The poor 1972 finish spilled over into the next year for Tolan, as was a disastrous year for him. Tolan's batting average plummeted to .206, he became a malcontent and had several squabbles with Reds management, who were still unhappy with his 1971 basketball injury. Tolan also went AWOL for two days in August and broke team rules by growing a beard. On September 27, the team suspended Tolan for the remainder of the season. The Reds won yet another division title but the suspension forced Tolan to miss the NLCS, which the Reds lost to the New York Mets. At the end of the season the Reds traded Tolan to the Padres for pitcher Clay Kirby. After the trade the Major League Baseball Players Association filed a grievance on Tolan's behalf. During the season, in which he batted .266 in 95 games, he learned that he had won his grievance. Tolan demanded that the Reds publicly apologize to him because his name had been slandered but never got the apology.
