Winker (side) is expected to be placed on the injured list, Anthony DiComo of MLB.com reports.

Winker suffered a right side injury in the Mets' Game 1 loss to St. Louis on Sunday, and he will require additional testing back in New York. The outfielder may be dealing with an oblique issue, which typically leads to a stint on the injured list. In his absence, Starling Marte stands to see more usage at designated hitter with the Mets.

Manager Carlos Mendoza said Sunday after the Mets' 6-5 loss to the Cardinals in the first game of a doubleheader that Winker (side) will undergo an MRI, Andrew Tredinnick of The Bergen Record reports.

Winker walked and delivered an RBI sacrifice fly in his two plate appearances in Game 1 before being pulled from the contest prior to the bottom of the fourth inning due to right side discomfort. Mendoza noted that Winker -- who suffered the injury while throwing to home plate in the bottom of the third inning -- will be sent in for tests as the Mets look to determine whether he suffered an oblique strain. Winker won't be available for the second game of the twin bill Sunday, and his availability for the Mets' three-game series in Arizona that begins Monday also seems to be in doubt.

Bell (groin) is out of the lineup for Sunday's game against the Reds, Mark Zuckerman of MASNSports.com reports.

Bell will sit for a second straight game due to a groin issue. The veteran slugger didn't see any action Saturday but was reportedly available to pinch hit, so he'll presumably be available in that capacity Sunday.

Winker was lifted from the first game of Sunday's doubleheader with the Cardinals ahead of the bottom of the fourth inning due to right side discomfort, Anthony DiComo of MLB.com reports.

Winker drew a walk in the first inning and hit an RBI sacrifice fly in the third, but it's unclear if he picked up the injury on any of his swings or while he was playing defense in left field. Regardless, Winker will be on the bench for the rest of the matinee, and his availability for the nightcap would seem to be in doubt. Jeff McNeil shifted from second base to left field in the bottom of the fourth upon Winker's removal from the game.

Smith is out of the lineup for Sunday's game against the Phillies.

Platoon mate Randal Grichuk will replace Smith as the Diamondbacks' designated hitter while the Phillies send southpaw Ranger Suarez to the bump. Smith has logged just eight plate appearances against lefties all season.

McCutchen is out of the lineup for Sunday's game against the Padres.

McCutchen will receive a breather after serving as Pittsburgh's designated hitter for 12 straight games, slashing .298/.377/.511 during that stretch. The Pirates will give Joey Bart a day off from catching and deploy him as the DH in place of McCutchen.

Sheets is out of the lineup for Sunday's game against the Pirates.

The left-handed-hitting Sheets will remain on the bench for the second day in a row while the Pirates send another lefty (Andrew Heaney) to the bump. Luis Campusano will replace Sheets as the Padres' designated hitter.

Steer went 2-for-5 with a double, two RBI and a run scored in Saturday's 11-6 loss to Washington.

He struggled at the beginning of the season while able to serve only as a designated hitter due to a shoulder issue, but since Steer has been cleared for defensive duties, his bat has come alive. Prior to April 20, Steer had a .390 OPS with three RBI over 15 games. Since then, he has an .851 OPS with eight RBI over 12 games.

Ohtani went 3-for-4 with a solo home run, two additional runs and a walk in a 10-3 win against Atlanta on Saturday.

Ohtani broke a 1-1 tie with a 415-foot solo homer to center field in the third inning. He reached base three other times in the rout and pushed his league-leading runs-scored total to 35. Ohtani's role as Los Angeles' leadoff hitter has been a factor in his accumulation of just 11 RBI so far this season, but the two-way star has otherwise been excellent with a .293/.396/.569 slash line while maintaining a 40-40 pace with eight homers and nine stolen bases through 31 games.

Bell isn't starting Saturday against the Reds due to a groin issue, but he could be available to pinch hit, Spencer Nusbaum of The Washington Post reports.

It doesn't sound like the Nationals are very concerned about Bell's injury, as Nusbaum notes that the team is "being careful" due to wet weather conditions. The veteran slugger's potential availability to pinch hit also suggests he isn't dealing with a serious issue. With Bell out of his customary DH role Saturday, James Wood is getting a day out of the field as the designated hitter while Alex Call is getting a start in left field.
