Rest of Season
Signed a one-year, minor-league contract with the Diamondbacks in February of 2025.
Selected from Triple-A
The Diamondbacks selected Curtiss's contract from Triple-A Reno on Saturday.
Analysis
Curtiss signed a minor-league deal with Arizona in February and has posted a 6.34 ERA, 1.46 WHIP and 28:9 K:BB over 32.2 innings with Reno this season. While those numbers are poor, the righty has been better of late, tossing 3.2 scoreless frames over his past three outings. To make room for Curtiss on the 26-man and 40-man rosters, the Diamondbacks designated fellow reliever Tayler Scott for assignment.

Past Fantasy Outlooks
2021
2018
2017
Following an awful 2019 campaign during which he registered a 7.75 ERA and walked 22 batters in 33 innings between two Triple-A clubs, Curtiss was released by the Phillies and faced an uncertain future. In a career-changing turn of events, the Rays swooped in and did what they do best, helping Curtiss adjust his mechanics and emerge as one of the AL's top middle relievers. The right-hander thrived in his first extended big-league opportunity, posting a 1.80 ERA and 0.96 WHIP over 25 innings. Whereas he couldn't seem to find the strike zone the previous season, Curtiss demonstrated exquisite control in 2020, registering a minuscule 3.0 BB%. Meanwhile, he relied almost exclusively on a mid-90s fastball and effective slider to register a 25.3 K%. Curtiss' 3.57 xFIP portends some regression over a full season, but he's locked into a middle-relief role with an occasional opportunity to open.

Latest Fantasy Rumors
Set for bullpen spot?
Curtiss is in position to secure one of the Mets' final relief roles, per Anthony DiComo of MLB.com.
Analysis
Curtiss is coming off a solid season, logging a 3.45 ERA and an expected ERA of 3.87. The 29-year-old doesn't post stellar strikeout numbers, so he's likely to gain fantasy relevance only if he parlays a strong start into save opportunities at some point.
