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 uber-hot Chase DeLauter (four HR), so Martinez may be limited to one or two starts per week. When prospect George Valera (calf) is ready to rejoin the team, that could further cap opportunities for Martinez or lead to a demotion to the minors.

Tovar went 1-for-4 with a two-run home run Saturday against the Marlins.

Tovar pulled an offering from Eury Perez over the left field fence in the fourth inning for his first home run of the season. He's hit cleanup in each of Colorado's first two games, collecting two hits in eight plate appearances.

McLain went 3-for-4 with an RBI, a run scored and two walks in Saturday's 6-5 win over the Red Sox.

McLain tore the cover off the ball during spring training and is carrying it over to begin the regular season. The second baseman drew an eight-pitch walk in the first inning and later scored on a fielder's choice. He then drove in Ke'Bryan Hayes with an RBI double in his second plate appearance. Through two games, McLain is 3-for-7 at the plate with three walks.

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.

Lawlar isn't in the lineup for Saturday's game against the Dodgers.

Lawlar has started the new season 1-for-7 with three strikeouts across Arizona's first two contests, and he'll now rest his legs during Saturday's series finale. His absence will allow Jorge Barrosa to start in left field and bat ninth.

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.
