GORHAM — It’s Friday night and the courts at the corner of Acorn Street and Gray Road buzz with activity.

Seven men and five women are split into three groups of four, each playing doubles pickleball inside a chainlink fence that once housed a single tennis court. It’s an upbeat group and an upbeat game, played amid a cacophony of perforated plastic balls being thwacked by composite paddles.

“Pickleball is a crazy game right now,” said Cindy Hazelton, Gorham’s recreation director. “It’s had a huge surge in popularity.”

But not everyone is thrilled about the game’s growing popularity. In some communities, tennis players are finding they have to compete with pickleball players for space on local courts.

Hazelton oversaw the installation last week of six permanent pickleball net posts at the town’s Little Falls Activity Center. They are the second Maine courts devoted exclusively to pickleball after Sanford created three courts in 2014.

A short walk down the road from the Gorham courts, at the Little Falls Recreation Area, two tennis courts have freshly-painted red lines for pickleball.

Gorham will host the Maine Senior Games pickleball tournaments Saturday (men’s and women’s doubles) and Sunday (singles and mixed doubles) with more than 100 participants. Last year’s Senior Games pickleball event, which took place indoors at the South Portland Recreation Center, drew 119 players, up from 73 in 2013.

By contrast, the Senior Games tennis tournament fell from 53 players three years ago to 17 in 2013 and 16 last year. Only a handful have registered for this year’s event, scheduled for early September.

“We’re a month away, so it’s still early,” said Jo Dill, who directs the Games through the Southern Maine Agency on Aging. “People are playing tennis, but I think more people are playing pickleball. The court’s smaller and there’s a lot of net playing. A couple of people say my knees don’t take to tennis anymore but I can still play pickleball.”

To some of those who remain devoted to tennis, pickleball is an invasive species taking over prime recreational real estate. Already this year, pickleball lines have gone down on tennis courts in Bath, York and Cape Elizabeth. Tennis courts in Scarborough and Portland got similar treatment last year.

“When they put the (pickleball) lines on, it was a little disconcerting,” said Paul Robinson of Cape Elizabeth, warming up for a tennis match Friday morning on one of two pond-side courts inside Fort Williams Park.

His wife and doubles partner, Karen Robinson, said noise from pickleball matches – both from the plastic ball and the usually vocal and enthusiastic players – can be distracting to those playing tennis.

“There’s a constant ping-ping-ping from the paddles,” she said. “The sound effects do not make for a conducive atmosphere.”

Indeed, said Dorothy Stack, another Cape Elizabeth resident who has played tennis regularly at Fort Williams for 20 years and last month found herself alongside two games of pickleball on the adjacent tennis court.

“It wasn’t enjoyable,” she said. “Pickleball is loud and fun and social. Tennis is a bit quieter game. Tennis has four people who might chat between points or say, ‘Nice shot.’ Pickleball has four people on each side and then there’s all these extra people on the side who have set up chairs and are waiting to play. There’s a lot of movement, in and out. It’s too much.”

At age 59, Stack said she understands she’s approaching the pickleball demographic. It looks like fun and she may join others, like Paul Robinson, who wield both a racquet and a paddle.

But not yet.

Roger Rioux, 67, of Cape Elizabeth went to the Fort Williams Advisory Commission in May for permission to paint pickleball lines on the two tennis courts (there’s also an upper tennis court in a different, narrower enclosure that includes a basketball court) inside the 90-acre park. On Tuesday and Thursday mornings, Rioux puts up four portable nets for pickleball.

“We chose Tuesdays and Thursdays because typically there aren’t tennis players here,” Rioux said Thursday morning while waiting for players to arrive. “The problem is that everyone wants to play from 8 to 9:30 because it’s the cooler part of the day.”

Six more tennis courts at the high school are reserved for children’s recreation programs, but Rioux wonders if one or two could be reserved for adult use on the mornings his group plays pickleball at Fort Williams.

“We do this at our own expense,” Rioux said. “I bought three nets. We paid for the paint. One guy is lending us the fourth net. … Look what we’re doing for seniors, and it costs the town absolutely nothing. This is zero impact in terms of financials for the town.”

Can tennis and pickleball coexist? Bob Malley, director of public works in Cape Elizabeth for three decades, thinks they can. He’s heard from both Stack and Rioux, and has installed comment cards and a suggestion box at the tennis courts to gauge interest and activity.

“There’s this tremendous interest in pickleball, which everybody recognizes,” Malley said. “But how can we best share the facilities?”

Stack said she thinks the answer is dedicated courts for each sport. So far, that seems to work in Gorham. At Deering High in Portland, lines for four pickleball courts were painted around the main tennis court, with other tennis courts separated by fencing.

“I think every community is going to have to deal with this up-and-coming sport,” Malley said. “I’ve learned a lot in the last year.”
