Walk-on Alex Barlow's bucket with 2.3 seconds left gave Butler an 88-86 win over No. 1 Indiana on Saturday in the Crossroads Classic.
Barlow drove to the hoop, posted up, spun and flipped in the game winner up from inside the paint to help the Bulldogs claim their first-ever win over a No. 1 ranked team.
The Bulldogs won in overtime after two starters fouled out in regulation and a key reserve fouled out in the extra period.
Rotnei Clarke scored 19 points, Roosevelt Jones had 16 points, 12 rebounds and seven assists and Andrew Smith added 12 points and nine rebounds for the Bulldogs (8-2). It was Butler's fifth straight win.
Victor Oladipo and Cody Zeller each scored 18 points for Indiana (9-1).

Zeller came back with a layup to tie the score with 19.3 seconds to go. Barlow scored, and Jordan Hulls missed a long shot at the buzzer.
Indiana led 37-33 at halftime, but Butler opened the second half with a baseline fadeaway by Khyle Marshall that cut Indiana's lead to 37-35. Indiana quickly responded, and a steal and dunk by Oladipo made it 42-35 and forced Butler to call a timeout.
The Bulldogs rallied, and a 3-pointer and layup by Clarke helped Butler cut Indiana's lead to 47-46.
Butler's Jones and Smith, who had left the game with four fouls, re-entered with 9 minutes remaining and the Bulldogs trailing 57-50.
