Steer started in left field and went 2-for-3 with a double, a stolen base, two RBI and two runs scored in Thursday's 8-2 win over the Nationals on Opening Day.

Steer was part of a productive lower-half of the order, which combined to go 8-for-19 and was responsible for all eight runs and RBI. He has eligibility at multiple positions, but the offseason plan was to use him primarily in the outfield. Steer led the team in home runs (23) and RBI (86) last season while stealing a fantasy-helpful 15 bases.

The Rangers placed Lowe (oblique) on the 10-day injured list Thursday.

Lowe will be eligible to come off the IL ahead of the Rangers' April 5 game against the Astros, but the team is expecting him to be ready to return from his right oblique strain around mid-to-late April, per MLB.com. Jared Walsh and Ezequiel Duran are expected to form a platoon at first base to begin the season until Lowe is ready to return.

Freeman went 2-for-3 with a two-run homer and an additional RBI in Thursday's 7-1 win over St. Louis.

Freeman got the scoring started Thursday with an RBI single in the first inning before cranking a two-run homer off Miles Mikolas in the third. The 34-year-old Freeman is coming off a stellar 2023 campaign where he slashed .331/.410/.567 with 29 home runs, 102 RBI and a career-high 23 steals. He has a chance to be even more productive this year, batting in the third spot behind Mookie Betts and Shohei Ohtani in a star-studded Dodgers lineup.

Goldschmidt went 3-for-4 with a solo home run in Thursday's 7-1 loss to the Dodgers.

Goldschmidt accounted for all three of the Cardinals' hits Thursday, including a fourth-inning homer off Tyler Glasnow that stood at St. Louis' lone run in the Opening Day defeat. The veteran first baseman slashed .268/.363/.447 last season with 25 home runs and 80 RBI. The Cardinals are counting on Goldschmidt to provide a similar offensive presence in the middle of their order this year.

Walsh is out of the lineup Thursday against the Cubs.

The Cubs will send southpaw Justin Steele to the mound to start their season, so the lefty-hitting Walsh will begin Opening Day in the dugout. Ezequiel Duran will instead start at first base and bat seventh.

The Rangers selected Walsh's contract from Triple-A Round Rock on Thursday.

Walsh was able to win a spot on Texas' Opening Day roster after putting up an .827 OPS with three home runs this spring. He's likely in line to see most of the at-bats at first base against right-handed pitching while Nathaniel Lowe (oblique) is on the shelf.

The Cubs selected Cooper's contract from Triple-A Iowa on Thursday.

Cooper posted a .927 OPS with three long balls this spring to secure a spot on the Cubs' Opening Day roster. He figures to mostly play against lefties but offers an option at designated hitter and will also provide protection at first base for Michael Busch.

Horwitz was optioned to Triple-A Buffalo on Sunday.

The 26-year-old came into camp hoping to land a backup job at first base behind Vladimir Guerrero, but Horwitz batted only .125 (5-for-40) in Grapefruit League action, and the signings of Daniel Vogelbach and Joey Votto (ankle) cut off his path to the 26-man roster. Horwitz slashed .337/.450/.495 with 10 homers in 107 games for Buffalo last season, but he may need to add more power to his profile to get serious consideration for a regular job in the majors.

O'Hearn is absent from the lineup for Thursday's season opener versus the Angels.

The Angels are rolling out southpaw Patrick Sandoval, so Ryan Mountcastle will be at first base and Jordan Westburg will serve as the designated hitter. O'Hearn will be a regular against righties, either at first base or DH.

Sano will start at designated hitter and bat seventh in Thursday's season opener versus the Orioles.

Not only did Sano make the team after going to camp as a non-roster invitee, but he will be part of the batting order for Opening Day. The Angels could still ultimately rotate through multiple players in the DH spot, but Sano's power gives him some deep-league relevancy should he find regular playing time.
