Signs with Arizona
PArizona Diamondbacks  AAA
February 11, 2025
Curtiss signed a minor-league contract with the Diamondbacks on Tuesday that includes an invitation to spring training.
ANALYSIS
Most of Curtiss' time last season was spent at Triple-A Albuquerque, where he turned in a 3.96 ERA and 1.32 WHIP over 50 regular-season frames. However, his recent performance in the majors hasn't been as successful, as he's surrendered 14 earned runs in 22 regular-season innings since 2023. He'll have an opportunity to earn a spot at the end of Arizona's bullpen during spring training, but chances are he reports to Triple-A Reno to begin the 2025 campaign.

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.
Curtis had an impressive season at Triple-A last year with a 1.85 ERA and 12.3 K/9. He struggled in his first trip to the majors with a 8.31 ERA and allowing nine hits and two home runs in 8.2 innings. However, he had a 10.4 K/9 in the majors. He should be back in the majors at some point this summer due to his velocity (95.2 mph average fastball) and decent control. He could have a high-leverage role in the bullpen eventually if he can improve his off-speed pitches.
The 6th-round 2014 draft pick had an impressive 12.5 K/9 between High-A and Low-A last season. He then followed up with a 2.84 ERA and 12.8 K/9 in the Arizona Fall League. He'll begin in Double-A and could advance rapidly as the Twins are in need of bullpen arms with high strikeout rates.

Set for bullpen spot?
PNew York Mets  AAA
March 26, 2023
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.
