Jake Robinson has played the role of Montour’s closer this season.

But on Monday, this closer became a starter, and his sparkling performance now has Montour a step closer from playing for a WPIAL Class 4A title for the third year in a row.

Making his first start of the season, Robinson scattered four hits, didn’t walk a batter and had 10 strikeouts to lead No. 1 Montour to a 2-0 win against No. 9 Hampton in a quarterfinal at West Mifflin.

“He had rattled off five straight saves in some tight games and had really established himself over the last month. He really earned the opportunity,” Montour coach Bob Janeda said of Robinson, a junior right-hander who improved to 3-0 with a 1.59 ERA on the season.

The win moves Montour (19-3) into Tuesday’s semifinals, where the Spartans will meet Latrobe at Boyce Mayview Park. The Spartans were the WPIAL runner-up in 2021 and 2022.

Robinson outdueled Hampton left-hander Ryan Apaliski, a James Madison recruit who allowed only three hits and struck out eight while going the distance.

“His fastball was really working,” Janeda said of Robinson. “He was ahead of 70% of the hitters.”

Montour tallied the game’s only runs in the second and third innings. Maddox Tarquinio scored on an error in the second and Robinson doubled home Zac Stern in the third.

With Robinson pitching Monday, Janeda said Montour will turn to ace Vinnie Markulin to face Latrobe. Markulin is 6-0 with a 1.35 ERA this season.
