The Rays designated Solesky for assignment Monday.
Solesky ended up losing his spot on the 40-man roster after the Rays needed to clear room for trade-deadline pickup Tyler Wells. The 28-year-old righty made a three-inning relief appearance in his MLB debut for the Rays back in May but has pitched exclusively at Triple-A Durham ever since. Over 24 appearances (seven starts) at Durham, Solesky owns a 7.03 ERA, 1.71 WHIP and 54:22 K:BB in 56.1 innings.
