2023 Fantasy Outlook
Castillo worked as both a starter and a reliever between the Blue Jays and the Royals last season, as he was included in part of the return for Whit Merrifield. He was better as a Blue Jay, as Castillo ended the year in rough form. Overall, his 5.95 ERA, 1.35 WHIP and 37:15 K:BB across 39.1 innings aren't great numbers, but there's room for him to grow. The 23-year-old right-hander will be in contention for a spot in the Kansas City rotation heading into 2023 -- there are a lot of pitchers in that mix, but youth is on his side if he can get back on track. Castillo leans heavily on a 93 mph fastball and also features a changeup and a slider in his three-pitch mix. Realistically, there's a significant chance he opens the season at Triple-A, though his performance in spring training will likely be a key one to watch as the Royals shape their pitching staff under a new manager and pitching coach.

Moves to Triple-A
The Royals optioned Castillo to Triple-A Omaha on Tuesday.
ANALYSIS
Castillo was needed for 4.2 innings out of the bullpen in Sunday's loss to the White Sox, so he probably wasn't going to be available for at least another day or two. Nick Wittgren was called up from Triple-A to replace Castillo on the 26-man active roster.
