Vientos (abdomen) isn't in the lineup for Saturday's game versus the Dodgers.

Abdominal soreness prevented Vientos from getting into Friday's contest, and he'll sit out again Saturday while he continues to recover. Brett Baty will start at third base in his absence, and Jared Young will serve as the DH.

The Red Sox are expected to place Bregman (quad) on the 10-day injured list Saturday, Jen McCaffrey of The Athletic reports.

Bregman was removed from Friday's game with right quad tightness while running to first base. That the Red Sox are planning to promote Marcelo Mayer in time for the second game of Saturday's doubleheader against Baltimore indicates Bregman, who was held out of the first game, appears destined for a stint on the injured list. Bregman's loss will be a blow to Boston, as he was hitting .299 with a .938 OPS through 51 games, but it gives the organization a chance to get a look at its top infield prospect.

Rosario (leg) will start at third base and bat second against the Giants on Saturday, Mark Zuckerman of MASNSports.com reports.

Saturday will be Rosario's first start since he received stitches to close a wound he suffered running into a table at the team's hotel last week. The 29-year-old will take the place of Jose Tena at the hot corner against southpaw Kyle Harrison.

Bregman (quad) is scheduled to undergo imaging Saturday, Christopher Smith of MassLive.com reports.

Bregman was removed from Friday's game due to right quad tightness and is not in the lineup for the first game of Saturday's doubleheader. Nick Sogard is starting at third base in the afternoon game.

Baty went 2-for-4 with a walk and a solo home run in Friday's 7-5 extra-innings loss to the Dodgers.

Starting at third base and batting eighth, Baty took Matt Sauer deep in the third inning after play resumed following a lengthy rain delay. Baty has taken over a regular role in the Mets' lineup since returning to the majors earlier this month, and over his last 14 games he's slashing .275/.293/.650 with five of his six homers and 11 of his 15 RBI on the season.

Wagaman went 3-for-5 with a home run and three RBI in Friday's 7-4 loss to the Angels.

Wagaman's solo shot in the seventh inning got the Marlins on the board, and he added a two-run single in the eighth. While the comeback effort fell short, the 27-year-old continues to swing a fairly hot bat. He's hit safely in six of the last seven games, going 11-for-28 (.393) in that span. For the season, he's up to a .253/.302/.398 slash line with four homers, 15 RBI, 20 runs scored, one stolen base, 10 doubles and a triple across 179 plate appearances. Wagaman likely won't sustain his recent success at the plate, but Miami's offense doesn't have enough impact players to create a significant threat to his playing time.

Ramirez went 1-for-4 with a steal, an RBI triple and a run scored in Friday's 3-1 win over Detroit.

Ramirez got the Guardians on the board in the first inning on an RBI triple to right field, and the veteran third baseman came around to score two batters later. Ramirez has reached base safely in 20 consecutive games and is on a 16-game hitting streak, during which he's slashed .381/.451/.683 with five steals, 14 runs scored, four home runs and 10 RBI in 71 plate appearances.

Machado went 2-for-4 with a solo home run in Friday's 2-1 win over Atlanta.

Machado -- who was 2-for-24 in his six games prior to Friday's contest -- put the Padres up for good in the ninth inning when he took Raisel Iglesias deep to left field for a solo home run. It was Machado's first home run since May 3 and fourth of the year. The veteran third baseman has had an inconsistent season, but he's third in the National League in doubles (15) and fourth in batting average (.309).

Vientos was scratched from the lineup ahead of Friday's game against the Dodgers due to abdominal soreness, Andrew Tredinnick of The Bergen Record reports.

The Mets are labelling Vientos' removal from the lineup as precautionary, so while he won't play Friday, he doesn't seem to be dealing with anything serious. Brett Baty will shift over to third base while Vientos sits, and Luisangel Acuna will fill in at the keystone and bat eighth.

The Athletics recalled Alexander from Triple-A Las Vegas on Friday, Martin Gallegos of MLB.com reports.

Alexander will provide some corner-infield depth for the Athletics after Gio Urshela (hamstring) was placed on the 10-day IL on Friday. Alexander appeared in four regular-season games with the Athletics last season, going 1-for-8 at the plate with three strikeouts.
