Undefeated Calais and defending state champion Central Aroostook of Mars Hill carry the Eastern Maine banner into Saturday’s Class C and Class D boys basketball state finals at the Augusta Civic Center.

Central Aroostook (20-1) will face 17-3 Richmond for the Class D title at 3:05 p.m., following the girls final between Woodland and Valley of Bingham.

Calais (21-0) will square off against 18-3 Winthrop for the Class C boys crown at 9:05 p.m., after the girls final between Dexter and Hall-Dale of Farmingdale.

Central Aroostook (20-1) brings a 20-game winning streak into its quest for a second straight gold ball, and has won seven straight tournament games – all at the Bangor Auditorium.

Coach Tim Brewer’s sixth-ranked Panthers cruised through the Eastern Maine tourney, rallying from a two-point halftime deficit in its quarterfinal to defeat No. 3 Bangor Christian and then besting No. 2 Schenck of East Millinocket and top-ranked Deer Isle-Stonington to earn its trip to Augusta.

Central Aroostook is led by two-time Eastern D tournament MVP Andrew York, a 6-2 senior guard who averaged 18.3 ppg in this year’s regional, 6-0 junior forward Tim Carlson, who also averaged 18.3 ppg, and 5-11 senior forward Taylor McLaughlin, a key defensive weapon.

Richmond is seeking its first state title since 1986 after ending Valley’s eight-year hold on the Western D crown by upending the Cavaliers 56-49 in last Saturday’s regional final.

Coach Paul Lancaster’s Bobcats have four sophomores and six juniors on the roster, with 6-1 guard Billy Milne the lone senior starter.

The Bobcats feature 3-point shooting, having made 18 in a game against Forest Hills of Jackman and 10 – of their 17 total field goals – in their tourney win over Valley.

Milne, 6-0 sophomore Brandon Lancaster and 6-0 junior Glendon Kendrick are among the team’s 3-point shooting threats, while 6-foot-10 sophomore Marc Zaharchuk and 6-4 sophomore Sam Carter provide a tall inside presence for the Bobcats, who are riding a 10-game win streak.

Calais entered the weekend as one of two undefeated boys basketball teams in the state, along with Class B Mountain Valley of Rumford.

The Blue Devils anticipate an up-tempo challenge from Winthrop in their quest for the program’s first state title.

Coach Ed Leeman’s club features a balanced offense and defense led by 6-1 juniors Brandon Tomah – the Eastern C tourney MVP – and Chris Taylor, and also featuring seniors Adam Knowles and Mike Guthrie, junior Robbie Rogers, sophomore Sam Bell and 6-3 freshman Cal Shorey.

The top-seeded Blue Devils had little trouble in their regional, their closest game a 71-57 semifinal victory over No. 4 Madawaska. Calais topped Penquis of Milo by 27 points in the quarterfinals and bested No. 2 George Stevens Academy of Blue Hill 67-44 in the final.

Calais last appeared in a state final in 2002, losing a last-second 48-47 decision to Jay at the Augusta Civic Center.

Winthrop last reached the state championship game a year later when it fell to George Stevens Academy 66-58. The Ramblers are seeking their first gold ball since 1993.

The Ramblers feature 6-3 senior forward Tyler Smithgall, MVP of the Western C tournament after averaging 21.3 points in three games. That effort was highlighted by a 33-point performance in the semifinals, when Winthrop outlasted Dirigo of Dixfield 67-64 in double overtime on a buzzer-beating 3-pointer by 6-1 sophomore Mike Gingras.

The second-ranked Ramblers edged No. 1 Boothbay 57-54 in the final to avenge a regular-season loss to the Seahawks.

Other key players for second-year coach Dennis Dacus’ club include 5-10 sophomore point guard Sam Leclerc, 5-10 junior Nate Damm and 6-1 sophomore Tim Gingras.
