Through nine spring appearances, Estrada has tossed 9.2 scoreless innings, giving up two hits while posting a 16:7 K:BB.

Estrada has looked nearly unhittable in exhibition action while racking up a 14.9 K/9. The walks are a bit concerning, though the flamethrowing reliever is coming off a 2025 regular season during which he posted a career-best 8.9 percent walk rate. Estrada also recorded a career-high 30 holds last year and is slated to again be a key high-leverage arm for San Diego in 2026.

Leahy will open the season in the Cardinals' rotation, Daniel Guerrero of the St. Louis Post-Dispatch reports.

Leahy's regular-season debut will occur March 30 with a start at home against the Mets. The right-hander has not been used as a starting pitcher regularly since 2022, but he often worked multiple innings out of the Cardinals' bullpen last season and was stretched out as a starter this spring, finishing with a 4.58 ERA and 20:5 K:BB over 17.2 frames. Leahy has not reached 90 innings in any of the last three seasons while being used in the bullpen, so he's sure to face some form of workload restrictions in 2026.

Lopez said Monday that he is fine physically and mechanical issues are to blame for his diminished velocity during Sunday's Grapefruit League outing versus the Twins, Mark Bowman of MLB.com reports.

Lopez averaged just 89.2 mph with his four-seamer in the start, yielding four runs on five hits and two walks over 4.2 frames. The right-hander's velocity has been down all spring, though not to the level it was Sunday. Lopez could see an uptick in velocity after the regular-season adrenaline kicks in, but it's also possible this is the new normal for him as he comes back from shoulder surgery. The 32-year-old is scheduled to make his season debut Saturday against the Royals and should probably be left on fantasy benches for the time being.

The Diamondbacks informed Ross on Sunday that he'll be included on the Opening Day roster, Nick Piecoro of The Arizona Republic reports.

Ross, who had been attending camp as a non-roster invitee, submitted a 7.71 ERA, 1.57 WHIP and 6:5 K:BB in seven innings during Cactus League play. The 32-year-old has worked primarily as a starter during his career but will operate as a multi-inning reliever for Arizona.

The Pirates reassigned Clevinger to Triple-A Indianapolis on Monday.

He was in camp as a non-roster invitee and logged a 5.02 ERA, 1.40 WHIP and 15:10 K:BB in 14.1 innings this spring. Jose Urquidy beat out Clevinger for the final long-relief spot in the Pirates' Opening Day bullpen.

The Padres reassigned Gillaspie to minor-league camp Sunday.

Gillaspie is likely to open the upcoming season as a swingman at Triple-A El Paso, where he finished the 2025 campaign after being outrighted off the Padres' 40-man roster in July. Prior to losing his roster spot, Gillaspie appeared in three big-league games for San Diego last season, covering seven innings while allowing two earned runs on seven hits and four walks.

Ferguson (oblique) is scheduled for a second MRI on March 25 to determine he's healing well, MLB.com reports.

If doctors feel like Ferguson is making progress, the left-hander could begin a throwing program. He was expected to be unavailable for start of the regular season but is pegged to return at some point in April.

The Padres optioned Adcock to Triple-A El Paso on Tuesday.

Adcock failed to win an Opening Day roster spot in a deep Padres bullpen, despite letting in just one earned run on four hits and no walks over his four innings in Cactus League play. The 29-year-old righty has seen limited big-league action over the past three seasons between stops with the Mariners and Mets, logging a 5.48 ERA, 1.04 WHIP and 19:4 K:BB in 23 innings.

Nicolas was optioned to Triple-A Louisville on Sunday.

Nicolas will head to Louisville after having appeared in one contest with the Reds during spring training, giving up one run on four walks over two-thirds of an inning. The right-hander was dealt to the Reds in exchange for outfielder Tyler Callihan on March 4, but he ultimately saw limited action during the spring with Cincinnati. Nicolas will now have to wait for his next chance with the major-league roster.

The Cubs reassigned Martin to minor-league camp Sunday.

Martin made 17 appearances in the big leagues with Baltimore in 2025, but he lost his spot on the 40-man roster in September and then signed a minor-league deal with the Cubs over the winter. The veteran righty was unable to secure a spot in the Cubs' Opening Day bullpen and is expected to begin the season at Triple-A Iowa.
