Colan Miller waited his whole career for Camden Catholic to push into South Jersey baseball prominence.

Maybe that's why the senior righthander worked so quickly and efficiently in Saturday's Diamond Classic quarterfinals.

Miller pitched a three-hitter with five strikeouts as Camden Catholic beat Pitman, 2-1, in a game that took just 74 minutes at Washington Township.

"The tempo was perfect for me," Miller said. "I love to work fast."

With the victory, Camden Catholic (16-8) advances to face Bishop Eustace in Sunday's semifinals at Washington Township at 1 p.m. The finals are set for 5 p.m. Sunday at Eastern.

Camden Catholic won the first Diamond Classic in 1974. That was the Irish's only title in the history of the tournament.

"We haven't been there in a while, and for us to get there now, it's a really big deal for us," Miller said.

Miller and Pitman senior righthander Chris Seibert both worked fast and threw strikes.

Seibert struck out 10 and allowed six hits. Only one of Camden Catholic's runs was earned.

"It was pretty intense," Seibert said of the fast-paced game. "It was a great experience."

Camden Catholic took a 1-0 lead in the top of the third as Shawn Stone reached on an infield error, advanced on a passed ball, and scored on a throwing error on a sacrifice.

Pitman (15-5) tied the game in the fourth. Trevor Datz singled, advanced on a groundout, and scored on a two-out single by Clay Enzman.

Camden Catholic took the lead in the seventh after Miller beat out an infield single by the closest of margins. Courtesy runner Ryan Ziegler advanced on Stone's sacrifice and scored on Albert Faiola's two-out single to center field.

"I was waiting for a slider," Faiola said. "It's awesome for us to get this far" in the Diamond Classic.

Miller said he threw "seven or eight" fastballs in the game. He relied mostly on his curveball and splitter. He faced just 24 batters and didn't issue a walk.

"He's been our guy for two years," Irish coach Bob Bergholtz said. "He wants the ball in these situations. He lives for this moment."
