JUPITER, Fla. (AP) — A lucky fan was about to win a truck, and Adam Wainwright thought it was pretty cool. Until the St. Louis Cardinals pitcher realized it was his white pickup. Cardinals teammates Lance Berkman and Skip Schumaker pulled off an April Fools’ Day prank Sunday that had Wainwright hoping at first that it was all just for laughs. “As long as that’s a joke, that is well done,” Wainwright said. “I don’t know if that’s a joke, yet.” Turned out, it sure was. Following the second inning of the Cardinals’ 2-1 spring training loss to the Washington Nationals, public address announcer John Frost read a fake script proclaiming that a fan won a car. Berkman drove it onto the field, and Wainwright quickly realized it was a prank aimed at him.
