Baseball games are nine innings long and Notre Dame used all nine of them to get by Rice in the second of the season opening three game series on Saturday.
Trailing 4-3 entering the eighth inning, Notre Dame rallied for three runs in both the eighth and ninth innings to earn a 9-5 victory and secure a season-opening series win.
David Glancy led off the eighth inning with a game-tying solo home run before a two run home run by Simon Baumgardt a few batters later put the Irish ahead for the first time since the top of the first inning.
Rory Fox recorded two outs in the eighth inning before Nate Hardman recorded the final four outs to secure the Notre Dame win.
The 2-0 Irish look for a sweep of Rice on Sunday in the finale that gets underway at 2:00 p.m. ET in Houston.
