COLUMBUS, Ohio All season, Ohio State's fans wondered whether Aaron Craft one of the nation's top defenders would make major contributions at the other end of the court.
He picked the perfect time to break loose.
Craft continually slashed through the lane for a career-high 21 points on Sunday more than he had scored in the last three games combined to lead the 18th-ranked Buckeyes to a 68-60 victory over No. 4 Michigan State.
"Give Aaron Craft credit. In the second half, he tore us apart," Spartans coach Tom Izzo said. "It was Aaron Craft. He beat us every way you could beat us."
The pesky junior defensive specialist hit 7 of 12 shots almost all on drives through a thicket of players in the paint.
The loss crippled the Spartans' hopes of catching top-ranked Indiana, which leads the Big Ten Conference race by 1 1/2 games with four remaining.
Freshman Gary Harris had 14 points, Derrick Nix 12 and Adreian Payne 12 (with 15 rebounds) for the Spartans (22-6, 11-4), who have dropped two in a row after winning 11 of 12.
Ohio State also boosted its flagging postseason résumé. The Buckeyes (20-7, 10-5) came in having won just one game in eight starts against teams in the Associated Press Top 25 but were 18-0 against unranked teams.
Counting a 56-53 win over No. 2 Michigan on Jan. 13, it was the first time that Ohio State has beaten two top-5 teams at home in one season.

UCLA 75, USC 59 in Los Angeles Jordan Adams scored 20 points, four others scored at least 10 points, and the visiting Bruins (20-7, 10-4 Pacific-12) never trailed against the Trojans (12-15, 7-7).
