Sanabia sent to DL; reliever Jennings called up

ST. PETERSBURG, Fla. -- As expected, the Marlins on Monday placed right-hander Alex Sanabia on the 15-day disabled list with right groin weakness.

Replacing Sanabia on the roster is lefty reliever Dan Jennings, who was recalled from Triple-A New Orleans.

The team is weighing who will take over Sanabia's spot in the rotation, which next comes up on Friday at home against the Mets.

Manager Mike Redmond on Monday said Wade LeBlanc, who opened the season in the rotation before being moved to the bullpen, is an option.

Redmond ruled out Nathan Eovaldi, who is on the 60-day disabled list with right shoulder inflammation. Eovaldi threw a rehab assignment game at Class A Jupiter on Saturday.

"Right now, he's scheduled to make two more starts down in the Minor Leagues," Redmond said. "We've got to make sure he is built up properly, and is feeling good before he comes back to the big leagues."

Injuries keep piling up for the Marlins, who currently have 12 players on the disabled list.

Sanabia threw four innings and gave up four runs in Sunday's 5-3 setback against the White Sox. Immediately after the game, he told reporters that he would be heading to the disabled list.

Sanabia has dealt with a sore groin since his start early in the month at San Diego. The right-hander is 3-7 with a 4.88 ERA.

Because the Marlins won't need another starter until Friday at home against the Mets, the team called up a reliever. Jennings, 26, is 3-2 with a 1.80 ERA for New Orleans. He has a 0.68 ERA in his last 10 outings.

Jennings, who has always relied heavily on his slider, attributes some of his success in New Orleans to fastball command.

"I'm able to throw my fastball on any count, and working both sides of the plate," Jennings said. "I've been able to throw my fastball better than I have in the past."

Coghlan reflects on Memorial Day as league honors vets

ST. PETERSBURG, Fla. -- Before heading to the ballpark on Monday, Marlins outfielder Chris Coghlan had the privilege of eating breakfast with his brother, Kevin.

A former Marine, Kevin served two tours of duty in Iraq, and he is now graduating from college.

Spending time with family is always special for Coghlan, who is from the Tampa Bay area. Adding to the occasion was the fact his family was together on Memorial Day.

Major League Baseball paid tribute to veterans in several ways on Monday. Every team, including the Marlins, wore camouflage caps and jerseys with camouflage lettering. The digital camouflage design was licensed from the United States Marine Corps. The Marlins and Rays also participated in the National Moment of Remembrance by holding a moment of silence at 3 p.m. prior to the game.

"I think Major League Baseball does a great job of setting aside time and making it a point to remember those who have fought for our freedom," Coghlan said. "I got to see my brother today before he went on a cruise to celebrate his graduation."

Chris has also done his part to recognize those in the armed services. Prior to the 2010 season, the 2009 National League Rookie of the Year was part of a contingent of Marlins players and front office executives to visit troops overseas.

"It was good to see my brother this morning," Coghlan said. "I'm happy for him and proud of him."

Morrison eyes return to Marlins in early June

ST. PETERSBURG, Fla. -- Stage two of Logan Morrison's rehab stint is set to take place on Tuesday at Double-A Jacksonville.

An exact target date for Morrison's return to the Marlins is not set, but it could be around June 10.

Morrison is recovering from right knee surgery, and he opened the season on the 60-day disabled list. Technically, he is eligible to be reinstated on Thursday, but manager Mike Redmond said on Monday that he will need more time.

The 25-year-old first baseman began his rehab stint on May 20, and position players are allowed 20 days on assignment.

Because Morrison has not played in the big leagues since last July, he is striving to get as many at-bat as possible. His assignment ends on June 9, the final day of Miami's road trip at the Mets.

"We want to get him as many at-bats as we can," Redmond said.

Redmond added that Morrison may need the entire stint.

Morrison started off his rehab assignment at Class A Jupiter, where he has played for a week.

Worth noting

• Donovan Solano, on the disabled list with a left intercostal strain, is scheduled to head to Jupiter this week, where he will be eased into games.

• Giancarlo Stanton, on the 15-day disabled list with a strained right hamstring, has began light running. The All-Star right fielder has already been throwing and hitting, but the real test is running. There is no timetable for his return.
