Mathis sits with bruised right thumb

MIAMI -- A wild pitch in the fourth inning on Monday night cost the Marlins a run and left Jeff Mathis with a bruised right thumb.

Henderson Alvarez's pitch bounced and caught Mathis' thumb before rolling into foul territory. The Braves scored a run on the play, with Chris Johnson racing home.

Two innings later, Mathis was replaced by Rob Brantly.

Brantly was in the starting lineup on Tuesday for the second of four games against the Braves at Marlins Park.

"I woke up and it was still sore," Mathis said.

An X-ray came back negative, and Mathis is hopeful of returning in a couple of days.

Mathis has been the regular catcher since May, and the 30-year-old has been a steady influence behind the plate for the young Miami staff.

His absence was felt in the first six weeks of the season. Mathis opened the year on the disabled list after sustaining a broken right collarbone in his first Spring Training game.

The fortunes of the team actually started to improve when he rejoined the team on May 16.

"We talked about it in Spring Training when he got hurt," Miami manager Mike Redmond said. "I knew that would be a big blow to us not having that veteran guy around. When we started playing better, it coincided when he got better and he got back. It came when pitching got back, as well."

Mathis has appeared in 66 games, batting .196 with five homers and 29 RBIs. More than his offense, he is being counted on for his defense.

"Having that veteran presence behind the plate is very important in the development of the pitching staff," Redmond said. "He's done a great job."

Coghlan making every game count

MIAMI -- Don't tell Chris Coghlan that the final 20 games of a rough season for the Marlins aren't important.

The 28-year-old, who is overcoming an injury-plagued last few years, is approaching each game with the same desire as if the Marlins were in the playoff picture.

"I don't take it lightly, at all," Coghlan said. "I've got 20 games. That's the way I look at it."

At 53-89, the Marlins are in danger of losing 100 games, if they don't win 10 of their remaining contests.

"You don't want to lose 100 games," Coghlan said. "You do everything you can not to lose 100. It's embarrassing to lose 100. I think we have 10 more wins to make sure we don't lose 100. That's the goal for the team."

Individually, Coghlan has recovered from a nerve-related injury that went from affecting his right calf to his back.

Coghlan was reinstated on Sept. 1, and he is coming off a four-hit night on Monday against the Braves.

Since his return, Coghlan has been used at third base, right field and left field.

"Individually, every game they are evaluating me," Coghlan said. "I don't take any game lightly. I'm not counting the days down, even as badly as it's been for me. It's a tryout. Every day is a tryout. It's a tryout at a new position. It's a tryout at a new place in the lineup."

Coghlan sees these final few weeks as a chance to show his versatility and that he can produce at the plate. He is eligible for arbitration after the season, and isn't sure if he is part of Miami's plans for 2014.

"I don't know what my future holds," he said. "There is good in that, and that you are able to take every game seriously. I think that's what we need to do as a team.

"Sometimes you can get complacent and be like, 'We're young and this and that.' Every game matters up here. Everybody is trying to take bread off your table."

Marlins paying tribute to Bella

MIAMI -- The Marlins are reminding everyone to "Live Like Bella."

During his pregame media session on Tuesday, manager Mike Redmond sported a #LiveLikeBella t-shirt in honor Bella Rodriguez-Torres, the 10-year-old who lost her battle with cancer in May.

At Marlins Park, they are selling #LiveLikeBella shirts to raise funds for the foundation created in her memory.

"They're selling shirts for the children's cancer foundation," Redmond said. "I just wanted to wear the shirt and show support for the foundation. I hope people go out there and pick up some shirts, and they raise some money."

Flynn to start Friday against Mets

MIAMI -- The Marlins have shaken up their rotation for the final three weeks.

Brian Flynn will get the nod against the Mets on Friday night at Citi Field in place of Jacob Turner.

The left-handed Flynn will be making his second start since being a September callup from Triple-A New Orleans.

In his Major League debut on Sept. 4 against the Cubs at Wrigley Field, Flynn had a no-decision.

Turner, who has struggled in the second half, will be given a couple of extra days to help get back on track. With Flynn now set for Friday, Turner will pitch the series finale on Sunday at New York.

Flynn will stay in the rotation, filling in the spot vacated when Jose Fernandez is shut down after his Wednesday start.

"Flynn will take over for Jose when he filters out of the rotation," manager Mike Redmond said. "We've set things up pretty much until the end of the season."

On Saturday at New York, the Marlins will play a doubleheader. Henderson Alvarez will pitch the first game, and Brad Hand will go in the second game.
