RAYMOND — The formula for Porters Chapel Academy Monday night was simple: Get the ball to the big men and repeat as often as possible.

Jacob Rachal scored a game-high 23 points and grabbed 10 rebounds and fellow big man Jermaine O’Connor had 17 points, snagged 14 rebounds and blocked five shots as the Eagles advanced to Wednesday’s South State quarterfinals with a 75-51 thumping of Lamar Christian.

“People were over there saying what great position they were getting and I was like, ‘Lord, how could they not?” Porters Chapel coach E.J. Creel said of her team’s dominance down low. “Lamar is a scrappy little team and they never quit.”

O’Connor and Rachal were easily taller than any player Lamar had and it showed throughout. Rachal scored 19 of his points in the second and third quarters and played only sparingly in the fourth. O’Connor came off the bench and had nine of his 17 in the first half. Matt Cranfield poured in 11 points, including a pair of 3-pointers, and Luke Willis scored 10.

Wednesday’s matchup with top-seeded Riverdale will show little resemblance to what the Eagles saw from Lamar Christian, a school based in Purvis.

PCA led 35-20 at halftime. As good as PCA was playing, Creel sensed impatience from her club.

“We have to be more disciplined,” said Creel, who is expecting her second child within days.

Lamar cut the deficit to nine at 35-26 two minutes into the third quarter before Porters Chapel connected on its next eight shots to rebuild the lead comfortably into double figures.
