Michigan State made five 3-pointers in less than 3 minutes, making up for what was otherwise a lackluster performance.

Kalin Lucas scored six of his 20 points on 3-pointers during the first-half barrage that gave the eighth-ranked Spartans the lead for a good in a 67-58 win over Ohio State on Tuesday night.

‘‘We were up and we let our guard down,’’ Buckeyes forward Evan Turner said. ‘‘They got shots all over the perimeter and the momentum changed.’’

Michigan State has won eight straight since being routed by North Carolina and 26 in a row at home, dating to a loss against Ohio State nearly two years ago, but coach Tom Izzo was underwhelmed by the latest victory.

‘‘We looked tired and we played tired,’’ Izzo said. ‘‘We’re going to have our first day off tomorrow in a couple of weeks and that will be good for all of us.’’

Then, Michigan State (12-2, 3-0 Big Ten) will start preparing for a visit from the defending national champion Kansas Jayhawks on Saturday.

‘‘If we’re not ready to run in that game, we’re going to get run out of the gym because they’re very athletic,’’ Izzo said. ‘‘We have to get freshened up.’’

Ohio State’s William Buford scored 17, B.J. Mullens had 16 points and Turner added 14.

The Buckeyes (10-3, 1-2) have lost three of four after starting 9-0, hurting without their most experienced player, David Lighty, who is out with a broken foot.
