Jesse Kostulias is a freshman RHP with real pitchability and starter upside for New Haven
In the 2026 season, Jesse Kostulias has already seen action for New Haven, including a three-inning outing at TCU where he flashed swing-and-miss stuff but also showed freshman volatility with traffic on the bases and free passes.[1][2] His appeal is the arm talent: prep reports list a fastball that has reached the upper-80s, plus a diverse mix of secondary pitches that suggests he can miss bats and grow into more than a one-pitch arm.[3][6][7] If you want a projectable right-hander with room to develop, he’s worth a close look.[2][3][6]
