Notre Dame gave up five unearned runs to Seton Hall in the seventh inning as the Pirates defeated the Irish 9-4 on Saturday afternoon at Frank Eck Stadium.
The loss snaps Notre Dame's six-game winning streak and drops the Irish to 13-6 on the season and 1-1 in the Big East. Seton Hall jumps to 9-7 overall and 1-1 in the league.
Seton Hall opened the game with a run in the top of the first and added two more in the second. But Notre Dame starter Brian Dupra settled down after that, retiring 15 of the next 18 batters he faced.
Dupra retired the first two hitters he faced in the seventh, but allowed back-to-back singles and was replaced after an error and a double made it 5-3. With two runners on, Joe Spano walked the only batter he faced to load the bases.
Will Hudgins induced a ground ball, but another error followed by consecutive bases-loaded walks gave Seton Hall an 8-3 advantage.
Dupra's final line was 6.2 innings pitched, seven runs, three earned, nine hits, three strikeouts and three walks with the loss.
Seton Hall starter Keith Cantwell limited the Irish to six hits and four runs in eight-plus innings, but was replaced in the ninth when Evan Sharpley led off with a homer and Barnes walked. Any chance Notre Dame had at a late rally ended when Matt Singer induced a double-play and a groundout to end the game.
The series concludes with the rubber game at 12:05 on Sunday. Eric Maust will start on the mound for the Irish.
