Top 30 at Top 75

Group 1 for both the host and visitor

No. 3 Michigan State Spartans (17-2, 8-0) at No. 22 Iowa Hawkeyes (16-3, 5-3), 7 p.m. (FS1)
No. 27 North Carolina State Wolfpack (15-3, 3-2) at No. 13 Louisville Cardinals (13-5, 4-1), 8 p.m. (Raycom (regional)/ACCNE)

The Spartans will look for a repeat of the 90-68 hammering they delivered to the Hawkeyes back on December 3rd, while the Wolfpack, a team that needs a Group 1 win badly, visits the Cardinals for the pair’s only meeting of the regular season.

31-75 at Top 75

Group 1 for the visitor only; Group 2 for the host

No. 66 Memphis Tigers (12-6, 4-1) at No. 62 Temple Owls (14-4, 4-1), 7 p.m. (CBSSN)
No. 40 Washington Huskies (14-4, 5-0) at No. 67 Oregon Ducks (11-7, 2-3), 9 p.m. (ESPN2)

The Owls and Huskies currently rank ahead of the Tigers and Ducks in the bubble pecking order, but that might change with losses tonight. At least Temple gets a Memphis team that’s won three straight and seven of eight in its own building. Note that this is the first of five road games Washington will play in its next seven.

31-75 at 76-135

Group 2 for both the host and the visitor

No. 54 Arizona Wildcats (14-5, 5-1) at No. 98 USC Trojans (10-8, 3-2), 9 p.m. (FS1)
No. 47 Saint Mary’s Gaels (13-7, 4-1) at No. 111 BYU Cougars (12-9, 4-2), 11 p.m. (ESPN2)
No. 69 Arizona State Sun Devils (13-5, 4-2) at No. 109 UCLA Bruins (10-8, 3-2), 11 p.m. (FS1)

Three bubble teams, yes, the Gaels are back in the hunt, face tricky road tests. Saint Mary’s can complete a season sweep of the Cougars, having won their meeting in Moraga by 22.

Thanks to the Pac-12’s scheduling system, this week features the only Arizona vs. L.A. matchups of the year.

76-160 at Top 75

Group 1 for the visitor only; Group 3 for the host

No. 99 Tulsa Golden Hurricane (12-7, 2-4) at No. 33 Cincinnati Bearcats (16-3, 5-1), 7 p.m. (ESPN2)
No. 89 Miami Hurricanes (9-8, 1-4) at No. 50 Syracuse Orange (13-5, 4-1), 8 p.m. (Raycom (regional)/ACCNE)
No. 87 Belmont Bruins (13-4, 4-2) at No. 44 Murray State Racers (15-2, 6-0), 9 p.m. (ESPNU)

While Cincinnati and Syracuse will look to defend their home floors from tricky, but ultimately beatable opponents, the lone meeting of the OVC’s top two squads in the NET rankings is set for the CFSB Center.

76-160 at 76-135

Group 2 for the visitor only; Group 3 for the host

No. 101 Texas State Bobcats (16-3, 5-1) at No. 110 Georgia State Panthers (14-5, 5-1), 7 p.m. (ESPN+ ($))
No. 105 Utah Utes (9-8, 3-2) at No. 116 Stanford Cardinal (9-9, 2-4), 9 p.m. (Pac-12 Networks)

While Utah-Stanford likely won’t have much impact on the Pac-12 race, tonight’s winner in Atlanta will have a significant leg up in the race for the top seed at the Sun Belt tournament. The Panthers already defeated the Bobcats by a 73-69 score in San Marcos back on January 5th.

161-353 at Top 75

Group 1 for the visitor only; Group 4 for the host

No. 320 Portland Pilots (7-13, 0-5) at No. 42 San Francisco Dons (16-3, 4-1), 10 p.m. (TheW.tv)
No. 197 Washington State Cougars (8-10, 1-4) at No. 70 Oregon State Beavers (11-6, 3-2), 11 p.m. (Pac-12 Network National/Washington/Oregon)

The Dons and Beavers will both look to avoid picking up potentially devastating Group 4 losses tonight.

Top 30 at 136-240

Group 1 for the host only; Group 3 for the visitor

No. 4 Gonzaga Bulldogs (18-2, 5-0) at No. 190 Santa Clara Broncos (11-9, 3-3), 11 p.m. (SWX Washington/Root Sports/AT&T SN Rocky Mtn./NBCS California/TheW.tv)

Gonzaga obliterated the Broncos, who have yet to lose a WCC game at home, 91-48 in Spokane on January 5th.

76-160 at 241-353

Group 3 for the host only; Group 4 for the visitor

No. 100 Colorado Buffaloes (10-7, 1-4) at No. 253 California Golden Bears (5-13, 0-6), 11 p.m. (Pac-12 Network Mountain/Bay Area)

There’s a reason this game is only on the Pac-12 Networks’ regional feeds, not the national one.

161-353 at 76-135

Group 2 for the visitor only; Group 4 for the host

No. 244 North Dakota State Bison (9-11, 3-3) at No. 119 South Dakota State Jackrabbits (15-6, 5-1), 8 p.m. (Midco SN/ESPN+ ($))

161-353 at 136-240

Group 3 for the visitor only; Group 4 for the host

No. 184 Omaha Mavericks (11-8, 5-1) at No. 239 Purdue Fort Wayne Mastodons (12-9, 4-2), 7:30 p.m. (PFW stream)

Given the Summit League Tournament’s format that gives the top two seeds a day off after their quarterfinals, tonight’s matchups have significant March seeding/rest/prep implications.
