The story of the 2024 ISL season will be a St. Sebastian's freshman taking the league by storm.
Sebs '27 Gavin Wainwright finished off an unexpected ascent to the top of the ISL hierarchy of future D1 college pitchers with another shutout on the mound, this time in the ISL championship game. Top-seed St. Sebastian's finished off a surprisingly dominant season with an ISL-clinching 2-0 win over second-seed Lawrence Academy in the ISL championship game at St. Sebastian's School. It is St. Sebastian's School's first ISL title since 2018.
A relatively unknown NEB position-player heading into the season, Wainwright served as the trump card for St. Sebastian's under first-year head coach Matt Duffy, a former big-leaguer who was once a St. Sebs ISL Player of the Year in his own right. Wainwright lifted a team that finished sixth in the ISL last year to the No. 1 seed with 28.1 scoreless innings in the regular season en route to a 4-0 record and 0.00 ERA.
He managed to raise his level of play in the playoffs, earning two wins and a save in three playoff games. He allowed just one run in 15 innings, including complete games against Roxbury Latin and Lawrence Academy. In the opening round game against Roxbury Latin, he outdueled one of New England's top prep prospects in the Class of 2026, James Gibbons, to the tune of a 6-1 victory. In the championship game, he outdueled Duke commit and former First Team All-ISL selection John Paone in a 2-0 victory.
