The Rays optioned Solesky to Triple-A Durham on Friday, Ryan Bass of Rays.tv reports.
Solesky was called up for his first taste of the majors this week and will return to Durham without making his big-league debut. The 28-year-old remains on the 40-man roster, but that may not last long given his 6.57 ERA and 1.74 WHIP across 24.2 innings at Triple-A this year.
