CLAREMONT — Thirty-one years after a youth baseball tournament was established to honor Steve Corcoran, his children remain deeply grateful to the community for its strong support of the annual event that bears his name.

The Steven Corcoran Memorial Tournament, which concluded Tuesday evening at Monadnock Park, has become an enduring midsummer classic for Claremont, drawing teams from New Hampshire, Vermont and Massachusetts and raising money for youth baseball and softball.

Valerie Corcoran D’Aloia was 10 and her brother, Michael was 8, when their father, who coached youth baseball in Claremont, died of cancer at age 36 in 1993.

This year, 18 teams participated, nine in the 10-and-under division and nine more in the 12-and-under division.

At the championship games Tuesday, the Corcoran siblings said it has meant a lot to them to see so much support from the community to keep the tournament going in memory of their father.

“We are really honored it has gone as long as it has,” Michael Corcoran said. “The town has done a great job supporting it. Thirty-one years is a long time to have a tournament run and, yes, we are proud as can be. It is a great way to keep his memory alive.”

The tournament raises money for the Claremont Youth Baseball and Softball Association. This year about $10,000 will be raised, said Raquel Fluette, a member of the CYBSA board. The money supports youth baseball and softball with purchases of equipment, including bases, bats and balls.

The tournament also emphasizes sportsmanship. After each game, the opposing coach chooses a player from the other team for the game’s sportsmanship award. The siblings said their father believed strongly in being competitive on the field, and he equally valued good sportsmanship.

“It was a big thing for my dad,” D’Aloia said, while working in the concession booth despite having the use of just one arm with the other heavily bandaged from recent surgery.

Though Michael Corcoran said he was not sure how the idea of a tournament began, he knew there was a lot of camaraderie among the coaches some three decades ago and they were all friends.

“I’m just glad they started it,” Corcoran said. “I enjoyed it back then when I played, and I enjoy it today. I talk to other families throughout the years with kids on teams in other towns and they look forward to it every year.”

The tournament has steadily grown in popularity, and this year about 230 players participated.

“It is not difficult to attract teams,” D’Aloia said. “We have a lot of repeat teams. Some can make it, some can’t, so they rotate.”

The 12U Hartford team has played in the tournament the last few years, Hartford coach Joe James said before the start of the championship game against Connecticut Valley, whose players are mostly from Walpole, N.H.

“This is a fun tournament,” James said. “And there is great competition and great sportsmanship.”

Michael Costa coaches Norwich Youth Baseball, and his 10U team made its third trip to the tournament this year.

“It is high-quality baseball that is close by,” Costa said about why they play. “But also it is a labor of love, and I just love the way it connects families, communities and generations.”

The siblings commended the association’s work in putting together the tournament and a lot of volunteers pitch in as well.

“They have done a great job, and hopefully that can continue it,” Michael Corcoran said. “We thank the families, the coaches, everybody behind the scenes who put in volunteer hours. It is a real town event, and a lot of people come out and help.”

As she served up another meal at the concession booth, D’Aloia had a hard time putting into words what the tournament has meant to the family.

“It is remarkable. Just remarkable the way the community has come around for 31 years,” D’Aloia said. “It leaves me speechless.”
