. During his trip, he also took official visits to Penn State and Tulane.
"He had three real good choices and I think with Oklahoma, everything came together," Helsinki Basketball Academy coach Hanno Möttölä told Scout. "He wants to play at the highest level and play for an extremely good coach. Obviously, I played for coach Kruger, so it was a situation where he felt very comfortable and he had a great visit. The intriguing part at a high-level program like Oklahoma is they want to make him a feature center."
Pöllä played for Finland’s U18 team in the 2016 Nordic Championship, averaging 7.6 points and 8.2 rebounds through five games.
"Hannes is a scorer on the block and an offensive force," Möttölä added. "In todays game coaches are looking for athletic big guys that can screen and roll, but from talking to coach Kruger they'll use him differently. Hannes felt comfortable that he’ll be able to be a center and not a screener and rebounder. He’s an old school center that will translate in the Big 12."
The addition of Pöllä gives Oklahoma their second pledge in the class. He joins 2017 top 100 prospect Brady Manek to make up their two-man class.
