INDIANAPOLIS — Cearah Parchment scored 15 points and Destiny Jackson added 14 and five assists, leading Illinois to a 71-69 upset of No. 18 Michigan State on Thursday night in the second round of the Big Ten Tournament.

Maddie Webber scored 13 points off the bench, Jasmine Brown-Hagger 12 and Berry Wallace 11 for the seventh-seeded Illini (21-10), who will play No. 2 seed Iowa in a Friday quarterfinal.

Kennedy Blair poured in a career-high 30 points for No. 7 seed Michigan State (22-8), Grace VanSlooten scored 13 and Jalyn Brown 12.

Illinois held a nine-point lead at 63-54 with 5:39 to play, then held off a furious Spartans rally. Michigan State twice pulled within two in the final 1:11.

On the Spartans’ final possession, VanSlooten collected two rebounds from under the basket before kicking it out to Blair in the midrange. Without a clear shot, she passed it out wide to Brown, who couldn’t save the ball from going out of bounds with one second to play.

Illinois turned over the ball on its first four possessions, forcing a timeout to reset. An 8-0 run gave the Illini their first lead at the end of the first quarter, and they led 36-29 at halftime.

Michigan State had a 9-0 run after the break to regain the lead at 42-41, but a layup and a 3-pointer from Brown-Hagger put Illinois back in front.

Oregon 73, Maryland 68

Ehis Etute and Katie Fiso combined for 32 second-half points to lead Oregon past No. 14 Maryland in the final second-round game Thursday.

After two points from Etute in the first half and none from Fiso, Etute had 18 points, five rebounds and three blocks in the second half. Fiso scored 14 on 7-of-13 shooting and four assists after halftime.

After a back-and-forth in the final three minutes that had Maryland within two points, Avary Cain hit a 3-pointer with five seconds to go to seal the result for the No. 11 seed Ducks (22-11). She had 13 points and two blocks.

Oluchi Okananwa scored 27 points — including 17 in the second half — going 10 of 18 from the field and 7 of 8 at the line to go with three steals for the Terrapins (23-8), the tournament’s No. 6 seed. Isimenme Ozzy-Momodu added 10 points as the only other Maryland player in double figures.

Ohio State 83, Indiana 59

Jaloni Cambridge had 19 points, eight rebounds and five assists, Chance Gray added 18 points and No. 11 Ohio State eased past Indiana in the second round earlier Thursday.

Ohio State (25-6), a No. 5 seed, advances to play 19th-ranked Minnesota in a quarterfinal Friday. The Buckeyes secured their fifth straight season with 25-plus wins.

Cambridge and Gray combined for 10 of Ohio State’s points during a 12-0 run to take the first double-digit lead of the game at 24-14. The Buckeyes’ lead did not drop below eight points the rest of the half, and Gray’s 3-pointer with 20 seconds left made it 36-24 at the break.

Ohio State added a 10-0 run early in the third quarter for a 17-point advantage. The Buckeyes led by as many as 30 points, 81-51, with three minutes to play in the game.

Kennedy Cambridge had 14 points and Elsa Lemmilä grabbed 13 rebounds to go with six points, five assists and three blocks for Ohio State. Gray made four of Ohio State’s 10 3-pointers — a game after the Buckeyes sank a program-record 18 3s in an 87-68 win against then-No. 15 Michigan State on Sunday.

Maya Makalusky led Indiana (18-14) with 21 points and five 3-pointers. Shay Ciezki added 12 points and Nevaeh Caffey scored 10.

Washington 76, USC 64

Elle Ladine scored a season-high 25 points, Avery Howell added 18 points and nine rebounds and Washington defeated USC in the first second-round game.

The eighth-seeded Huskies (22-9) will take on top-seeded and No. 2 UCLA in a Friday quarterfinal.

Hannah Stines scored 12 points, Brynn McGaughy added 10 and Yulia Grabovskaia had 10 rebounds for Washington. Leading scorer Sayvia Sellers (19.2 ppg) dealt with four fouls and had just four points on free throws in 28 minutes. Other Huskies filled the scoring gap with Washington shooting 50% and dominating the boards 44-27 in outscoring the Trojans 40-14 in the paint.

Londynn Jones scored 19 points, Kennedy Smith added 14 and Laura Williams had 13 rebounds to go with nine points for the Trojans (17-13).

Big Ten freshman of the year Jazzy Davidson, who leads the Trojans in scoring, rebounding and assists, scored eight points on 2-of-13 shooting over 29 minutes. Davidson, who appeared to suffer a shoulder injury early, sat out the final seven minutes.

The Huskies led by double figures throughout the second half and by as many as 23. They shot 67% in the third quarter with Ladine scoring eight points to lead 56-36. USC got as close as 10 with two minutes left in the game.

After a first quarter when the teams combined for just 14 points, Ladine scored 13 points on 6-of-7 shooting in the second, including the last six points for a 32-20 halftime edge.
