NEW YORK -- N.C. State's red-hot second-half shooting helped erase a 17-point deficit that Jerome Robinson helped Boston College build.
But Robinson made the plays at the end to seal the Eagles' upset anyway.
In a game that saw five ties in the final five minutes, Robinson's jumper with 17.8 seconds left put Boston College up for good and his steal with 11.8 seconds left helped the Eagles post a 91-87 ACC tournament win Wednesday at the Barclays Center.
Robinson scored 26 points for No. 12 seed Boston College (19-14), which advances to Thursday's quarterfinals to meet No. 4 seed Clemson (22-8). Ky Bowman added 24 points for the Eagles.
"It's big for me," Robinson said. "I think it's big for the team as well. We lost to them earlier in the year at N.C. State (82-66) and just to get them back in the tournament definitely feels good."
N.C. State (21-11) will await Sunday's NCAA Tournament selection show to learn its postseason fate.
"For whatever reason, we didn't play extremely well to start the game," N.C. State coach Kevin Keatts said. "But what we'll take from this is that when it's one-and-done, you've got to play the entire game. You've got to finish games."
Boston College outplayed the Wolfpack in the first half to lead 45-31 before pushing its lead to 51-34 early in the second half.
But N.C. State mounted a stirring comeback that saw it make 22 of 30 second-half shots (73 percent).
Allerik Freeman finished with 21 points for the Wolfpack while Omer Yurtseven scored 20. Torin Dorn scored 13 points for N.C. State despite playing just four minutes in the first half due to foul trouble.
