Marlins not sellers, gaining confidence in rotation

MIAMI -- Fresh off a 6-1 road trip, the Marlins haven't explicitly said they're staying put at the non-waiver Trade Deadline, but they have confirmed they're not sellers.

"I would say you can take us out of the sellers category," said Michael Hill, Miami's vice president of baseball operations. "We're just looking for ways to build on what has been a very positive year for us."

Though the Marlins won't turn down help for their starting rotation, they are more confident in the guys they're trotting out to the mound every day.

Brad Hand and Jacob Turner were a combined 3-0 with a 1.50 ERA in 18 innings during the Marlins' road trip, something that has manager Mike Redmond feeling a lot more secure about the revolving door at the back end of the starting rotation these past few months.

"When you talk about getting on a roll and winning games, the first thing, at least for me, and probably most managers would say the same thing, is how the pitching is," Redmond said. "And our pitching's been really good. I feel great when our guys go out there."

Closer Steve Cishek has received his fair share of attention recently, Hill said, especially since he mounted such a stellar week (five saves, 1.80 ERA) that he was named the co-National League Player of the Week on Monday.

But the 28-year-old, who admitted to checking trade rumors online once "when I was bored," was adamant about remaining a Marlin.

"I love it here, I love the guys," Cishek said. "I think what we're doing here is amazing. Meaningful games obviously keep your interest. I just love the direction the team's going. [But] it's out of my control. Whatever happens, happens."

Marlins recall Marisnick, send down Realmuto

MIAMI -- The Marlins optioned catcher J.T. Realmuto to Double-A Jacksonville on Monday, making room for the return of outfielder Jake Marisnick to Marlins Park.

Marisnick, whose most recent stint with the club was in early July (though he didn't play), was hitting .278 with 40 RBIs in 88 games with Triple-A New Orleans this year. Facing Triple-A pitching, he racked up 16 doubles, four triples and 10 homers. He also stole 24 bases.

The speedy outfielder played 13 games with the Marlins in mid-June and went 8-for-47. In his last 20 games with the Zephyrs, Marisnick was on a tear, batting .330 with five doubles, a triple, four homers and 13 RBIs. He'd also reached base safely in 18 straight.

However, unlike in June when Marisnick was up to cover for an injured Christian Yelich, Marlins manager Mike Redmond expects to use Marisnick more as an extra pair of legs.

"Jake brings us just another option if we need a pinch-runner or just a guy defensively. ... He can steal a base," Redmond said.

Realmuto was recalled from Double-A Jacksonville on Friday, but he did not make an appearance this past weekend in Houston. He's hitting .301 and has driven in 46 runs for Jacksonville this season.

Injury roundup: Dietrich begins taking swings

MIAMI -- The contingent of Marlins players on the disabled list is still a ways removed from slimming down.

Closest to returning is second baseman Derek Dietrich, who landed on the disabled list July 4 with a sprained right wrist. He started taking grounders and was supposed to begin work in the batting cage on Monday at Marlins Park.

Manager Mike Redmond said Dietrich might go on a rehab assignment by the end of the homestand -- but that all hinges on how well he does with his swings.

Reliever Carter Capps (right elbow sprain) began his throwing program and is already long-tossing. Redmond doesn't know when he'll start throwing bullpen sessions, but it might be while the team's in Miami this week.

"I don't know," Redmond said. "I don't have a date but sooner than later."

Once he progresses to that stage, Capps, who's been on the 60-day disabled list since the end of May, should be about a month away from a return to the big leagues.

Kevin Gregg has also made strides since being placed on the 15-day DL with right elbow inflammation on July 18 (retroactive to July 14), as the righty reliever is playing catch again.

Although nothing new is known about Rafael Furcal's recovery from a left hamstring strain that sidelined him June 22, at least Jose Fernandez was back at the ballpark, in uniform and smiling.

The right-hander underwent Tommy John surgery in May and likely will not be back until next year's All-Star break.

When asked when he'd be returning, Fernandez laughed and answered, "Uniform's on."
