The Allen Fieldhouse magic -- and a blistering shooting performance -- helped No. 13 Kansas to a 78-67 win over short-handed Ohio State on Saturday, the Jayhawks' 47th consecutive non-conference home win.

The Jayhawks (7-2) shot a staggering 58.3 percent from the field, including 68 percent in the first half. Thomas Robinson led the way with 21 points, Elijah Johnson added 15 on five 3-pointers and Kevin Young scored 14 off the bench.

The second-ranked Buckeyes (8-1) made their first trip away from home without All-American Jared Sullinger -- their leading scorer and rebounder -- who missed a second consecutive game with a sore back.

After trailing for only 2 minutes, 57 seconds over its previous six games and never trailing in its previous two, Ohio State never led Saturday. They were tied at 2 with 17:53 left in the first half and trailed the rest of the game.

Without Sullinger, the Buckeyes had no answer for Robinson, and they had a tough time settling into their offense without the catalyst. William Buford heated up in the second half to score a team-high 21, and Deshaun Thomas added 19, but Kansas' bench outscored the Buckeyes' reserves 21-4.

Kansas improved to 36-20 against ranked opponents under Bill Self, including a 4-1 mark against teams ranked first or second.
