The 6-foot-1, 200-pound Robinson totaled 21 points, including three three-pointers, as top-seeded Chester moved closer to its third consecutive district championship. The Clippers will play No. 2 Lower Merion at 9 p.m. Friday at Villanova's Pavilion.
"That's the game people expected and wanted," said Yarbray, whose squad bested Lower Merion, 61-53, in last year's district final. "Friday night will be a big night. We'll be ready."
Robinson shot 6 for 11 from the field (3 for 5 from beyond the arc) and 6 for 6 from the line.
Said Yarbray: "He broke his foot last summer. He didn't start playing until the second week of November. He's finally getting his legs, his wind. He's not just settling for jump shots."
Against the fifth-seeded Ghosts, senior swingman Rondae Jefferson produced 14 rebounds, 13 points, and 4 steals. Richard Granberry, a 6-7 forward, managed 10 points and nine boards.
Ahead by 32-31 in the third quarter, Chester (23-3) made it 52-32 in what seemed like an instant. Robinson and company forced eight turnovers in that frame.
"We really got up on them and started playing hard," Robinson said. "They started rushing things, throwing the ball away. It went just the way we wanted."
Overall, the Ghosts (21-5) shot 13 for 46 from the field and committed 19 turnovers. They hit only three field goals in the second half.
"Those guys are big, they play hard, and they play every possession," Abington coach Charles Grasty said. "Chester is Chester. You have to limit your mistakes."
For the Clippers, James Kirksey chipped in nine points off the bench. His putback during the 20-1 burst made it 44-31.
Sophomore swingman Matt Penecale and senior guard Jordan Simmons notched 14 and 12 points, respectively, for Abington.
Of Chester's 47 rebounds, 21 came on offense.
Abington 13 11 8 11 – 43
