Marlins looking to secure momentum in games

MIAMI -- At a time the Marlins are starting to score some runs, they're being victimized by allowing them right back.

Perhaps it is a sign of fatigue in the final month of the season. Or perhaps it is a lack of focus. Clearly, it is a lapse in executing pitches. But the Marlins saw it in losing two of three to the Nationals over the weekend after they took the series opener.

In Sunday's 6-4 loss, Miami saw a two-run lead disappear immediately after it was obtained. The Marlins went ahead 3-1, but a half inning later, the Nationals tied the score.

"We've had a tough time over the last couple of weeks with shutdown innings," manager Mike Redmond said. "We've scored some runs, and it seems like we're in a rut where we're giving up a run or a big hit or a couple of runs right back, and we lose that momentum."

Miami's pitching has been its strength all season. But in its first seven games of September, the team's ERA is 4.21, which ranks 15th in the Majors.

The Marlins even received a couple of breaks on Sunday when Stephen Strasburg committed two balks, which plated runs, in the same inning.

"We came out and scored some runs against a tough pitcher," Redmond said. "We just weren't able to lock it down and secure that lead. We gave the momentum right back. Against a good pitcher, you've got to take advantage of things. We know we've got to pitch and play almost perfect to win."

Stanton takes part in warmups, could return Tuesday

MIAMI -- Maybe a couple of days of rest is all Giancarlo Stanton needs to get back in the lineup.

The Marlins slugger tested his sore right ankle on Monday afternoon by taking batting practice. Earlier in the day, Stanton took some swings in the batting cage, and he said he felt fine.

With his ankle taped, the 23-year-old right fielder participated in a number of pregame warmups before Miami's series opener against the Braves at Marlins Park.

"Best case, tomorrow he's ready to go," Miami manager Mike Redmond said. "But it really is up to him. We're going day to day. When he says he is good to go and ready to play, he will play."

Stanton rolled his ankle on the first-base bag while attempting to beat out a grounder in Atlanta on Sept. 1.

He had been playing through some discomfort, but on Saturday night, he experienced more severe pain and was replaced in the eighth inning in Miami's 9-2 loss to the Nationals.

On Sunday, Stanton was given the whole day off, and he received treatment.

Chris Coghlan has replaced Stanton in right field, and Justin Ruggiano is playing center while batting cleanup.

Depending on how he feels Tuesday, there is a chance Stanton could return to the lineup for the second of four games with the Braves.

"We'll see how he feels," Redmond said.

Marlins mulling giving Turner extended rest

MIAMI -- The Marlins are not planning on shutting Jacob Turner down, but they are trying to come up with ways to enable the 22-year-old to end the season on a high note.

Turner was roughed up for five runs on nine hits in four-plus innings in Sunday's 6-4 loss to the Nationals.

It's been a rough second half for the right-hander, who is 0-5 with a 4.53 ERA in 10 starts since the All-Star break.

On Tuesday, manager Mike Redmond said he is talking with pitching coach Chuck Hernandez about how to get better results in the final three weeks. That may mean giving him more time between starts.

Turner is lined up to start on Friday against the Mets. However, the team is looking at where they could push his start back to.

"We're going to look at some different things and see what we're going to do, and decide," Redmond said. "Maybe get him a couple of extra days, we'll see."

Turner opened the season at Triple-A New Orleans before joining the Marlins' rotation on May 31.

For the season, Turner is 3-6 with a 3.43 ERA in 18 starts. Turner has run up 107 2/3 innings with Miami, and 164 total counting 10 outings with New Orleans.

"I don't think we will shut him down," Redmond said. "That's what we're trying to figure out now. How many more starts, how many more innings?"

After his loss on Sunday, Turner said part of his struggles were because of poor execution of his fastball.

"It's just something where I'm not making the pitches when I need to make them," Turner said. "The biggest thing is not commanding my fastball the way I need to. It's very frustrating, but it's something I've got to work through. Hopefully, in my next start it will be better."

The Marlins have a doubleheader against the Mets on Saturday, and Henderson Alvarez is scheduled to pitch the first game, with Brad Hand lined up for Game 2.

Ace Jose Fernandez will be shut down after his start on Wednesday, and it appears Brian Flynn will fill that spot, meaning he would be set to go on Sept. 16 at Philadelphia.

The Marlins track out their rotation about two weeks ahead.

"That's what we've done, and mapped out a few different options of how we're going to use guys," Redmond said. "We've got some flexibility with guys."
