John Curtiss - MLB News, Rumors, & Updates

Loses out in bid for roster The Diamondbacks reassigned Curtiss to minor-league camp Sunday, Alex Weiner of ArizonaSports.com reports.

Impact Curtiss appears set to begin the season in the bullpen at Triple-A Reno after he was touched up for three earned runs on five hits and two walks over 5.2 innings in Cactus League play. The 32-year-old righty could earn another look in the majors at some point in 2026 if he can rediscover the form he displayed last season across his two stints with Arizona. He collected four holds and accrued a 3.93 ERA, 0.93 WHIP and 24:5 K:BB in 36.2 innings out of the Diamondbacks bullpen in 2025.

Re-ups with Diamondbacks The Diamondbacks re-signed Curtiss to a minor-league contract Tuesday.

Impact Curtiss had chosen free agency after being booted off Arizona's 40-man roster last month, but he's now back in the organization on a new deal. The 32-year-old pitched well in 30 relief outings for the Diamondbacks in 2025, collecting a 3.93 ERA, 0.93 WHIP and 24:5 K:BB over 36.2. Curtiss is likely headed to Triple-A Reno to begin the 2026 season.

Outrighted to Reno Curtiss cleared waivers Wednesday and was sent outright to Triple-A Reno, Alex Weiner of ArizonaSports.com reports.

Impact Curtiss finished the 2025 campaign with a 3.93 ERA and 0.93 WHIP alongside a 24:5 K:BB across 36.2 innings. However, with the Diamondbacks aiming to clear roster space before free agency begins, the 32-year-old righty will lose his place on the 40-man. He will have the option to elect free agency.

Earns first save of season Curtiss allowed a hit in a scoreless inning to earn the save in Saturday's 4-3 win over the Phillies.

Impact Curtiss is the 17th player to log a save for the Diamondbacks this season, which has seen the team take a closing committee to the extreme. Andrew Saalfrank has been bothered by shoulder fatigue recently and may not have been available, as he was not deployed despite his last appearance being Tuesday. Curtiss was hit hard in an outing Wednesday versus the Giants, allowing five runs (four earned) without recording an out, but he bounced back well. He's pitched to a 3.86 ERA, 0.94 WHIP and 21:5 K:BB through 35 innings while adding a save and four holds.

Selected from Triple-A The Diamondbacks selected Curtiss's contract from Triple-A Reno on Saturday.

Impact 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.

Signs with Arizona Curtiss signed a minor-league contract with the Diamondbacks on Tuesday that includes an invitation to spring training.

Impact 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 frames. However, his recent performance in the majors hasn't been as successful, as he's surrendered 14 earned runs in 22 innings since 2023. He'll have a chance 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.

Goes unclaimed The Rockies outrighted Curtiss to Triple-A Albuquerque on Aug. 9.

Impact Curtiss would have had the option of electing free agency after he cleared waivers, but he instead chose to stick around in the Colorado organization as relief depth at the Triple-A level. He's made two appearances for Albuquerque since clearing waivers, covering one inning while giving up one earned run on three hits.

Impact Curtiss joined the Rockies' bullpen in late July and coughed up four runs over 2.1 innings in his three appearances. Chasen Shreve will absorb his roster spot.

Impact Curtiss will take Ty Blach's spot on the 40-man and 26-man rosters and will serve as a depth piece for a Colorado bullpen that just traded Nick Mears to the Brewers. Curtiss has made one appearance with the Rockies this season, yielding two runs in one-third of an inning. He logged a 4.03 ERA in 38 innings for Albuquerque.
