Casas (knee) will be "out a while" with what is now being described as a likely oblique issue, Chris Cotillo of MassLive.com reports.

Casas opened the season on the 10-day injured list while continuing to rehab from left knee surgery. He had been swinging a bat but was shut down in early April with what was initially deemed a left intercostal strain. Casas tried to resume swinging less than a week later, but that didn't go well, and he was consequently sent in for an MRI. While Boston is still waiting for the results of that imaging, manager Alex Cora said Saturday that the organization is now treating the issue "like an oblique, rib injury." Cora added, "He's going to be out for a while but we're still waiting for the news from the doctor."

Lowe went 1-for-4 with a three-run double during the Reds' 7-3 win over the Angels on Saturday.

Lowe gave the Reds a 4-0 lead in the first inning after a bases-clearing, three-run double off George Klassen (finger). Lowe has been limited to a bench role early on in the season, and he doesn't have a clear path to regular playing time unless Sal Stewart were to miss time.

Murakami went 0-for-3 with a walk and two strikeouts during the White Sox's 2-0 loss to the Royals on Saturday.

Murakami opened his first MLB season strongly with three home runs in three consecutive games and was up to four homers and seven RBI through eight contests. However, he has cooled off at the plate of late, going 1-for-20 with six walks, three runs scored and nine strikeouts in his past seven games. These types of growing pains are to be expected for Murakami, but he'll have plenty of runway to work on his game after signing a two-year, $34 million contract with the White Sox in December.

Walker isn't in the lineup for Saturday's game versus the Mariners, Chandler Rome of The Athletic reports.

Walker went 0-for-3 with a walk and a run scored in Friday's series opener, breaking what had been a six-game hitting streak. He'll get a day off Saturday while Isaac Paredes gets the nod at first base and bats third.

Polanco (Achilles) will start at designated hitter and bat third against the Athletics on Saturday.

Polanco has been in and out of the Mets' lineup recently with Achilles problems and sat out the Mets' last two games following his Achilles bursitis diagnosis, but he's seemingly feeling well enough to return to the starting nine Saturday. The 32-year-old has slashed .200/.289/275 across his first 45 plate appearances with New York.

Smith went 3-for-4 with two runs scored and two RBI in Friday's win over the Guardians.

The 30-year-old has had an impressive start to the season as a strong-side platoon option at designated hitter. Through 10 games, Smith is slashing .357/.400/.571 with two homers, eight runs and eight RBI, but his playing time could take a hit once Sean Murphy (hip) comes off the IL.

Manzardo went 1-for-4 with a solo home run in Friday's 11-5 loss to Atlanta.

Manzardo popped his first home run of the season in the fourth inning. The Guardians expected to see Manzardo take a next step in 2026, but he's off to a slow start. He entered Friday batting .086 (3-for-35) with one RBI and a 34.1 strikeout percentage.

Olson went 1-for-4 with a two-run homer, one walk and an additional run scored during Atlanta's 11-5 win over Cleveland on Friday.

Olson powered Atlanta's six-run rally in the sixth inning, taking Slade Cecconi deep to right field for a two-run homer to put his team up 4-2. Olson has smacked a two-run home run in back-to-back games and is up to four long balls on the season. He has reached base safely in each of his last 11 games, and over that span, Olson has gone 12-for-42 (.286) with four homers, 10 RBI, eight walks and 10 runs scored.

Guerrero went 3-for-5 with two doubles, two runs scored, one steal and an RBI during Toronto's 10-4 win over Minnesota on Friday.

Guerrero notched his first steal of the season in the seventh inning before being brought home on an RBI single by Davis Schneider, and the former drove in a run of his own on a double in the eighth. Guerrero has just one home run through 13 regular-season games, but he currently boasts a .429 OBP.

Diaz went 2-for-4 with a two-run homer during Friday's 5-3 win over the Yankees.

Diaz tied the game at 2-2 in the bottom of the first inning after smacking a two-run homer to right-center field off Luis Gil. It was Diaz's third home run of the season and second since the calendar flipped to April, and he has five multi-hit games early on in 2026. He has gone 19-for-51 (.373) with nine runs scored, 12 RBI and one steal through 13 regular-season games.
