Betts will undergo an MRI on his back Saturday evening, Jack Harris of the California Post reports.

Betts was removed from Saturday's game against the Nationals in the first inning with lower-back pain, and the Dodgers will send him for testing to determine the extent of the issue. Manager Dave Roberts described the injury as "more moderate than significant," though he is already ruling Betts out for at least the next couple days. Miguel Rojas and Alex Freeland are candidates for playing time at shortstop while Betts is sidelined.

Robert isn't in the lineup for Saturday's game against the Giants.

Robert will stay put in the dugout to begin Saturday's contest after going 1-for-6 with three walks, an RBI and a run scored during the first two games of the series. Jared Young, Carson Benge and Brett Baty will form the Mets' outfield trio while Robert rests.

Alvarez isn't in the lineup for Saturday's game against the Giants.

Alvarez will get a breather after slugging a pair of solo homers during Friday's win. Luis Torrens will replace him behind the plate and bat ninth.

Polanco (Achilles) will serve as the designated hitter and bat third against the Giants on Saturday.

Polanco's Achilles tendinitis has limited him to working mostly as a DH to begin the regular season, and manager Carlos Mendoza said that the 32-year-old infielder began experiencing renewed discomfort Thursday. Polanco now appears to be feeling well enough to return to his role as New York's DH, though he may not be ready to start every day quite yet.

Soto was diagnosed with a minor strain in his right calf Saturday, Mike Puma of the New York Post reports.

The Mets will hold Soto out of the lineup for Saturday's game against the Giants, but no decision has been made yet on whether to place him on the injured list. The 27-year-old outfielder is optimistic that he'll be able to avoid a trip to the IL, but the team could end up putting him on the shelf if he isn't feeling better within a few days.

The Brewers returned Zastryzny (shoulder) from his rehab assignment Saturday after he suffered a setback in his recovery, Todd Rosiak of the Milwaukee Journal Sentinel reports.

It's unclear whether Zastryzny's setback is related to his strained left shoulder or some other issue, but it will extend his stay on the injured list all the same. He's slated to undergo further testing in Milwaukee within the next few days, at which point more details regarding his new return timeline will emerge.

Vargas went 2-for-2 with two walks, two doubles, two runs scored and a stolen base in Saturday's 6-3 win over the Blue Jays.

The third baseman was a constant thorn in the side of Toronto pitching as he continued an impressive start to the season. Through eight games, Vargas is batting .280 (7-for-25) with three doubles, a homer, six RBI, eight runs and a surprising three steals -- already halfway to the career-high six he swiped in 2025.

Manager Kevin Cash said Saturday that Walls (oblique) has progressed to playing in games at extended spring training, Marc Topkin of the Tampa Bay Times reports.

The next step for Walls is presumably to head out on a rehab assignment in the minors, but the Rays don't have a timetable in place for when that might happen. Once he's cleared to return to the active roster, the 29-year-old could compete with Carson Williams for starts at shortstop, as the latter has slashed just .130/.167/.174 during his first seven games of the season.

Dominguez gave up a hit and a walk in a scoreless ninth inning Saturday to record his first save of the season in a 6-3 win over the Blue Jays. He struck out one.

The 31-year-old right-hander needed 24 pitches (14 strikes) to get the job done, but Dominguez came away with his first save since signing a two-year, $20 million contract this winter to be the White Sox closer. Over four appearances to begin the season, he sports a 1-1 record with a 4.91 ERA, 1.64 WHIP and 3:2 K:BB over 3.2 innings.

Kay didn't factor into the decision in Saturday's 6-3 win over the Blue Jays, giving up two runs on three hits and two walks over 4.1 innings of relief. He didn't strike out a batter.

Facing the team he made his big-league debut with back in 2019, the southpaw took the mound as a bulk reliever after Grant Taylor has worked a scoreless first inning. Kay kept the goose eggs coming until Vladimir Guerrero touched him up for a two-run shot in the sixth, and he exited after 76 pitches (46 strikes). Kay is still looking for his first MLB win since 2021 after spending the last two seasons in Japan, and he'll take a 4.00 ERA, 1.33 WHIP and 5:6 K:BB through nine innings into his next outing, which is set to come on the road next week in Kansas City.
