Martini (thumb) began a rehab assignment with Triple-A Louisville on Saturday.

Martini had originally been targeting Tuesday as the start date for his assignment, so it's possible the 34-year-old is ahead of schedule in his recovery. It's unclear how many games he will play in the minors, though there's still a good chance he rejoins the Reds before the end of the season.

Martinez is out of the lineup for Friday's game against the Phillies.

After starting at DH in three consecutive games, Martinez will give way to Jesse Winker on Friday. Martinez is 3-for-21 (.143) with four RBI in September.

Schwarber (elbow) will DH and bat leadoff Friday against the Mets.

Schwarber was scratched from Wednesday's lineup due to elbow pain stemming from an awkward dive back to first base on a pickoff Tuesday. All indications are that the injury is minor, and he's feeling well enough to play Friday. The 31-year-old has 35 home runs and a .868 OPS on the year.

The Mets outrighted Reyes to Triple-A Syracuse on Friday, Anthony DiComo of MLB.com reports.

The Mets DFA'd Reyes on Monday, and the shortstop has elected to remain in the Mets organization after clearing waivers. The 30-year-old was traded from Boston to New York in May, but he's yet to log an at-bat for the Metropolitans.

Rosario is out of the lineup for Thursday's game against the Cardinals.

After a recent stretch of 10 starts in an 11-game span, Rosario now finds himself on the bench for the second straight day, with both absences coming against right-handed pitchers. Though Rosario looked to be gaining traction as the Reds' primary designated hitter, the team has seemingly pulled the plug on using him as an everyday player while he's managed a lowly .184/.216/.245 slash line since being claimed off waivers from the Dodgers on Aug. 18. The Reds may instead prefer to rotate a number of players at the DH spot rather than giving consistent at-bats to the struggling Rosario.

Ohtani went 2-for-4 with a home run, three RBI, a walk and a stolen base in Wednesday's win over the Cubs.

Ohtani wasted no time in getting the Dodgers on the board, launching a 405-foot leadoff homer off Jordan Wicks in the opening frame. The superstar slugger would then draw a leadoff walk in the second before going on to swipe his 48th bag of the campaign, and he later added a two-run single in the third to extend the Dodgers' lead. Ohtani has now recorded multiple hits in four of his last six games, batting .333 (8-for-24) over that stretch with three homers, five RBI and five runs scored. He's also gone deep five times over his last 12 contests.

The Phillies scratched Schwarber from the lineup for Wednesday's game against the Rays while he continues to experience soreness in his left elbow, Todd Zolecki of MLB.com reports.

Schwarber was removed in the fourth inning of Tuesday's 9-4 win, after he looked to have injured his elbow while diving back into first base on a pickoff attempt the inning prior. Though the Phillies initially penciled Schwarber into the lineup Wednesday, manager Rob Thomson said that the designated hitter is still experiencing soreness in his elbow when he swings. The Phillies have Thursday off, so the club is seemingly hopeful that Schwarber will be ready to serve as the DH in Friday's series opener versus the Mets after two full days of rest.

Rosario is not in the lineup for Wednesday's contest in St. Louis.

Rosario had started in the designated-hitter spot in eight of the last nine games, but he will get a day off Wednesday. Noelvi Marte will serve as the Reds' DH in Rosario's stead.

Schwarber (elbow) will bat leadoff as the Phillies' designated hitter in Wednesday's game against the Rays.

Schwarber was pulled from Tuesday's 9-4 win in the fourth inning, after he had previously appeared to have hurt his elbow an inning earlier when he retreated to first base on a pickoff attempt. His inclusion in the lineup a day later likely suggests that his removal was precautionary, so fantasy managers in leagues with daily lineup moves shouldn't have many qualms about keeping the slugger active Wednesday. Schwarber has opened September with a nine-game hitting streak, during which he's slashed a scintillating .417/.463/1.083 with seven home runs, 13 RBI and 12 runs.

Pederson is out of the lineup for Wednesday's game against the Rangers.

Lefty Cody Bradford is on the hill for the Rangers, so the lefty-hitting Pederson will head to the bench in the series finale. Pederson's absence will clear the way for Josh Bell to pick up a start as Arizona's designated hitter.
