Chaparro is expected to begin the season as the Nationals' primary designated hitter, Jessica Camerato and Paige Leckie of MLB.com report.

Luis Garcia is shifting to first base and Daylen Lile should be the primary right fielder, leaving DH available for Chaparro. The 26-year-old hasn't done much yet in the majors to suggest he's capable of providing consistent offense, however, slashing .203/.268/.358 in 205 plate appearances for the Nats over the last two years with just five homers. He's also struggled this spring, batting .154 (6-for-39) with two home runs and a 6:12 BB:K. If Chaparro can't step up, he could be the player who loses his spot when it's time for Dylan Crews or Robert Hassell -- both of whom will begin the year with Triple-A Rochester -- to get another look.

House slashed .429/.444/.786 over 16 Grapefruit League games this spring with six doubles and three home runs.

The 22-year-old third baseman also had a 1:11 BB:K, however, creating plenty of doubt as to whether House will be able to maintain that momentum into the regular season. He's locked into the starting job at the hot corner, but he'll need to significantly improve his plate discipline to get to his power after he managed just a 2.9 percent walk rate against a 28.5 percent strikeout rate as a rookie in 2025.

Pirates manager Don Kelly said Sunday that he plans to use Triolo as the team's everyday shortstop to begin the season, Colin Beazley of the Pittsburgh Post-Gazette reports. "Just feel like he's been so good at short in his limited time last year," Kelly said of Triolo. "He's good anywhere you put him. But just felt like being a shortstop, having him there when he's on the field is really important."

A Gold Glove Award winner as a utility man in 2024, Triolo continued to provide strong defense at multiple infield spots in 2025, logging 44 starts at shortstop, 30 at third base, 12 at first base and 10 at second base. He'll carry eligibility at the former two positions in most fantasy leagues heading into 2026, but the Pirates seemingly want to deploy Triolo on more of a full-time basis at shortstop rather than shifting him all over the infield as needs arise. Triolo has already proved that he belongs in the big leagues defensively, but the jury is still out as to whether he's worthy of a regular spot in the everyday lineup. The 28-year-old owns a mediocre 87 wRC+ over parts of three seasons in the big leagues, but he took a major step forward in the second half of 2025, slashing .276/.353/.422 (117 wRC+) with four home runs and eight stolen bases across 216 plate appearances.

Muncy went 1-for-3 with a walk, a run and an RBI in a spring win over the Angels on Sunday.

Muncy's RBI came on a bases-loaded walk in the third inning. The veteran third baseman has performed well during the exhibition slate, posting a .333/.429/.583 slash line with three home runs, seven RBI, eight runs and a 6:8 BB:K through 14 games. Muncy has missed over 150 games due to injury over the past two seasons, so staying healthy would go a long way toward firming up his fantasy value.

Suarez was slotted fifth in the batting order in the two games since he returned from the World Baseball Classic, Mark Sheldon of MLB.com reports.

Since Suarez was signed by Cincinnati at the beginning of February, the general consensus was that he'd bat fourth, and that's where he was in four of his first five Cactus League games before departing for the WBC. Reds manager Terry Francona explained the batting-order experiment, indicating the reconfigured lineup (with Sal Stewart batting cleanup) might generate more RBI opportunities for Suarez. However it shakes out, Suarez will be a middle-of-the-order bat for the Reds in 2026.

Vargas is expected to be on Arizona's Opening Day roster, after the team reassigned Jacob Amaya to minor-league camp Sunday, Steve Gilbert of MLB.com reports.

The Amaya transaction seemingly resolves the roster fates of Vargas, Jorge Barrosa and Tim Tawa. Vargas received the news well Sunday, going 1-for-4 with a two-run home run in a Cactus League contest against the Padres. He's batting .378 (17-for-45) with four doubles, two homers and nine RBI over 15 spring games. He's expected to serve as a backup utility infielder along with Tawa, who will also find time in the outfield.

Karros will begin the 2026 season on the big-league roster, Thomas Harding of MLB.com reports.

Karros was the favorite to claim the third-base job coming into spring training, and his performance during the exhibition season aligned with those expectations. He collected 15 hits -- four of which went for extra bases -- and struck out only nine times in 41 plate appearances. Karros will presumably draw the majority of starts at third base to begin the season, though his role hasn't been defined.

Miranda was reassigned to minor-league camp by the Padres on Sunday.

Miranda inked a minor-league contract with San Diego in December, and he was able to join the team as a non-roster invitee during spring training. The 27-year-old compiled a strong .304 average with two home runs, nine RBI and six runs scored over 46 at-bats in 22 contests during Cactus League action. Miranda is now likely headed to Triple-A El Paso for the beginning of the 2026 campaign.

Manager Warren Schaeffer said Sunday that Rumfield has secured a spot on the Rockies' Opening Day roster, Thomas Harding of MLB.com reports.

Rumfield had been attending camp as a non-roster invitee but will wind up breaking camp with the big club after slashing .286/.368/.531 with four home runs and one stolen base across his 57 plate appearances in Cactus League play. The Rockies will officially add Rumfield to the active roster shortly before Friday's season opener in Miami. Though Schaeffer didn't specifically outline what Rumfield's role will look like, the 25-year-old should be in line for regular starts at first base to begin the season, at least against right-handed pitching. The right-handed-hitting Kyle Karros could be a candidate to spell the left-handed-hitting Rumfield when the Rockies face southpaws.

The Rockies reassigned Machin to minor-league camp Thursday.

Machin will likely begin the season at Triple-A Albuquerque after he was unable to win a utility spot on the Rockies' Opening Day roster. The 32-year-old resurfaced in the majors for the first time since 2022 as a member of the Orioles organization last season, appearing in four games and going 1-for-11 with a solo home run.
