2020 Fantasy Outlook
Castillo proved to be a jack-of-all-trades for the Rays in 2019, working as both a setup man and closer -- finishing with 17 holds and eight saves -- while also starting six games as an opener. He was dialed in for the first two months of the season before struggling in June and subsequently landing on the injured list with a shoulder issue. Castillo returned after the All-Star break and showed no ill effects, posting a 2.88 ERA and 1.17 WHIP over 34.1 second-half innings with a 43:10 K:BB and 0.8 HR/9 over that stretch. His skill set, which includes a fastball that touches triple digits with a swing-and-miss slider, is reminiscent of a closer; while Emilio Pagan was traded, the Rays used a committee at times and could do so again in 2020 as they still have a plethora of viable endgame options. Either way, Castillo should see high-leverage work and is a good bet to see at least some save chances. Read Past Outlooks

Records win in '20 debut
PTampa Bay Rays
July 28, 2020
Castillo (1-0) was credited with the win in Monday's rout of the Braves, firing a scoreless fifth inning during which he didn't allow any hits or walks and recorded two strikeouts.
ANALYSIS
Just activated from the paternity list earlier in the day, Castillo was put right to work after starter Tyler Glasnow already had Toronto hitters reeling with nine strikeouts over the first four frames. Castillo kept up the trend of missing bats, firing eight of his 10 pitches into the strike zone while retiring Austin Riley and William Contreras for his two strikeouts. The right-hander's strong start is an encouraging sign manager Kevin Cash has yet another viable weapon in his bullpen arsenal to attack with in the shortened season.

Stat Review
How does Diego Castillo compare to other relievers?
This section compares his stats with all relief pitcher seasons from the previous three seasons (minimum 30 innings)*. The bar represents the player's percentile rank. For example, if the bar is halfway across, then the player falls into the 50th percentile for that stat and it would be considered average.

* Exit Velocity, Barrels/BBE %, Balls Hit 95+ MPH %, and Spin Rate are benchmarked against 2019 data (min 30 IP). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.

2019 Fantasy Outlook
Castillo posted strong numbers in his debut campaign, recording a 3.18 ERA backed up by a strong 29.3% strikeout rate. He technically logged 11 starts, though all came firmly in the "opener" role, as none lasted more than two innings. With a 98-mph fastball, an 89-mph slider and a strong minor-league track record, Castillo's performance looks legitimate and repeatable. He has the skill set to eventually get a look in the closer role. The team may prefer his flexibility and willingness to work in the opener role for the time being. The job exposes him to the toughest part of the opposing order more often and hurts his chances for wins, but also gives him to a larger workload than is typical for a reliever -- he worked 1.3 innings per outing last season -- which helps him rack up more strikeouts.
