IOWA CITY - Jared Jeffries scored 26 points and Kyle Hornsby hit two 3-pointers during a 13-0 first-half run as Indiana upset No. 13 Iowa 77-66 Sunday to stay unbeaten in the Big Ten.
Indiana, off to its best start in the league since the 1992-93 season, made eight 3-pointers in building an 11-point halftime lead and answered every Iowa threat in the second half.
Iowa rallied from 17 down at halftime to beat Indiana last season. But the Hoosiers contained Iowa scoring leaders Luke Recker and Reggie Evans this time and forced the Hawkeyes into 15 turnovers.
Recker, who played his first two seasons at Indiana, scored only two points in the first half and finished with 12 before fouling out with 38 seconds left. Evans, averaging 18.3 points, scored only seven, a season low.
Ryan Hogan led Iowa with 15 points. Tom Coverdale added 15 for Indiana and Hornsby had 11.
Down 16, Iowa made a late run and four times closed within eight points, but Indiana responded with a basket or free throws on each occasion. Jeffries scored on a putback to make it 69-59 with 2:19 left, and Hornsby got free for a layup for a 71-61 lead with 1:52 to play.
The Hoosiers had no trouble holding after that.
Jeffries was resting in the first half when Indiana, trailing 22-21, took control.
The Hoosiers started the surge with three straight 3-pointers, two by Hornsby and one by Coverdale. Coverdale then stole the ball and drove for a layup, and Jeff Newton got a basket inside after Recker fell trying to put up a shot.
Iowa coach Steve Alford twice called a timeout to try to slow the Hoosiers before Iowa's Duez Henderson finally broke the run with a 3-pointer. Hogan's 3 left Iowa trailing 38-29, but Donald Perry hit a jumper just before the buzzer to give Indiana its 11-point halftime lead.
Recker's 3-pointer drew Iowa to 42-37 early in the second half, and it looked as if the Hawkeyes might rally. But Jeffries scored six straight points, and Dane Fife hit back-to-back 3-pointers, increasing the lead to 55-39.
