Upon his acquisition, Revering immediately assumed first base duties for the A's, batting .271 with sixteen home runs and 46 runs batted in his rookie season. The A's lost 108 games in 1979, however, Revering emerged as something of a star for the lowly club, hitting nineteen home runs and driving in 77 (both career highs) while batting .288. For his career in Oakland, he batted .279 with 52 home runs and 195 RBIs.
He assumed Spencer's job of backing up Bob Watson at first base. He batted .235 with two home runs and seven RBIs seeing limited action during the strike shortened season, however, he did make the post-season for the only time in his career. He made two appearances in the 1981 American League Division Series as a late inning defensive replacement, but did not have an at-bat.[5] He logged two at-bats in the 1981 American League Championship Series against the A's, collecting a single in the Yankees' 13-3 game two victory.[6] Though the Yankees reached the 1981 World Series, Revering did not make an appearance.[7]
1982-83
A month into the 1982 season, the Yankees dealt Revering to the Toronto Blue Jays, with minor leaguers Tom Dodd and Jeff Reynolds for John Mayberry.[8] In August, the Blue Jays offered Revering the choice of accepting a demotion to the minor leagues or his release; Revering picked the latter on August 2.[9] Shortly afterwards, he signed with the Seattle Mariners; however, he was released at the end of the season. Revering joined the Detroit Tigers for spring training1983,[10] but did not make the club. He was offered a minor league assignment, but chose to retire instead.[11]
