Workers last week extended upwards the netting around a newly turfed little league baseball field at Mead Park, days after two foul balls went sailing into the lot behind it and crashed into the windshields of cars parked there. The backstop at Mellick Field was shifted back as part of a public-private project that also saw the infields of both Mellick and Gamble Fields turfed for the start of this season, officials said. It used to be that part of the backstop at Mellick jutted over home plate so that some pop ups hit it and bounced down, Recreation Director Steve Benko said when asked about the need to make the netting higher. But the architects of the project, partly because potential outs were taken away by that configuration, decided to move the backstop, Benko said. “What happened was the whole angle changed, we had foul balls that used to hit the fence or trees, so they had New Canaan Baseball raise the netting to try and stop the problem,” Benko said.
