A baseball tournament honoring a police officer from Long Island killed in the line of duty has more than doubled in size, organizers said Saturday.

The second annual Brian Moore Memorial Tournament fundraiser being held this weekend at fields around Nassau County boasts 75 teams — up from 35 last year.

“It’s real exciting,” said Ralph Raymond, 53, of Plainedge, who helps run a memorial fund established in Moore’s name.

Raymond credited widespread community support for the rapid growth of the tournament, which has teams coming from as far away as Connecticut.

“It’s just been an overwhelming show of support toward Brian Moore . . . and his whole family,” he said.

All proceeds go to the memorial fund, which provides assistance to families of firefighters, police and military personnel. The fund, which held $35,000 as of last month, awarded its first two $5,000 scholarships to Plainedge High School graduates in June.

Moore, 25, of Plainedge, was fatally shot while on patrol as an NYPD officer in Queens Village in May 2015. He was posthumously promoted to detective.

Raymond, who coached Moore for years in the Plainedge Youth Baseball League, remembered Moore as a young man with an “infectious smile” who was “always happy.”

“We’re committed to honoring Brian’s memory. Brian represented everything good about this community,” Raymond said.

Moore’s father, Raymond, threw the ceremonial opening pitch for the tournament. The competition, which began Friday, concludes with a championship game Sunday night at Allen Park in Farmingdale.
