Mighty Warriors, Spartans, Blue Streaks and Patriots and other teams around the region are back in the field and at the plate. In 1990 and 1991, young men and women acquitted themselves with honor. Softball pitchers Shane Kozak of Schenectady and Chris Nally of Columbia were throwing missiles. Steve Pelosi was stealing bases for Johnstown. Todd Lucca was knocking out hits for Mohonasen. It’s time to “Play ball!” once again. Local players are back on the same fields used by their baseball and softball ancestors 20 years ago. They’re swinging, slinging, striding and sliding just as hard as the “kids” — now in their mid- to late 30s — did during glory days of the past.
