Costa dazzles in debut, York rolls past Southern Maryland 11-1

Julian Costa did not look like a rookie getting his first look at professional baseball. He looked like a rotation answer, and York may have found him at exactly the right time. The 23-year-old left-hander carved through Southern Maryland for 6.2 scoreless innings on Father’s Day afternoon at WellSpan Park, and the Revolution rode that debut to an 11-1 win that snapped back from a rough day before.

Costa gave up only two hits, walked two and struck out four in his first professional appearance. At one point, he retired 12 straight and carried a one-hit shutout into the seventh before Danny Bautista Jr. finally broke through with a two-out single. Even then, the moment never really tilted away from Costa. The crowd gave him an ovation as he left, and Ryan Shreve finished the seventh by striking out Ethan Wilson to keep the shutout intact.

That kind of poise is exactly why York signed Costa after his decorated run at West Chester University. He went 13-2 with a 2.59 ERA in 2026, struck out 88 batters in 97.1 innings, and finished his college career with program records for wins, strikeouts and innings pitched. Costa also threw four complete games, three shutouts and a no-hitter against Frostburg State in early March, then finished as the Division II active leader in career wins and shutouts and second among active Division II pitchers with 305 strikeouts. The accolades followed: D2CCA Second Team All-American and NCBWA Honorable Mention All-American.

York did not waste the debut. The Revolution piled up 17 hits, had every starter reach safely with at least one hit and scored in six of the first seven innings. Nick Dunn doubled to start the offensive tone, Brian Rey drove him in and stretched his hitting streak to eight games while extending his on-base streak to 27 straight, and the lineup kept stacking traffic from there. Devonte Brown, Cole Griffith, Tomo Otosaka, Jacob Teter, Mike Rosario, Jackson Ross and Ben Blackwell all chipped in as York built a 6-0 lead before blowing the game open with a four-run seventh.

The timing mattered as much as the margin. York had dropped a 9-2 game to Southern Maryland on June 20 and had been blitzed 24-12 by the Blue Crabs on June 17, a loss that set the franchise record for runs allowed in a game. Instead of letting that spiral continue, York answered with its third three-hitter of the season and its first in a nine-inning game. In a North Division race where every divisional meeting carries extra weight, Costa’s debut looked less like a novelty and more like a first step toward stabilizing the rotation.
