Solano optioned in favor of rookie replacement Dietrich

MIAMI -- Marlins second baseman Donovan Solano was reinstated from the 15-day disabled list on Monday after missing a month with an intercostal strain.

However, he is not returning to Miami.

The Marlins optioned Solano to Triple-A New Orleans, choosing instead to stick with his replacement, rookie Derek Dietrich.

"Unfortunately, in this game, sometimes when you get hurt, it's not a guarantee that you're going to be back out there when you're healthy," manager Mike Redmond said. "Dietrich came up, he got an opportunity, and he's done a tremendous job. He's gotten some huge hits for us."

Dietrich's latest huge hit was an eighth-inning home run against the Mets on Sunday at Citi Field. The leadoff solo shot tied the game at four and forced extra innings, paving the way for Miami's 8-4 win.

The clutch blast from Dietrich was also historic.

He became only the 13th player whose first five career home runs have either tied a game or given his team the lead. He joins a list that includes Eric Chavez, Tony Batista and Ken Griffey Jr.

Dietrich, who batted third in the order in 23 of his first 27 games, moved down to sixth on Monday to accommodate the return of Giancarlo Stanton and Logan Morrison.

"He's come out, and he's done a great job, and he's won that job," Redmond said.

Solano, who batted .295 in 93 games last season, was on a hot streak before he became injured. He had raised his batting average from .239 to .278 with a 15-for-43 stretch and owned a six-game hitting streak.

"I know it's tough," Redmond said. "Guys get injured, and they go down. But at the same time, too, there's not a guarantee that your job's going to be there when you get back.

"A lot of guys get hurt, and they just never make it back. It happens."

Polanco listed as day to day with back stiffness

MIAMI -- Placido Polanco left the Marlins' game against the Brewers on Monday with lower back stiffness. He is listed as day to day.

Ed Lucas entered the game during the bottom of the sixth to pinch-hit for Polanco, who may have suffered the injury while leaning over Miami's dugout railing in pursuit of a popup off the bat of Carlos Gomez in the top of the fifth.

Polanco nearly tumbled over the railing, but Lucas and catchers Miguel Olivo and Rob Brantly ran over to keep the 17-year veteran from falling.

"He didn't tell me," Miami manager Mike Redmond said of the extent of Polanco's injury. "He just said his back had tightened up on him, so we had to get him out of there. I don't know if it was on the railing or what."

The third baseman has been dealing with back issues since last season, playing only 90 games with the Phillies. He was also briefly sidelined in early March during Spring Training.

Polanco is batting .227 with seven RBIs and 19 runs in 207 at-bats. He has committed only one error in 52 games for a fielding percentage of .991.

With Stanton hitting third, Dietrich moves to sixth

MIAMI - Giancarlo Stanton returned to the Marlins lineup Monday night, settling right back into his customary third spot in the batting order.

However, the names on manager Mike Redmond's lineup card have changed dramatically since he's been gone.

Perhaps the most significant difference since Stanton went to the DL with a right hamstring strain on April 29 is the establishment of rookie outfielder Marcell Ozuna in the No. 4 spot.

Ozuna, who filled in for Stanton in right field, has blossomed as Miami's cleanup hitter, batting .331 with 17 RBIs, 18 runs scored and 67 total bases in 142 at-bats.

"We'll see how that goes throughout the course of the season, but right now with Stanton we want to get him up there and as many at-bats we can in the game and get him back in the flow," Redmond said. "Ozuna has done a great job in the four-hole, and he's gotten some big hits for us and driven in some big runs."

First baseman Logan Morrison, who played his first MLB game since July in the Marlins' 8-4 win against the Mets on Sunday, hit fifth Monday night.

Morrison finished 2-for-4 with a walk and a run scored in his first game back.

"LoMo had good at-bats hitting fifth," Redmond said.

Returning Stanton and Morrison help Miami's lineup with more than simply additional bats. Derek Dietrich, who has hit third since May 14, moved down to sixth on Monday night.

"I think it for sure, without a doubt strengthens our lineup. It stretches out our lineup where we can drop Dietrich down a little bit father in the order," Redmond said. "The middle of our lineup is more of a threat. I think that's good. We've obviously been waiting for this day for a while. But I'm happy with the way we've grinded it out."

Marlins get 'fresh start' with return of LoMo, Stanton

MIAMI -- When told that the past few months of the season couldn't be erased, Marlins first baseman Logan Morrison responded: "Why can't you?"

A day after Morrison made his 2013 debut, slugger Giancarlo Stanton returned from the 15-day disabled list.

"I give the guys a lot of credit," manager Mike Redmond said. "They kept battling, kept playing hard. I have to be honest with you -- getting LoMo back yesterday -- you could just sense and feel that guys were excited, and knowing Stanton was coming back today has definitely energized this team."

Juan Pierre admitted that the lineup offers a different dynamic with Stanton, rookie Marcell Ozuna and Morrison hitting back-to-back-to-back in the middle of the order.

"Definitely for the whole scheme of things and where we're trying to go as an organization, it definitely helps to have those guys around to plug into the [Derek] Dietrichs and Ozunas -- guys not supposed to be but are here because of injuries and [have] proven that they belong," Pierre said.

Despite holding the worst record in the Majors at 18-44, Miami remains optimistic with 100 games remaining in the regular season. Over the past 10 games, the Marlins are 5-5. They have won two of their last three series.

"I wasn't here, so it's a fresh start for me," Morrison said. "I've just got to bring that attitude to these guys, and hopefully it wears off. Every day's a new day, and it's the beginning of a new season.

"Don't worry about the records, the standings, just continue to compete and have the attitude that they're competing with us, we're not competing with them. I think that will go a long way."

Worth noting

• According to Redmond, Chris Coghlan had an MRI and results were expected late Monday or early Tuesday. Coghlan was placed on the 15-day DL Sunday with right calf nerve irritation.

• Right-hander Nathan Eovaldi's rehabilitation start on Sunday was rained out after one inning. He will make another on Thursday at Double-A Jacksonville and be re-evaluated. Right-hander Henderson Alvarez will begin his rehab assignment on Thursday in Jupiter. Neither pitcher has made his 2013 debut because of right shoulder inflammation.

• Infielder Donovan Solano and first baseman Joe Mahoney were reinstated from the DL and optioned to Triple-A New Orleans on Monday.
