Stewart went 2-for-2 with a walk, a double and a run scored in Sunday's 3-2 win over the Red Sox.

There was no let-up for Stewart in the third game of the season. He's now had multiple hits and reached base at least three times in all three games, going 7-for-10 with three walks, zero strikeouts and more extra-base hits than singles. He also showed advanced baserunning Sunday, advancing to second base on a flyout to center field, which put him in a position to reach third base when the next batter singled to left field.

Steer started at first base and went 1-for-4 in Sunday's 3-2 win over Boston.

Steer made his first start of the season at first base after serving as the left fielder Thursday and Saturday. The plan announced this spring, when Steer started at five different positions, was that he would primarily play left field but could also slot in at various spots. In addition to his starting positions thus far, Steer also moved mid-game Saturday to first base and then third base. That roster flexibility helps manager Terry Francona navigate in-game situations, while also ensuring Steer gets a full game of plate appearances.

Horwitz will start at first base and bat sixth in Sunday's game against the Mets.

Heading into spring training, the 28-year-old's role was somewhat muddled following the offseason additions of Marcell Ozuna, Ryan O'Hearn and Brandon Lowe, but Horwitz looks to have settled into a strong-side platoon role at first base. He's occupied the position for the Pirates' first two games against right-handed pitchers, with O'Hearn spelling him Saturday when the Mets sent lefty David Peterson to the hill.

Smith went 1-for-4 with a grand slam in Saturday's 6-2 win over the Royals.

Smith played the role of hero Saturday, crushing a walk-off grand slam in his team debut to punctuate Atlanta's six-run comeback in the ninth inning. With Sean Murphy (hip) on the injured list to begin the year and Jurickson Profar suspended for the entire season, the left-handed-hitting Smith has a clear pathway to at-bats at designated hitter versus right-handed pitching for the time being.

Stewart went 2-for-4 with a solo home run, two RBI and a walk in Saturday's 6-5 win over the Red Sox.

Stewart's wrist soreness, which stems from being hit by a 110-mph liner Opening Day, didn't seem to be an issue Saturday, as he stayed hot at the plate. The first baseman had an RBI single in the first inning and then took Sonny Gray deep in the third. Batting cleanup for Cincinnati, Stewart is 5-for-8 with two doubles, one home run and two RBI through two games to begin the regular season.

The Brewers placed Vaughn on the 10-day injured list Saturday with a hamate fracture in his left hand.

Vaughn made an early exit from Thursday's game against the White Sox after hitting a single in the sixth inning, and imaging revealed a fracture afterwards. He's slated to undergo surgery Monday and will miss roughly 4-to-6 weeks. Jake Bauers and Gary Sanchez will be in the mix for starts at first base while Vaughn is out, and Jeferson Quero will come up from Triple-A Nashville to offer depth at catcher while freeing up Sanchez to occasionally start at first.

Stewart will start at first base and bat fourth Saturday against the Red Sox.

Concerns regarding Stewart's health arose after he took a 110-mph Roman Anthony line drive off his wrist in the fifth inning of Thursday's contest, but Stewart said Saturday that he only feels a little sore and will continue to play, per Gordon Wittenmyer of The Cincinnati Enquirer. The 22-year-old infielder finished the season opener 3-for-4 with a pair of doubles and is poised to start most games at first base for the Reds, though he's also capable of covering second or third.

Santana started at first base and went 1-for-3 with a walk, a double and a run scored in Friday's 5-4 loss to the Dodgers.

Santana started the first two games of the regular season at first base against right-handers, while the lefty-swinging Pavin Smith dealt with an elbow issue early in the regular season. Those two are expected to share first base and DH early on. Designated hitter will become more crowded when Lourdes Gurriel (knee) is ready to rejoin Arizona. The soon-to-be 40-year-old Santana is coming off a 2025 season in which he posted a career-low .325 slugging percentage (11 HR, 22 XBH).

France will start at first base and bat seventh in Friday's game versus the Tigers.

After the lefty-swinging Gavin Sheets started at first base Opening Day against southpaw Tarik Skubal, the Padres will go with the right-handed-hitting France versus lefty Framber Valdez. San Diego is expected to give Sheets plenty of run at first base against lefties this season, but France and Nick Castellanos will also be in the mix at the position.

O'Hearn went 2-for-4 with a solo home run and two runs scored Thursday against the Mets.

O'Hearn took Tobias Myers yard in the sixth inning to tally his first home run of 2026 as well as with the Pirates. O'Hearn led off the final frame with a single and came around to score his second run of the contest. He started in right field and hit fifth in the order, and he should continue to hold a prominent role in Pittsburgh's lineup against right-handed pitchers.
