Gregg Forwerck

When Gregg Forwerck arrives in Arizona in mid-February to begin photographing players on what he calls his "hit list," he affectionately refers to his time in Arizona's Cactus League as "my prison term in paradise."

For slightly more than a quarter of a century, since 1989, Forwerck has taken pictures for the Topps Chewing Gum Co. He is in his 15th season of shooting photos during Arizona's Cactus League, and overall, estimates that about 25,000 of his images have appeared on trading cards.
