The Diamondbacks selected Castillo's contract from Triple-A Reno on Thursday.
ANALYSIS
Castillo got a late start to the season with Reno due to an adductor injury, but he made five appearances there and allowed just one run with a 7:0 K:BB over 5.1 innings. The left-hander missed much of 2024 with a hand injury, and when he makes an appearance, it will be his first in the majors since 2023.

Past Fantasy Outlooks
2021
2020
2019
2018
Castillo's 2020 season was over before it could begin. The lefty went down during an intrasquad game in July and was diagnosed with a Grade 2 lat strain, with the injury ultimately forcing a move to the 45-day IL and costing him the entire year. That was after he missed nearly all of 2019 with a forearm flexor strain and a tendon tear in his left hand. The Padres reinstated Castillo to the 40-man roster in November of 2020 and made a point to say that he was healthy heading into the winter. He showed a lot of promise in 2018, riding his fastball-slider combo to a 34.7 K% and 14.0 SwStr% in his first spin around the majors. Castillo is now a wild card given we have barely seen him over the past two seasons. If he's finally healthy, he should be a big difference-maker in the late innings for San Diego.

Latest Fantasy Rumors
Could be ready for 2021
Castillo might be ready to pitch during the 2021 MLB season, according to Kevin Acee of the San Diego Union-Tribune.
ANALYSIS
Castillo missed the entire 2020 MLB season and, even though general manager A.J. Pollock said he could've been ready to pitch in the postseason if needed, Castillo didn't feel at his best and his return to the mound has been postponed until next year. The left-handed reliever has a 3.23 ERA in 39 innings pitched during his MLB career but has appeared in just one game since the beginning of the 2019 season.
