St. Louis activated Carpenter (oblique) from the 10-day injured list prior to Saturday's game against the Brewers.

Jose Fermin had been leading off against lefties, but with the Cardinals set to face three right-handed starters in a row, Fermin was sent to Triple-A Memphis, and the lefty-hitting Carpenter was added to the active roster. The 38-year-old designated hitter went 3-for-10 with a run scored in three games before getting injured April 1.

Senzel is out of Saturday's lineup against the Red Sox.

He will sit for a second day in a row with the Nationals facing a right-handed starting pitcher, and on both occasions Victor Robles has picked up the start in the outfield with Jesse Winker sliding to designated hitter. Senzel is hitting .214 with a 42.4 percent strikeout rate in 28 at-bats this month.

Schwarber (back) will sit for Saturday's game against the Marlins, as expected.

He left Friday's game in the ninth inning with a sore back and told reporters he'd probably take Saturday off, which is indeed the case. Cristian Pache draws the start in left field with Whit Merrifield starting at third base and Alec Bohm getting the nod at designated hitter. Schwarber's back was still a bit tight Saturday, per manager Rob Thompson, and they're taking it day by day, Alex Coffey of The Philadelphia Inquirer reports.

Schwarber left in the ninth inning of Friday's 8-2 win over the Marlins due to a sore back, per MLB.com.

Schwarber's back tightened on his last swing in the seventh inning, and Kody Clemens came in to pinch hit in the ninth frame. Schwarber noted that he'll "probably take [Saturday] off... hopefully I'll wake up [Saturday] feeling better, and we'll keep going." The 31-year-old went 2-for-5 with a two-run single in Friday's win.

Bryant (back) took batting practice prior to Friday's game against the Rangers, MLB.com reports.

Bryant began the session cautiously, just getting the ball out of the infield. However, he was able to pull the ball over the fence by his final swings, a positive sign for his recovery. There hasn't been a date set yet, but Bryant is expected to begin a rehab assignment soon.

Senzel is not in the lineup for Friday's game in Boston.

Senzel closed out April with a power surge, but the strikeouts have piled up on him in May, as he's whiffed at a 42.4 percent rate in seven contests. He'll get a day off to regroup. Jesse Winker will be the Nationals' designated hitter Friday, while Eddie Rosario will hold down left field.

Carpenter (oblique) is on track to rejoin the Cardinals on Saturday in Milwaukee, Rob Rains of StLSportsPage.com reports.

Carpenter will play in one more rehab game with Triple-A Memphis on Friday before a likely return to the big club. Out since early April with a right oblique strain, Carpenter has gone 4-for-17 with two homers in his first five rehab contests. Upon his activation, Carpenter could see some starts at designated hitter versus righties for an offense that's desperately looking for a spark.

Bryant (back) did infield drills and hit in the batting cage prior to the Rockies' game against the Giants on Wednesday, Patrick Saunders of the Denver Post reports.

Bryant has progressed slowly since landing on the injured list, and it has since been disclosed that he has disc and arthritis issues in his lower back. He took a step forward Wednesday, making his first participation in baseball activities since being sidelined. Manager Bud Black noted that Bryant will likely need a rehab assignment, meaning there's a good chance he won't be activated until at least late May.

Pederson went 3-for-5 with a solo home run, a stolen base and an additional run scored in Thursday's 5-4 win over Cincinnati.

Pederson opened the scoring with a solo shot off Hunter Greene in the first inning, his fourth long ball of the year. Pederson had gone just 2-for-15 in four games coming into Thursday's contest. He's still slashing a solid .302/.415/.535 with 15 runs scored and eight RBI through 33 games this season as Arizona's primary DH against right-handed pitching.

Ozuna went 2-for-3 with two home runs and four RBI in Wednesday's win over the Red Sox.

Ozuna jumped on a hanging four-seamer from Nick Pivetta in the bottom of the first and launched it into the stands in right field for a three-run shot to put Atlanta on the board. The veteran slugger followed up with another long ball in the third, this time a solo shot on the first pitch he saw, giving him a league-leading 12 home runs on the season. Ozuna also leads the major leagues in RBI with 38 and has now driven in at least one run in three straight games.
