After three seasons with the Rockies, Ramage was traded to the St. Louis Blues in exchange for a first-round draft pick. With the Blues, Ramage developed into a steady and skilled defenseman. During the 1985–86 season, Ramage's fourth with the Blues, he posted a career-best 66 points (which was a Blues team record for points by a defenseman). He added 11 more in 19 playoff games as St. Louis made the Stanley Cup semi-finals, losing to the Calgary Flames in seven games.
