Castillo didn't factor into the decision in Friday's 7-3 win over the Pirates, giving up two runs on three hits and a walk over four innings while striking out five.

EDGE Analysis

He threw 60 of 89 pitches for strikes, and with the Reds keeping a very careful eye on his workload, manager Bryan Price elected to go to his bullpen for the fifth inning rather than give Castillo a shot at his third win of the season. The 24-year-old will take the mound Wednesday at home against the Brewers in what will be his final start of the year according to MLB.com -- "[Price] told me he didn't want me to throw, like, 100 pitches because I have one more outing after this one," Castillo said through an interpreter after the game -- but as yet the club hasn't indicated whether they'll shut him down completely or use him out of the bullpen for the rest of September.
