The Pirates announced that they have designated right-hander Wilfredo Boscan for assignment. The move was necessitated by the fact that the Indians’ waiver claim of Deolis Guerra had to be rescinded due to inflammation in Guerra’s left knee. As such, Guerra will remain with the Pirates and be placed on the 15-day disabled list. That pushed Pittsburgh’s 40-man roster up to 41, and Boscan will be the odd man out.
Boscan, 25, hasn’t pitched for the Pirates in 2015 and in fact has never thrown a pitch in the big leagues despite being promoted to the Major League roster on three separate occasions this season.
