The Rockies optioned Herrera to Triple-A Albuquerque on Sunday, Patrick Lyons of JustBaseball.com reports.

The 21-year-old lefty was added to Colorado's 40-man roster in November but was never a likely bet to make the Opening Day roster. Herrera spent most of last season with Double-A Hartford, where he had a 3.69 ERA, 1.30 WHIP and 70:19 K:BB across 46.1 innings.

The Diamondbacks optioned Holman to Triple-A Reno on Sunday, Alex Weiner of ArizonaSports.com reports.

Holman tossed a scoreless inning in his lone Cactus League appearance to date, but having a pair of minor-league options remaining might have hurt his cause for breaking camp as a member of the Diamondbacks' Opening Day bullpen. With the Athletics last season, the 25-year-old righty made 22 appearances (two starts) at the big-league level, logging a 5.09 ERA, 1.52 WHIP and 17:9 K:BB in 23 innings.

The Diamondbacks optioned Burgos to Triple-A Reno on Sunday, Alex Weiner of ArizonaSports.com reports.

Burgos was one of 15 players dismissed from big-league camp in the Diamondbacks' latest round of roster cuts. The 26-year-old righty was unable to secure a spot in Arizona's Opening Day bullpen after yielding four earned runs on six hits and two walks over 2.1 innings in the Cactus League.

Garcia (illness) struck out three batters over two perfect innings in his last two Cactus League appearances Wednesday and Saturday.

During his second appearance of the spring Feb. 28, Garcia was lifted early after falling ill, but he needed just a few days to move past the issue. The 25-year-old lefty has allowed just two total baserunners over three innings this spring, putting him in good shape to break camp as a member of the Diamondbacks' Opening Day bullpen.

Ort (elbow) struck out one batter in a perfect inning of relief Thursday in the Angels' 16-11 loss to the Athletics in Cactus League play.

While he was a member of the Astros last season, Ort didn't make any appearances after Sept. 4 due to right elbow inflammation. The right-hander was briefly a member of the Yankees' 40-man roster over the offseason before being claimed off waivers in late January, and New York outrighted him just over a week later. Ort is attending big-league spring training as a non-roster invitee and will look to string together a few more quality relief appearances in the Cactus League to make his case for a spot in the Angels' Opening Day bullpen.

The Mariners optioned Loutos to Triple-A Tacoma on Sunday.

Scooped up off waivers from the Nationals earlier in the offseason, Loutos will begin his time in the Mariners organization at the Triple-A level after he was unable to secure a spot in the Opening Day bullpen. The right-hander took himself out of consideration after yielding seven runs (six earned) on seven hits over three innings in four appearances during Cactus League play.

The White Sox announced Sunday that Smith will start their March 26 season opener in Milwaukee.

Coming off a rookie season in which he earned an All-Star nod while pitching to a 3.81 ERA and 1.20 WHIP over 29 starts, Smith was the obvious choice to take the hill for the Opening Day game. The 25-year-old righty will be facing off against the organization that drafted him in 2021 before he joined the White Sox in the Rule 5 Draft following the 2024 season.

Leahy struck out five across four perfect innings in Saturday's Grapefruit League start against the Mets.

Leahy bounced back from a rough second spring training outing with a stellar effort Saturday, requiring only 47 pitches to cruise through his four frames. The right-hander remains a favorite to capture one of the final spots in the Cardinals' rotation, and that the club is considering opening the year with a six-man setup would only increase his chances.

The Pirates optioned Harbin (lat) to Triple-A Indianapolis on Sunday.

Harbin isn't expected to resume throwing until at least early April after he sustained a right teres major muscle tear early in camp, so his demotion to Triple-A was fully anticipated. Indianapolis is likely to place Harbin on its 7-day injured list shortly before the International League season gets underway.

Latz allowed three runs on two hits and three walks while striking out three over 3.1 innings in Saturday's spring start against the Giants.

Latz's third Cactus League start was a grind. After an efficient 1-2-3 first inning, the left-hander needed 18 pitches for the second frame. The walks also drove up his pitch count, and by the time he started the fourth inning, Latz's velocity diminished. Per Evan Grant of the Dallas Morning News, the Rangers have been concerned about Latz's ability to maintain velocity throughout a game and work as a viable starter. He's currently competing with Kumar Rocker for the final spot in the rotation, with Cal Quantrill and Austin Gomber also options if neither favorite is deemed able to handle the assignment.
