EAST LANSING, Mich. (AP) -- Raymar Morgan scored 14 of his 16 points in the second half and No. 19 Michigan State beat Iowa 66-52 on Saturday, coach Tom Izzo's 300th career win with the Spartans.
Six weeks after a humbling 43-36 loss to the Hawkeyes, the Spartans (22-5, 10-4 Big Ten) jumped to a 20-1 lead over the opening 10:20 and were never seriously threatened.
Michigan State committed a season-low five turnovers, 13 fewer than it had in Iowa City.
Drew Neitzel had 12 points and Drew Naymick grabbed eight rebounds for the Spartans, who also answered an 85-76 upset at Penn State three weeks ago with an 86-49 win on Wednesday.
Cyrus Tate led Iowa (12-16, 5-10) with a career-high 26 points and nine rebounds, shooting 10-for-13 from the field and 6-for-7 at the line.
The Hawkeyes missed their first nine shots of the game. They rallied to shoot 56.5 percent in the second half but couldn't cut into a 31-18 halftime lead.
Michigan State won its 20th straight at the Breslin Center and moved to 180-22 at home Izzo's 13 seasons.
