The club also announced that outfielder Michael Hermosillo has been reinstated from the 60-day IL. That move absorbs the newly opened 40-man spot. Hermosillo was optioned to Triple-A.
The 26-year-old Curtiss did not get into a game in his second stint of the year on the MLB roster; he made just one appearance earlier in the season. In 21 1/3 innings this year at Triple-A, Curtiss has allowed 14 earned runs on twenty hits with a 29:13 K/BB ratio.
