Natalie Klinker blocked Sophia Stiles shot attempt at the buzzer to preserve the Eagles' 34-33 win for the Class B state girls title Saturday night at Rimrock Auto Arena.
It was the 11th straight year that Fairfield or Malta won the state title. It is the Eagles seventh state championship since 2007.
The M'ettes were the defending state champions.
Trailing 22-14 at halftime, Fairfield outscored Malta 11-3 in the third quarter.
Allix Goldhahn led the Eagles with 17 points. The Idaho-bound Klinker finished with 13 rebounds.
Stiles, headed to the University of Montana, scored a game-high 22 points.
After shooting 21 percent from the field in the first half, Fairfield made 50 percent of their shots in the second.
Malta shot just 16 percent (3 of 19) from the field in the second half.
Three Forks 63, Red Lodge 56
The Three Forks Wolves claimed third place at the Class B girls state basketball tournament, beating the Red Lodge Rams 63-56 Saturday afternoon at Rimrock Auto Arena.
Kyle Olson scored 29 points to pace the Wolves, who took an 11-point lead into the second quarter and maintained it most of the way. Red Lodge got to within four on a Kylie Kelly 3-pointer late in the game, but Three Forks didn't buckle.
Shainy Mack added 15 points and Josee Scott 11 for the Wolves, who finished the year 22-5.
"It's been an unbelievable ride for the last month," Three Forks coach Mike Sauvageau said. "The whole year has been really, really fun. The last 3 1/2 weeks, we've beaten a lot of quality teams right down to the wire."
Sauvageau praised the Rams for keeping coming at his team. The Rams (20-8) were led by Natalie Hilderman's 26 points. Kelly finished with 14.
Red Lodge advanced to state by taking third place in the 4B District tournament and third pace at the Southern B Divisional. One more third place wasn't to be.
"We were 6-0 in (elimination games) until that one right there, and I don't know if you count that as an elimination game or not," Red Lodge coach Jason Reimer said. "These girls have nothing to hang their heads about. It's been a great season for us."
Red Lodge edged Florence-Carlton 47-42 earlier in the day for the chance at the third-place trophy. Natalie Hilderman scored 16 points to lead the Rams, and Danielle Zahn finished with 15 for the Falcons (17-10).
Three Forks topped Wolf Point 59-44 behind 23 points from Shainy Mack. Ashtyn Hentges had 12 points to lead Wolf Point (19-8).
