The New York Mets received bad news on two players Monday.

Yoenis Cespedes will miss the rest of the season because of a right hamstring strain, while David Wright experienced continued shoulder pain while attempting to come back from last year's neck surgery for a cervical disk herniation.

"After playing in a few games, I continued to have shoulder pain," Wright said in a statement. "So I decided to go to the doctor and get it checked out. Will make any decisions going forward after my appointment."

Wright last played in a Major League game in May 2016.

Cespedes, 31, played in just 81 games this season.

Matt Harvey is scheduled to return to the New York Mets on Friday against the Houston Astros.

He has been on the disabled list for more than two months with a stress injury to his right scapula.

The right-hander was mediocre in four rehab starts. Harvey allowed three earned runs, five overall, in 4 2/3 innings for Double-A Binghamton on Saturday.

"When he threw in Double-A last time, the reports weren't all that glowing," pitching coach Dan Warthen said. "But [minor league pitching coordinator] Glenn Abbott was raving about this last one. Matt's delivery was the same every pitch, and everything was coming out cleanly."

Dodgers manager Dave Roberts said ace Clayton Kershaw came out of his Saturday rehab start at Triple-A well and will next start for Los Angeles either Friday or Saturday.

The three-time Cy Young winner, rehabbing from a lower back strain, threw five innings in his first rehab start for Triple-A Oklahoma City. He allowed one run and two hits, did not walk a batter and struck out eight.

Clayton Kershaw pitched five innings in his first rehab start for Triple-A Oklahoma City on Saturday night and afterward proclaimed himself healthy and ready to return to the Dodgers.

Kershaw, who is rehabbing from a lower back strain, has been sidelined since July 24.

"I feel I've always been ready, but this is part of the process, and I'm glad to get this under my belt and ready to get up there," he said.

Tigers designated hitter Victor Martinez has been placed on the disabled list for the second time this season because of an irregular heartbeat, the team announced Sunday.

The ailment is causing Martinez to suffer from dizziness and shortness of breath.

As Bryce Harper misses baseball while on the disabled list, many of his Nationals teammates are getting close to being healthy again.

Even with Harper still out with a bone bruise in his left knee and no timetable for his return, the Nationals are about to get some reinforcements. Stephen Strasburg is back on the mound, ace Max Scherzer is expected to return Monday and shortstop Trea Turner and outfielder Jayson Werth aren't too far behind.

Add Ryan Zimmerman to the list of walking wounded for the Nationals.

Following Friday's 4-2 loss to the Mets, manager Dusty Baker revealed that Zimmerman, who sat out the game, injured his shoulder sliding headfirst into home plate in the 11th inning of Washington's Thursday night win over the Astros.

Mets outfielder Yoenis Cespedes could be done for the year after straining his right hamstring while running the bases Friday night.

"I'd say [his] season is in jeopardy," general manager Sandy Alderson said after the Mets beat Washington 4-2.

Alderson said the injury is "similar in location and severity to the one on the left side" Cespedes suffered in April. That setback put Cespedes on the disabled list on April 29 and the slugger didn't return until June 10.

Cespedes will be put on the DL and examined Monday in New York.

Michael Conforto has a tear in the posterior capsule of his left shoulder and all treatment options, including surgery, are being considered.

The New York Mets revealed the results of an MRI on Thursday.

Conforto collapsed in pain after swinging at a pitch in the fifth inning against the Arizona Diamondbacks on Thursday.

Initial X-rays on the shoulder revealed a dislocation, but follow-up tests showed the tear. Conforto will go on the disabled list Friday.

"It turns your stomach," manager Terry Collins said. "A player was having a tremendous year and really making a name for himself. To go down like that, and that kind of injury, is tough to watch."

Trevor Rosenthal will have Tommy John surgery on his right elbow, the St. Louis Cardinals have announced.

"I think just the timing of it, being right in the middle of this race and the way my personal season had been taking shape and the way the team has been playing recently. Tough timing," Rosenthal said.

"It felt like we were getting in a groove, I was in a groove, and to kind of have this happen and take a piece away from a really good team is a little bit of a bummer."

Rosenthal, who recorded 93 saves over the 2014 and 2015 seasons, lost the closer's job to Seung-Hwan Oh a year ago but regained it this season after Oh struggled.

Rosenthal will have surgery next week.

"We hoped for better news," Mike Matheny said. "Somebody is going to have to step in. He was really throwing the ball well."
