The MHSAA Boys Basketball Tournament finished up its first week Friday with many of the expected contenders moving on – but quite a few surprises as well. 

See below for four teams from each class that jumped out from Districts, with Regionals tipping off tonight. Click for brackets for all 32 and stay with Score Center tonight for scores and updated matchups.

Class A

Belleville (19-4) – The Tigers have won eight games straight and improved seven wins from a year ago, and had an eventful District week. In the Semifinal, Belleville beat Romulus, the team with which it shared the Western Wayne Athletic Conference Blue title, and then downed Westland John Glenn in overtime in the Final.

Detroit Western International (17-3) – The reigning Class A champion has had a solid season, finishing second in the Detroit Public School League West Division 1. But the biggest highlights came last week with a 77-76 overtime win over PSL Tournament champion Detroit East English, followed by a 15-point District Final win over 14-win Martin Luther King. 
 
Lowell (18-5) – Since winning three games in 2010-11, the Red Arrows have improved their win total every season of the last five and are four victories better than a season ago. Lowell added a couple top teams from the east side of the state to the schedule this winter and lost locally only to Grand Rapids Christian twice and Wyoming Godwin Heights. 
 
Roseville (17-5) – The Panthers improved to five wins better than a season ago, adding a District title to a runner-up finish in the Macomb Area Conference White. They've won 10 of their last 12 games. 

Class B

Ann Arbor Gabriel Richard (12-11) – The Fighting Irish entered the tournament two games below .500 but emerged on the plus side thanks in part to a 43-41 upset of Chelsea in the District Final. Chelsea finished 16-6.

Detroit Osborn (13-10) – The Knights again proved the tough competition in the Public School League is a good primer for the postseason, winning their second straight District title despite finishing fifth in the PSL East Division 1 standings and going 2-7 in January. 
 
Flint Northwestern (12-11) – The Wildcats finished only fifth in the Saginaw Valley League South but have won five straight and avenged last season’s District loss, downing Frankenmuth 57-52 in this year’s Final. Frankenmuth finished 20-3.
 
Stockbridge (17-5) – The Panthers split with Leslie during the regular season but still finished a game behind the Blackhawks and second in the final Greater Lansing Activities Conference standings. But Stockbridge beat Leslie (20-3) in the District Final. 

Class C

Beaverton (19-1) – Bad weather kept Beaverton from getting in its full 20 regular-season games, but the Beavers did manage to extend their Jack Pine Conference winning streak to 34 with a second straight league title. They beat two league foes to win the District as well. 

Constantine (14-9) – The Falcons dropped their final two regular-season games and finished only fourth in the Southwestern Athletic Conference Valley. But they beat third-place Schoolcraft on the way to a second-straight District title and after losing to the Eagles only four days before.
 
Grandville Calvin Christian (17-4) – The Squires took a couple of late losses prepping for the postseason with a final run that included reigning Class C runner-up NorthPointe Christian, reigning Class B champion Godwin Heights, plus 17-win Allendale and 15-win Covenant Christian. But those challenges paid off as Calvin Christian downed Covenant Christian 64-50 to start last week and then NorthPointe 52-45 in the District Final. 
 
Ishpeming Westwood (10-12) – The final two weeks of the regular season included four losses over its final five games, but Westwood was a different team once the District began. The Patriots started with a win over Manistique – which they had lost to Feb. 17 – and finished with a 51-47 win over rival Ishpeming after falling to the 16-win Hematites twice in league play. 

Class D

AuGres-Sims (11-9) – The Wolverines were another team that entered the postseason on a bit of a stumble, having lost four of six after locking down second place in the North Star League Little Dipper division. But they beat champion Fairview by 12 to open last week and then Mio 62-59 in the Final.
 
Fulton (16-6) – A five-point loss to Class C Lakeview in the regular-season finale is the only blemish for the Pirates over their last eight games. They clinched the District title with a 55-42 win over league rival and 13-win Fowler. 
 
Novi Franklin Road Christian (16-6) – Annual contender Southfield Christian is the team most pay attention to from the Michigan Independent Athletic Conference, either division. But Blue runner-up Franklin Road Christian has won eight of nine to continue a seven-win improvement from a season ago. 
 
Rock Mid-Peninsula (13-9) – The Wolverines won only three games each of the last two seasons, but added a District title to this winter of improvement to go with the Skyline Central Conference East championship.
