Nick Knight, cricket commentator and former England player was the guest of honour as the club hosted their first Minor Counties cricket game.
And the match, between Suffolk CCC and Bedfordshire CCC, came down to the final over, an exciting conclusion to the sunny day of celebration.
Knight, who raised the club’s flag and officially declared the building open in front of a crowd of members, said: “It’s a real honour to have been asked to open the new pavilion.
“My son plays at the club and he loves the game.
“So I spend as much time as I can at Woolpit Cricket Club, it’s such a friendly and happy place.
“And the new facilities will help boost the great cricket they already play.
“It’s all credit to the club to look to always improve and develop.
“Getting their first Minor Counties game is brilliant, it’s a big game so it’s a reward for the hard work the club have put in.”
Richard West, president of the Woolpit Cricket Club, said: “It was such a beautiful day — and a lovely speech and moment when the pavilion was officially opened.
“It’s what English cricket is all about, it’s just perfect.
“Getting our first Minor Counties match as well is recognition of the club and the hard work we’ve done to improve facilities to a level expected of our side.”
Work on the extension cost £152,000 and was finished for the start of the season.
The cost was met through £75,000 Lottery funding via Sport England, £25,000 from Mid Suffolk District Council, £12,000 from Section 106 community funding and £5,000 from Suffolk County Council.
The club also raised £15,000 and the remaining £20,000 was covered by an interest-free loan from the ECB.
