Colin Rolfe made it 2-0 seven minutes later, and the Cardinals padded their lead in the second half thanks to a second goal from Rolfe and a goal by Mark Knight. Indiana had sophomore forward Will Bruin sent off for dissent. He will miss Sunday's Big Ten match at No. 12 Northwestern.
Indiana fell to 7-6-1 with the loss. Five of its losses have been to teams ranked in the top 16: No. 1 Akron, No. 3 Wake Forest, No. 8 UC Santa Barbara, No. 11 Louisville and No. 16 Butler.

* ATTINELLA SAVES USF. The Big East is loaded this season with top-flight goalies -- most notably Josh Ford, who has eight shutouts in a row for Connecticut, and Zach Johnson, who has allowed only two goals in West Virginia's last nine games. One of the best is Jeff Attinella, who came up big again for South Florida in the No. 7 Bulls' 1-0 win over No. 18 Dartmouth. Midfielder Jorge Mora put USF ahead in the 27th minute, but the visitors from the Ivy League had plenty of chances. Attinella finished with eight saves, making several big stops in the second half.
* TULSA FALLS ON 70-YARD GOAL. No. 17 Tulsa had its 20-game unbeaten streak in Conference-USA regular-season play snapped when the Golden Hurricane fell at home to SMU, 3-2, in the pouring rain. "I think we started the game like we wanted to do," Tulsa coach Tom McIntosh said. "Our play in the backfield was poor tonight, and we gave away three easy goals." The third came when Ryan Rosenbaum's clearance from 70 yards out bounced over Tulsa keeper Andy Aguilar's head and into the goal.
