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.

To open bullpen game
PTampa Bay Rays
October 7, 2019
Castillo will be the first pitcher in a bullpen game for Game 4 of the ALDS against the Astros on Tuesday, Juan Toribio of MLB.com reports.
ANALYSIS
Bullpen games helped get the Rays to the playoffs, so there's little reason for them to stop now. The team has yet to announce who will follow Castillo.
