Martinez started in left field and went 1-for-4 with a double in Saturday's 6-5 extra-inning win over Seattle.

Martinez parlayed a productive spring (1.196 OPS) into an Opening Day roster spot but not a role as a lineup regular. The Guardians have a few outfield prospects on the roster, including the red-hot Chase DeLauter (four HR), so Martinez may be limited to one or two starts per week. When George Valera (calf) is ready to rejoin the team, that could further cap opportunities for Martinez, or even lead to a demotion to the minors.

Seager went 2-for-4 with a solo home run and a walk in Saturday's 5-4 win over the Phillies.

Seager took a 92-mph fastball from Aaron Nola over the fence for his first home run of the season in the top of the first inning. Seager later singled in the fifth inning. Through two games, Seager is 4-for-8 at the plate with the home run and a pair of runs scored. The veteran shortstop was limited to 102 games last year due to hamstring issues and an appendectomy, but he was productive when available with 21 homers and an .860 OPS.

Arias isn't in the lineup for Saturday's game versus Seattle.

Arias has gone 1-for-7 with three strikeouts through the first two games of the season and will step out of the lineup for the third game of Cleveland's four-game set against the M's. Brayan Rocchio will slide over to shortstop while Daniel Schneemann mans the keystone.

Baez is not in the Tigers' starting lineup against the Padres on Saturday.

The Tigers will tweak their lineup for Saturday's game, moving Kevin McGonigle to shortstop and Colt Keith to third base while Kerry Carpenter serves as the designated hitter. Through two regular-season games, Baez has gone 1-for-7 with one walk and two strikeouts.

Neto went 2-for-5 with a solo home run, an additional run and a double against Houston in a 6-2 win Friday.

Neto capped the scoring in the victory with a solo shot in the ninth inning. The talented young shortstop went 0-for-5 in the Angels' season opener Thursday, but he turned things around with the two extra-base hits one game later. Neto is among fantasy's most coveted shortstops after recording a .793 OPS with 26 homers and 26 stolen bases over 128 contests last year.

Pena is not in the Astros' starting lineup against the Angels on Saturday, Matt Kawahara of the Houston Chronicle reports.

Pena will take a seat after going 2-for-5 with a run scored and a stolen base in Friday's 6-2 loss to the Angels. Carlos Correa will shift over to shortstop while Isaac Paredes gets the start at third base Saturday. Pena appears fully recovered from the fractured fingertip he sustained in early March, but the Astros may continue to monitor his workload in the early going after he missed most of spring training.

Alexander is not in the Orioles' starting lineup against the Twins on Saturday.

Alexander drew the start at second base Thursday, going 1-for-3 with an RBI single in the seventh inning. He'll be on the bench for the start of Saturday's game while Jeremiah Jackson starts at the keystone and bats ninth.

Muncy is starting at third base and batting seventh in Saturday's game against the Blue Jays.

Muncy started at the hot corner for Opening Day on Friday against Toronto, going 0-for-3 with two strikeouts. It looks like the 23-year-old is the A's preferred option at third base to open the 2026 regular season, though Andy Ibanez and Darell Hernaiz could see some starts of their own if Muncy struggles early on. Muncy made his major-league debut in March of 2025 and finished last season with a .638 OPS with one steal, nine home runs and 23 RBI over 220 plate appearances.

Clement went 2-for-4 with two doubles and a run scored in Friday's win over the A's.

It was a strong start to the season for the 30-year-old infielder, who's expected to be Toronto's everyday second baseman now that Andres Gimenez is sliding over to shortstop to replace Bo Bichette. Clement posted a respectable .277/.313/.398 slash line in 2025 with nine homers and six steals in 157 regular-season games while bouncing all around the infield, but having a stable defensive home could allow him to find another level at the plate.

Barger is not in the Blue Jays' starting lineup against the Athletics on Saturday.

With left-hander Jeffrey Springs taking the mound for the Athletics on Saturday, Barger will open the contest in the dugout while the Blue Jays go with Davis Schneider, Daulton Varsho and Myles Straw in the outfield from left to right. Barger went 0-for-4 with a strikeout on Opening Day on Friday.
