Gonzaga has won 12 straight games and hasn't lost since Jan. 19 at Butler. The Zags' reward? The No. 1 spot in ESPN.com's Power Rankings.

Newcomers to this week's rankings are Oregon (No. 21) and UCLA (No. 23).

Editor's note: Team comments written by Robbi Pickeral.

1. Gonzaga
The Zags have never been ranked No. 1 -- until now. But then again, no WCC team has ever gone 16-0 -- until now. Their conference schedule isn't as difficult as some, but the Zags have won 12 in a row to clinch the regular-season crown.

2. Indiana
Can anyone ever really feel settled when ranked No. 1 this season? Certainly not the Hoosiers, who dropped their third game of the season while topping the rankings -- this time to Trevor Mbakwe and Minnesota. Indiana bounced back against Iowa and has won five of its past six.

3. Duke
Welcome back, Ryan Kelly. The senior forward returned a bit quicker than expected after missing two months with a foot injury. He scored a career-high 36 points Saturday to propel his team past Miami. Not only was it a huge bounce-back win after a midweek loss at Virginia, but a fast return to form that made the Devils the nation's top team before his injury.

4. Kansas
The Jayhawks rolled to their sixth straight, as the latest memorable moment came when Ben McLemore broke Danny Manning's freshman school record by scoring 36 points against West Virginia. That's the second time during this winning streak the guard has scored at least 30.

5. Georgetown
Add Rutgers coach Mike Rice to the list of Otto Porter Jr. admirers after the Hoyas won their 11th straight: "It's not even close who is the Big East Player of the Year right now," Rice told the AP. "And to be honest with you, if he keeps continuing this, it's not even close [for] national player of the year."

6. Louisville
Luke Hancock, who hit a key 3 with 51 seconds left to beat Syracuse, said the game had an NCAA-like atmosphere -- giving the Cardinals, who've won five in a row, another confidence boost. The win kept Louisville tied for second place in the Big East standings.

7. Miami (FL)
The only bad part of an instant classic is that someone has to be the loser. Against Duke on Saturday, the Hurricanes missed two game-tying 3s in the final seconds -- dropping their second game in three outings as a result.

8. Michigan
Yep, Trey Burke's good. He came up big -- eight assists and 21 points, including a steal and dunk with 22 seconds left -- to push the Wolverines past Michigan State on Sunday. It was a key victory for Michigan, which gave Penn State its first Big Ten win of the season earlier in the week.

9. Florida
The Gators clinched at least a share of the regular-season SEC title, but coach Billy Donovan wasn't pleased with his team's sloppy play in a win over Alabama -- especially after an early-week loss at Tennessee. Will Yeguete and Michael Frazier II returned from injuries but still aren't quite back to form.

10. Michigan St
It's been a rough slate for the Spartans of late, losing by four to top-ranked Indiana, then by eight at No. 18 Ohio State, and then by one at Michigan on Sunday. And it doesn't get much easier. Next up is Wisconsin.

11. Kansas St
Guard Rodney McGruder's 3-pointer at the buzzer on Saturday night secured the Wildcats' win over Baylor and kept them tied with Kansas for the Big 12 lead. Kansas State has now won five straight, and nine of its past 10.

12. New Mexico
The Lobos secured their fifth straight conference championship in the past six seasons with Saturday's win over Wyoming. They also finished with a perfect league record at home (their last two regular-season games are on the road) and extended their winning streak to five with solid defense, holding SDSU to 36.2 percent shooting and Wyoming to 28.1 percent from the field.

13. Oklahoma St
Markel Brown rated his two-handed breakaway windmill in the first half against Texas -- the one that gave the Cowboys their first lead in the eventual win -- as his favorite jam as of now. It's going to be interesting to see what he comes up with next. OSU has won 10 of 11.

14. Ohio St
Lenzelle Smith Jr.'s season-high 24 points led the Buckeyes to a win over Northwestern. It marked the first time in four games he's scored in double figures for OSU, which is now in a four-way tie for second place in the Big Ten.

15. Marquette
Marquette extended its home winning streak to 25 straight with wins over No. 12 Syracuse and No. 21 Notre Dame. The Golden Eagles have won four of five overall, including victories over three ranked teams.

16. Saint Louis
The Billikens extended their winning streak to 11 by beating St. Joe's and George Washington last week, led by Dwayne Evans, who averaged 21.5 points. Interim coach Jim Crews' crew now has a one-game cushion on VCU in the Atlantic 10.

17. Syracuse
The Orange have lost three straight games, all to ranked teams, and six of their past 10 overall, since starting the season 18-1. But coach Jim Boeheim, according to The Post-Standard, likes what his team can be: "We haven't shot very good and we could've won two of the three. If we were getting beat by 15 or 20 points, I'd be worried. I'd be very worried. But we're right there."

18. Pittsburgh
Averaging only seven points in Big East play, Talib Zanna came up big for the Panthers in a win against Villanova. He scored nine of his 14 points in overtime, plus had a career-high 19 rebounds to secure Pitt's third straight win.

19. VCU
The last time a team had 15 steals against Butler? Jan. 13, 2000. That is, until Saturday, when the Rams had swiped 14 by halftime alone. VCU's 84-52 blowout marked its seventh win in its past eight games. It trails Saint Louis (the only loss during that run) by one game in the Atlantic 10 standings.

20. Wisconsin
Purdue halted the Badgers three-game winning streak by beating them at their own game -- namely defense and hustle plays. It marked the first time in coach Bo Ryan's 12-year tenure that the Badgers lost on Senior Day, and although they haven't been eliminated from winning the Big Ten title, it's going to be tough.

21. Oregon
The Ducks welcomed back guard Dominic Artis during Thursday's victory over Oregon State, only to suffer another injury when second-leading scorer Damyean Dotson injured his hip. Oregon is hoping to have him back for its final two regular-season road games -- at Colorado and at Utah.

22. Arizona
The Wildcats had two rough outings in Los Angeles, falling to both USC and UCLA and dropping to fourth place in the Pac-12 standings. Arizona's regular-season finale is March 9 against Arizona State.

23. UCLA
The Bruins' win over No. 11 Arizona marked their fourth straight victory -- and pushed them into a tie for first place in the Pac-12 standings. Freshman Shabazz Muhammad has averaged 18.8 points during this steak. UCLA will finish the regular season on the road against Washington State and Washington.

24. Memphis
The Tigers had their 18-game winning streak halted by Xavier, but bounced back against Central Florida to remain undefeated in Conference USA. The win also marked the team's eighth C-USA title.

25. Notre Dame
An illness limited leading scorer Jack Cooley to just 15 minutes in the loss to Marquette. The virus had kept him out of practice for two days, but he managed only one rebound and was 0-for-1 from the field. He had scored in double figures in eight previous games.
