Jennings heads home, will rest up on concussion DL

CINCINNATI -- The prognosis is encouraging for Marlins reliever Dan Jennings, who sustained a concussion after being struck on the left side of the head by a line drive on Thursday night at PNC Park.

The lefty reliever was discharged from a Pittsburgh hospital on Friday, and he was cleared to fly to South Florida.

Jennings tweeted: "Headed home to rest up with my family. Thanks again everyone for the kind words."


The Marlins on Friday placed Jennings on the seven-day concussion disabled list. But that doesn't mean he automatically will return in a week. If he needs more time, he can be transferred to the 15-day DL.

Jennings received a scare in the seventh inning of the Marlins' 7-2 loss to the Pirates on Thursday. Jordy Mercer's comeback liner deflected off the left side of the reliever's head.

Jennings also expressed his thanks to Mercer for his concern.

Via Twitter, the reliever wrote: "Also thanks to @jordy_mercer for reaching out, class act."

A CT scan taken Thursday night came back negative.

"Everything checked out fine," Miami manager Mike Redmond said. "It's good news he was cleared to fly back home. It tells a lot about how he's doing. He will get home and rest. We will monitor and know more when we get back to Miami.

"We definitely feel that he made it through a scary situation. It looks like he will be fine and make that full recovery."

Marlins land pair of Minors relievers for Turner

CINCINNATI -- The Marlins acquired a pair of Minor League pitchers on Friday afternoon in exchange for right-hander Jacob Turner.

Right-handers Jose Arias and Tyler Bremer were obtained from the Cubs for Turner, who was designated for assignment on Tuesday.

Both sides were expected to complete the deal after Chicago claimed Turner off waivers on Wednesday.

Arias and Bremer have been assigned to Class A Greensboro. Both have had experience closing, while Arias has also done some starting.

The Marlins were in a precarious spot keeping Turner because the 23-year-old is out of Minor League options. He had struggled as a starter and in relief, posting a 4-7 record with a 5.97 ERA in 20 appearances, 12 of them starts.

"The Cubs were the club awarded with the claim," Marlins president of baseball operations Michael Hill said. "They had exclusive negotiating rights for his services. We just wanted to get as much quality as we could in the trade. We got two very good, young arms to help replenish the system."

Arias was 1-1 with a 1.77 ERA and three saves for Class A Kane County, striking out 51 batters in 25 relief appearances.

Bremer also began his season with Kane County, going 5-1 with 12 saves and a 2.43 ERA in 28 relief appearances, with 51 strikeouts. He was promoted to Advanced Class A Daytona in the Florida State League at the end of June and was 0-1 with a 4.70 ERA and 12 strikeouts in eight appearances.

Had Miami not finalized a deal with the Cubs, it could have pulled Turner back off revocable waivers and placed him on release waivers. In that scenario, Chicago would have run the risk of not being able to land Turner.

The team with the worst overall record would have had first choice. The Rangers and Rockies could have both been ahead of the Cubs.

Before the July 31 non-waiver Trade Deadline, the Marlins didn't shop Turner, because at the time, the club was seeking its own trade options. Miami ended up acquiring Jarred Cosart from the Astros, and the team attempted to land another starter, but a deal couldn't be completed.

"[Turner] was a name we had discussed," Hill said. "But it wasn't something we considered at the time, because we hadn't acquired Cosart yet. We were still allowing [Brad] Penny to pitch [in the Minors]. We didn't have the depth. We still wanted [Andrew] Heaney and [Justin] Nicolino to start in the Minor Leagues.

"Leading up to the Trade Deadline, if the right deal would have been there, it would have been something we would have considered. The right deal just never came up."

Hernandez down, Lucas up in flurry of moves

CINCINNATI -- At some point, the Marlins envision Enrique Hernandez as being an everyday player in the big leagues. For now, the 23-year-old will be given more regular playing time in the Minor Leagues.

Hernandez was optioned on Friday to Triple-A New Orleans on a busy transaction day for Miami, which also optioned lefty Brian Flynn to New Orleans and placed reliever Dan Jennings on the seven-day concussion disabled list. Infielder Ed Lucas, right-hander Anthony DeSclafani and lefty Edgar Olmos were recalled from Triple-A.

After the Marlins' 2-1 win over the Reds on Friday night, the club announced that Olmos was optioned back to New Orleans and Brad Penny was called up from there to start Saturday night's game at Great American Ball Park.

The Marlins acquired Hernandez and right-hander Jarred Cosart from the Astros on July 31 for prospects Jake Marisnick and Colin Moran.

Hernandez, however, hadn't been getting regular playing time with Jordany Valdespin and Donovan Solano playing a majority of the time at second base.

In four games, Hernandez was hitless in seven at-bats.

At New Orleans, he will see a majority of his time at second base. But he will also see action at third base and the outfield.

"He's still a young guy, and he needs to play every day," manager Mike Redmond said. "It's tough. I talk about it a lot: Young guys coming to the big leagues and sitting on the bench. It's tough. A lot of them are not conditioned for that role. They're used to playing every day."
