Moll could make the Reds' Opening Day roster as the Reds' second left-hander out of the bullpen, C. Trent Rosecrans of The Athletic reports.

Caleb Ferguson's oblique injury has created the extra roster space for another left-hander, with Moll following Brock Burke in the pecking order.

The Diamondbacks reassigned Hatch to minor-league camp Thursday, Alex D'Agostino of SI.com reports.

Hatch joined Arizona on a minor-league deal in January after he spent the 2025 season in the Royals and Twins organizations, logging a 5.82 ERA, 1.68 WHIP and 22:17 K:BB over 34 big-league innings between the two stops. After the right-hander was unable to win a spot on Arizona's Opening Day roster, he'll likely serve as a swingman at Triple-A Reno to begin the 2026 campaign.

The Diamondbacks reassigned Jarvis to minor-league camp Thursday, Alex D'Agostino of SI.com reports.

Jarvis made 12 appearances at the big-league level for Arizona in 2025, submitting a 5.73 ERA, 1.50 WHIP and 21:10 K:BB in 22 innings. He was outrighted off the 40-man roster in December and now appears set to open the season at Triple-A Reno after he was unable to break camp with a spot in the Diamondbacks bullpen.

The Diamondbacks reassigned Dubin to minor-league camp Thursday, Alex D'Agostino of SI.com reports.

Dubin had been attending camp as a non-roster invitee and was unable to secure a spot in Arizona's Opening Day bullpen after giving up four runs (two earned) on four hits and three walks over five innings in Cactus League play. The 30-year-old righty spent the 2025 season in the Astros and Orioles organizations, making 30 appearances in the majors while pitching to a 5.08 ERA, 1.43 WHIP and 28:11 K:BB across 33.2 frames.

The Diamondbacks reassigned Campbell to minor-league camp Thursday, Alex D'Agostino of SI.com reports.

Plenty of spots in Arizona's Opening Day bullpen were up for grabs in spring training, but Campbell was unable to seize one despite allowing just two baserunners over five innings across six Cactus League appearances. Campbell saw big-league action in each of the past three seasons but is slated to begin the 2026 campaign at Triple-A Reno.

The Cardinals optioned Fernandez to Triple-A Memphis on Sunday.

The right-hander made 32 relief appearances for St. Louis last year but struggled to a 7.71 ERA and 1.71 WHIP in 30.1 innings. Fernandez wasn't any better during spring training with eight runs allowed and a 7:5 K:BB across six frames, so he'll begin 2026 at Triple-A.

Fulmer (elbow) struck out a batter over two perfect innings of relief Friday in the Pirates' 7-5 win over the Tigers in Grapefruit League play.

Fulmer was making his first appearance of the spring, after he had been delayed due to his late signing in addition to completing his recovery from a right elbow strain that caused him to close last season on the shelf. Since the right-hander is attending camp as a non-roster invitee, he'll be facing an uphill battle to win a spot in the Opening Day bullpen, but he put a strong foot forward Friday.

The Phillies reassigned Mercado (shoulder) to minor-league camp Thursday, Todd Zolecki of MLB.com reports.

Mercado made three appearances out of the Philadelphia bullpen in 2025, but a right shoulder injury prevented him from making any Grapefruit League appearances and will end his bid for an Opening Day roster spot. The Phillies haven't shed much light regarding where Mercado stands in his throwing program, making it unclear if he'll be ready for the start of the minor-league season.

The Mets reassigned Edwards to minor-league camp Sunday.

Edwards, who made four appearances in the big leagues last season between the Angels and Rangers, had been attending camp as a non-roster invitee. He was impressive with 11 strikeouts in 8.2 innings while holding hitters to a .103 batting average, but the Mets didn't have a spot available for him in their Opening Day bullpen.

The Diamondbacks reassigned Curtiss to minor-league camp Sunday, Alex Weiner of ArizonaSports.com reports.

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 if he can rediscover the form he displayed last season across two stints with Arizona last year, when he collected four holds and accrued a 3.93 ERA, 0.93 WHIP and 24:5 K:BB in 36.2 innings.
