Castillo (3-7) earned the win over the Brewers on Wednesday, allowing one run on four hits over eight innings. He struck out 10 and did not issue a walk.
Castillo acknowledged last week that this would be his final start of 2017, and what a way to go out. After allowing a solo homer to Neil Walker in the first, Castillo breezed through the rest of the afternoon, allowing two hits over his final seven frames. The 24-year-old ends the season with a 3.12 ERA, 1.07 WHIP and 98:32 K:BB in 89.1 innings with the Reds and looks primed to receive the Opening Day nod next year.
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.
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.
Castillo may only make one or two starts in September before being shut down for the season, Zach Buchanan of the Cincinnati Enquirer reports.
Though he's recorded a win in just two of his 13 starts, Castillo has been the Reds' top starter since making the leap from Double-A Pensacola to the majors in late June, submitting a 3.26 ERA, 1.14 WHIP and a 9.7 K/9 rate. However, since he's already accumulated 157.2 innings between both levels and the Reds have previously stated that they would like to keep the rookie around 165 innings for 2017, a shutdown seems imminent. While that will limit Castillo's utility for fantasy owners the rest of the way, manager Bryan Price indicated it won't have any bearing on the right-hander's status heading into 2018. Price has already stated that the 24-year-old is a lock to open next season as a member of the rotation.
Castillo (2-7) allowed one run on three hits and one walk while striking out nine across seven innings to take the loss Saturday against the Pirates.
Castillo pitched five shutout innings, but his only mistake was giving up a home run to opposing pitcher Gerrit Cole, which led to his seventh loss of the season. He's been very solid over his last three outings, as he's allowed just three earned runs over 17 innings of work, and despite his poor winning percentage, fantasy owners have benefited by his 3.26 ERA to go along with a 1.14 WHIP. He'll make his next start Friday against the Pirates.
Castillo (2-6) allowed two runs on four hits and two walks while striking out eight batters through just four innings during Sunday's loss to Atlanta.
Castillo has now allowed three earned runs or fewer in each of his past five starts and owns a 3.45 ERA, 1.19 WHIP and 9.5 K/9 for the season. Those numbers move the needle in all fantasy settings, and the 24-year-old righty's value is on the rise. It will be difficult to rack up wins starting for the basement-dwelling Reds, but otherwise, there's a lot to like about Castillo's upside moving forward. He lines up to face the Pirates at Busch Stadium in his next start.
