Somebody forgot to tell the New England Region champions.

Scotty Dettmer’s RBI single tied the game and a second run scored on an error as Stamford beat Centennial, Colorado 2-1 in the Babe Ruth 13-year-old World Series quarterfinals at Diethrick Park.

“I’m a high school coach. … It just does not get better than that,” Stamford head coach Michael Riveles said. “Seeing my kids going nuts in the dugout like this, this is what it’s about. I’m speechless.”

The win sends the National Division’s No. 2 seed into today’s 4:30 p.m. semifinal against American Division No. 1 seed Eagle Pass, Texas.

“They are a fantastic team,” Riveles said of Eagle Pass. “Our goal was to get here and win a game. After that we wanted to get into bracket play and hopefully steal a win. We’ve been on the gravy train since late July.”

Centennial took a 1-0 lead in the top of the seventh inning when Kian Trebelhorn led off with a single, stole second on a pickoff attempt, went to third on a groundout and scored on Max Comeaux’s clean RBI single through the right side of Stamford’s infield.

“Tonight, we talked about staying up every pitch and showing that we belong here,” Riveles said. “We fought. I’m super proud of them.”

Trailing for the first time all night, Stamford immediately went to work on the bottom of the frame. First, No. 7 hitter Dylan Riveles led off with a single.

“That was my son. He’s little. He’s been hitting the ball hard, but right at people,” Coach Riveles said. “He got on the board and started it, and then the bottom of the order executed.”

Brandon Jones then faked a bunt attempt as Riveles took second on a wild pitch.

“It was a fake bunt and steal to move him on,” Riveles said.

Jones then laid down a perfect sacrifice bunt to move Riveles to third before Ryder Palange walked.

“Sometimes it works, sometimes it doesn’t,” Riveles said of the bunt. “Tonight was our night.”

With runners at first and third, Centennial brought its infield in before Palange stole second.

“The infield in worked great for us because we have kids who can’t really drive it,” Riveles said. “That was as good of a game as you can see.”

Dettmer followed with a bloop single to center field that scored Riveles. Centennial’s center fielder then tried to throw Palange out going to third and when the throw got away, Palange raced home with the winning run.

“He’s a young kid. He’s got some stones,” Riveles said of Dettmer. “He went up there unafraid and executed.”

For the first six innings, Thursday’s matchup was a pitchers’ duel between Stamford’s Cody Meek and Centennial’s Mason Mayer — both of whom were named their respective teams’ Ron Tellefsen Player of the Game.

Mayer, the Centennial right-hander, tossed six innings of shutout ball, allowing five hits and three walks — one intentional — while striking out three. His third strikeout of the night came on his 95th pitch and ended the bottom of the sixth inning with Stamford leaving the bases loaded.

Meek did one inning better, tossing seven innings of one-run ball, allowing four hits and no walks while striking out eight. He needed just 88 pitches to get through the game.

Meek faced the minimum through five innings, helped by a pair of pickoffs. Centennial then stranded a runner at first in the sixth inning.

“Cody was awesome. He has just gotten better and better,” Riveles said. “He doesn’t show emotion, he just delivers. Cody is our guy. He did what we asked of him.”

Stamford stranded five runners through the first four innings before leaving the bases loaded in the sixth.

Jace Bosone led off with a single, stole second, went to third on a groundout and beat a throw to the plate on Austin Leonard’s RBI fielder’s choice.
