Davis was selected by the New York Mets in the third round of the 1976 Major League Baseball Draft. In, the Mets traded him to the St. Louis Cardinals and in he was drafted from the Cardinals by the Chicago Cubs in the Rule 5 draft. Davis made his major league debut on April 21, 1981 at the age of 24, and became the Cubs starting catcher as a rookie. In the earlier years of his career, Davis showed promise on offense and became a fan favorite among Cubs fans. In his second full season, 1983, he set what would turn out to be career highs with 151 games played, a batting average of.271 and 24 home runs. He also had 84 RBI in the same season. In 1984, he set a career high with 94 RBI and earned his first All-Star selection, as the Cubs won the National League Eastern Division title, their first title of any kind since. In the only post-season appearance of his career, Davis hit.389 with 2 doubles, 2 home runs, 6 RBI and an.833 slugging percentage in the 1984 National League Championship Series as the Cubs were defeated by the San Diego Padres in a five-game series. Later in his career, Davis improved on defense. During his great offensive seasons in 1983 and 1984, defense was somewhat of a challenge for him; in 1983 alone, he had 13 errors and 21 passed balls. However, by 1985 with the help of coach and former catcher, Johnny Oates, he had his defensive problems under control; his passed balls decreased, as did his errors. In 1986 he led National League catchers in putouts, assists and baserunners caught stealing and, finished second to Bob Brenly in fielding percentage. When Davis broke the 100 assists barrier in, he joined Johnny Bench, Jim Sundberg, Gary Carter and Tony Peña as the only catchers to have more than 100 assists in a season since the end of the Second World War. His defensive improvement resulted in his first and only Gold Glove Award and, earned him his second All-Star Game appearance. Around the same time, his offense started slipping. In 1986, he hit 21 home runs but struck out 110 times. His batting average slipped to.229 in 1988 and, he was replaced by rookie catcher Damon Berryhill, before being traded with three games left of the season to his hometown Atlanta Braves. He played only two games with the Braves that year, but he stayed in Atlanta for one full season and one partial season. With the Braves, he was also seeing occasional action as a first baseman. In 1989 he batted.169 with Atlanta in 78 games. In 1990, he played in 12 games, going 2-for-28 for a batting average of.071. He was granted a release by the Braves, after which time he signed a minor league contract with the Detroit Tigers organization. He played only 3 games for the Mud Hens before deciding to retire at the age of 33.
