MIAMI -- On Tuesday night, Adeiny Hechavarria belted a three-run homer that highlighted the Marlins' 8-2 victory over the Nationals at Marlins Park. Two days later, the 24-year-old shortstop became the latest Miami player to be sidelined by injury.
Hechavarria tweaked his right elbow while fielding a routine grounder during batting practice before Wednesday's game against Washington. He was removed from the lineup and received an MRI in Miami on Thursday before being placed on the 15-day disabled list.
Marlins manager Mike Redmond, who called the injury a bruised elbow, said Hechavarria had no ligament damage.
"It's not a ligament thing, which is great," Redmond said. "It'll just be a matter of taking a break and getting some rest. Hopefully it's a short-term thing."
Redmond believes Hechavarria will be ready to throw in the next week or so.
Injuries keep sidetracking a young club looking to establish continuity. As All-Star outfielder Giancarlo Stanton returns after missing six games with a bruised shoulder, Hechavarria is headed to the DL.
In 14 games, Hechavarria, who turned 24 on Monday, is batting .184, but he has been solid defensively.
The Marlins acquired the Cuban-born shortstop from the Blue Jays last November, and he is one of the core pieces of a rebuilt roster.
Replacing Hechavarria on the active roster is veteran Nick Green, who had his contract selected from Triple-A New Orleans.
Because their 40-man roster was already at its maximum, Miami created space for Green by transferring right-hander Nathan Eovaldi to the 60-day disabled list.
Eovaldi, initially projected to be the No. 2 starter, opened the season on the 15-day DL with right shoulder inflammation. Moving Eovaldi to the 60-day disabled list is a blow to the rotation. He now won't be eligible to be activated until the middle of June, at the earliest.
In their last six games, the Marlins have had to scratch four different players due to injuries.
The Marlins opened a four-game series at Cincinnati on Thursday.
Off to a 3-12 start, the Marlins have already had to use 14 different lineups in 15 games. That will change to 15 in 16 games on Thursday night.
"I'd like to be adding guys -- not adding and subtracting them," Redmond said. "There's not much you can do. We've had a bunch of guys get banged up. We just keep going, keep moving."
Stanton knocks rust off in return to lineup
CINCINNATI -- All-Star outfielder Giancarlo Stanton, who missed six games with a bruised left shoulder, returned to the Marlins' lineup on Thursday, going 1-for-3 with a walk in an 11-1 loss to the Reds.
He also had two errors in right field, both on scoring plays for the Reds -- one in the second inning and one in the fifth.
"He looked comfortable [at the plate]," Marlins manager Mike Redmond said. "He's been out for six days, so it's going to take him some time to get back in the rhythm of seeing pitching and being out there again."
"It's feeling all right -- good enough to be in there," Stanton said before the game. "It's not 100 percent, but it's ready to go."
Stanton tweaked the shoulder while making a diving catch of a ball off the bat of the Mets' Kirk Nieuwenhuis on April 5. Stanton said he felt fine after he made the catch, but he felt some discomfort once the team got back to Miami a few days later.
"[The pain] didn't really come around until we got home," Stanton said. "I didn't even know what to attest it to. [The diving catch] is the only thing I could [think of]."
Stanton missed six games from April 12-17. Miami went 2-4 in his absence.
"Obviously it's nice to have Stanton back in the lineup," Redmond said. "I'm glad he's feeling better. Hopefully the rest did him good -- not just physically, but mentally."
Stanton is batting .167 with no home runs or RBIs in nine games this season. He remains, however, one of the most prolific power hitters in the game; his home run totals have increased from 22 to 34 to 37 in each of his three years in the big leagues.
"I don't like sitting and watching the game," said Stanton, who didn't give an exact percentage on his shoulder. "I'd rather be participating."
Cingrani bests Fernandez in rookies' first meeting
CINCINNATI -- Thursday's 11-1 loss to the Reds featured a matchup of two of the game's best young pitching prospects. Miami's Jose Fernandez, 20, and Cincinnati's Tony Cingrani, 23, are rated No. 7 and No. 66, respectively, among MLB.com's Top 100 Prospects.
Cingrani had the better night, allowing one run and striking out eight in five innings. Fernandez, meanwhile, allowed five runs on six hits in four innings.
Marlins manager Mike Redmond said that youth can be both good and bad.
"I think it can go both ways," he said. "Sometimes the inexperience can affect you with the way you pitch, but at the same time, sometimes the youth is nice because you don't overthink it. You just go out there and throw.
"There's so much video, there's so many stats now, and I think sometimes guys get away from their strengths, especially pitchers. I think when guys struggle, they lose sight of what got them there and what's made them successful."
While Fernandez struggled against the Reds, he allowed just one run in each of his first two big league outings.
"Sometimes with the young players it's fun because they come up and it's like this blank canvas," Redmond said. "You've got this kid with unbelievable talent and you can help mold them and figure out what's going to make them successful. That's the neat thing about young players."
Pierre gets a breather
CINCINNATI -- Miami outfielder Juan Pierre, who has played in every game this season, was not in the starting lineup Thursday night against the Reds. Pierre, 35, had played in all of Miami's 15 games due to a slew of Marlins injuries.
He was replaced in left field by Chris Coghlan.
"I've been wanting to give JP a day off for a while," Marlins manager Mike Redmond said. "We've just needed him to go out there, and he's done a great job grinding it out every single day. We've had to have him play because we've had guys banged up. I told him the other day i wanted to give him a break."
It helps that Reds starter Tony Cingrani is left-handed, so Redmond can avoid the lefty-on-lefty matchup with Pierre on the bench.
Pierre, a career .296 hitter, is hitting .207 with three steals and one RBI in 58 at-bats.
• Major League Baseball has issued a scoring change in the Marlins' 2-1 win over Philadelphia on April 13 at Marlins Park. On the final play of the game, Chris Coghlan was initially credited with a base hit and RBI. That ruling was overturned and changed to a fielder's choice and error on second-baseman Chase Utley.
