WEST LAFAYETTE, Ind. (AP) — Keita Bates-Diop scored 18 points, including the decisive putback with 2.8 seconds left, to give No. 14 Ohio State a 64-63 upset at No. 3 Purdue, ending the nation’s longest winning streak at 19 games Wednesday night.
The Buckeyes (21-2, 12-1 Big Ten) grabbed a share of the conference lead as Ohio State won for the 11th time in 12 games.
Carsen Edwards finished with a career-high 28 points to lead the Boilermakers (23-3, 12-1), who lost for the first time since Nov. 23.  Isaac Haas had 18 points but missed an 8-foot jumper at the buzzer to win it.
Purdue’s school record 14-game winning streak in conference play and 21-game winning streak at home also ended with a surprising finish.
Purdue led 58-51 with 5:29 to go, but Ohio State closed the game on 13-5 run, retaking a 62-60 lead on Wesson’s banked 3-pointer 1:13 to go.
Twenty-four seconds later, Vincent Edwards answered with a three-point play that gave Purdue the lead.
But on the Buckeyes’ final possession, they grabbed two offensive rebounds — the second being Bates-Diep’s putback to win it.
BIG PICTURE
Ohio State: The Buckeyes’ come-from-behind victory just turned the Big Ten back into an interesting race. A loss would have left Ohio State two games behind Purdue and down a tiebreaker. Now, the Buckeyes have a share of the lead and own the tiebreaker over Purdue with less than two weeks to go.
Purdue: The hottest team in America just kept finding ways to win — until their shooting touch went awry Wednesday. Make no mistake, Purdue remains one of the nation’s best teams and still could win a second straight conference crown. But losing this one, on the same night No. 1 Villanova also lost, hurts.
