The Pirates will promote right-hander Luis Ortiz, their No. 22 prospect according to Baseball America, this week for their series with the Reds, per source.
The Pirates and Reds have a scheduled doubleheader Tuesday, which is what Ortiz is being called up for.
Ortiz, 23, may not have the best numbers this season, but his pure stuff has been eye-opening and has sparked his jump from finishing last year in Class Low-A Bradenton to the majors this season. He works primarily off of a high-90s fastball and a slider which he can spin. FanGraphs' scouting report grades both pitches as plus.
