Bobby Winkles of Arizona State suggested that Palmer get more experience playing collegiate summer baseball, so Palmer went to South Dakota to join the Winner Pheasants of the Basin League. The team advanced all the way to the league finals, and Palmer caught the attention of Baltimore Orioles scout Harry Dalton while pitching in the second game of the championship. According to Palmer, 13 Major League Baseball (MLB) teams recruited him after the season wrapped up, but Jim Russo (the scout who also signed Dave McNally and Boog Powell) and Jim Wilson of the Orioles made the best impression on his parents with their polite manners. Palmer signed with Baltimore for $50,000.
