The Twins optioned Gonzalez to Triple-A St. Paul on Thursday.
With Austin Martin (hamstring) returning from the injured list Thursday, Gonzalez will end up as the odd man out of a spot on the Twins' 28-man roster. The 22-year-old went 2-for-8 with two walks while appearing in seven games for the Twins, and he'll likely play out the rest of the season at St. Paul, barring an injury to another one of Minnesota's outfielders.
