"He had them all working today," Northern Burlington coach Rick Doppler said.
Northern Burlington (17-3) will meet Pennsville, a 10-6 winner over Cinnaminson on Saturday, in a quarterfinal at 10:30 a.m. next Saturday at Washington Township.
"We lost here in the first round last year, and we didn't want the same thing to happen," Gakeler said. "This was a good win for us."
It was a game between Atlantic Coast Conference pitching recruits, and for the first three innings it lived up to its billing.
Haddonfield righthander Mark Ostbye, a Virginia recruit, opened with two shutout innings before Northern Burlington scored two unearned runs in the third on Gakeler's two-out, two-run double to center field.
The Greyhounds blew the game open with seven runs in the fifth. Shortstop Tyler O'Dell, who was 3 for 3 with a walk, two runs scored, and three RBIs, and Gakeler (2 for 3 with three RBIs) led the potent Northern Burlington attack.
Haddonfield (14-4) committed five errors.
"It is the worst we played all year defensively," said Haddonfield coach Bob Bickel, who also had plenty of praise for Gakeler.
"He was outstanding," Bickel said. "We have seen good pitchers this year, but in terms of command of more than one pitch, he's been the best."
Haddonfield 000 000 - 0 2 5
