The Golden Hawks, ranked No. 10 in Southeastern Pennsylvania by The Inquirer, improved to 6-1 overall and 4-1 in National Conference action.
Paprocki, who doubles as an outfielder, grew up playing Little League baseball for Holland. Many of North's players suited up for rival Newtown.
"Whenever you're going to play North, you're really anxious in school," Paprocki said. "You're sitting in your chair and biting your nails, tapping your feet. You live for games like this."
In the latest chapter of the 12-year rivalry, Paprocki held the Indians (6-3, 4-3 conference) to three hits though six innings. Down by 3-0, North, with the aid of two errors, closed the gap to one in its final at-bat.
"I started kind of slow, was leaving my breaking ball up," Paprocki said. "In the fifth, when I got three outs on pop-ups, that was a big turning point."
Paprocki, who will pitch at La Salle University, mixes a fastball clocked in the mid-80-m.p.h. range - he topped out at 88 last summer - slider, curveball, and change-up.
Of his slider, the 18-year-old said: "That's probably my out pitch. When I can locate it well, it gives me the upper hand on batters."
In choosing to play baseball at La Salle, Paprocki said Explorers coach Mike Lake was "definitely the main reason. He shows he cares about you and your studies."
Paprocki, who was a two-year starter at quarterback in football, plays summer ball with the Philly Bandits.
