A veteran minor leaguer, "Hy" Vandenberg has finally made the major league grade. Vandenberg had nine seasons of minor league experience. He started in a Class B league with Bloomington and thereafter pitcher with Minneapolis, Williamsport, Chattanooga, Syracuse, Baltimore, and Jersey City, all A or AA clubs. The Giants obtained him from Baltimore in 1937, but optioned him out. Last year, he won 15 games for Jersey City, and had an earned-run average of 2.72. He was highly impressive at the Giant training camp this Spring, and showed enough stuff in action to earn himself a berth on the Giant mound staff.
