Bowman Field went dark again in 1963 but came back strong in 1964 with the addition of the New York Mets franchise. The Mets would sign a 4 year PDC with Williamsport and donate the lighting from the Polo Grounds to Bowman Field (which they just left in favor of new Shea Stadium). Their inaugural season featured Ron Swoboda (21 2B, 14 HR, .276). Jerry Koosman would appear in 2 games in 1965 and Nolan Ryan would pitch from this mound in 1966, striking out 35 in 19 innings. Finally Jon Matlack would pitch 2 games in 1967. The Williamsport Mets finished in 4th place in 3 times and 5th once.
