The Miami Marlins said Sunday that slugger Giancarlo Stanton is likely done for the season with a left groin injury, opening the door for Alex Rodriguez to possibly help his hometown team make the playoffs.

President of baseball operations Michael Hill said the Marlins are discussing whether to reach out to Rodriguez, who was unconditionally released by the New York Yankees on Saturday.

"We're going to look at everything," Hill said. "There has been information out there about his situation. I have no idea what his interest level is to continue playing. He has something set up to move into the Yankees front office; I don't know where his head is on that."

The 41-year-old Rodriguez, who grew up in South Florida and still lives there, was batting .200 this season, but he had 33 homers and 86 RBIs last season.

The Marlins put Stanton on the disabled list earlier Sunday, and manager Don Mattingly said after Miami's 5-4 win over the Chicago White Sox that the MRI on Stanton revealed something serious and that he wouldn't play again this season. This would be the third straight year in which Stanton's season has been cut short because of injuries.

Hill said Stanton is out at least six weeks, so there is a remote chance he could return.

The team also put left-hander Adam Conley on the DL with finger tendinitis in his pitching hand.

The Marlins are a half-game behind the St. Louis Cardinals for the second wild card as of Sunday night.

Stanton was injured Saturday, when he made an awkward slide while trying to stretch a single into a double in the ninth inning against the White Sox. He was tagged for the final out of the game and was slow to rise. He finally limped off the field as the White Sox celebrated an 8-7 victory.

Stanton Likely Out For Season After Giancarlo Stanton strained his groin Saturday, the Marlins placed the right fielder on the 15-day DL, but he is likely out for the season, according to the organization. Stanton ranks first on the Marlins in home runs (25), RBIs (70), slugging percentage (.496) and walk rate (10 percent). But in his absence, others have stepped up, as Miami is 11-3 without Stanton this season.

"He looked like he got shot," Mattingly said. "You just see the leg give out. Obviously it's not a very good sign when you see that. Hopefully he's out a couple of weeks and we get back at it. If not, we've got to do what we've got to do."

Stanton, this year's Home Run Derby winner, leads the Marlins with 25 homers and 70 RBIs while batting .244. Justin Bour, who has 15 home runs, is sidelined with an ankle injury, creating a void at first base that Rodriguez could help fill.

The Marlins are contending for their first playoff berth since 2003. To overcome the loss of Stanton, Hill said, the front office will consider all options -- including Rodriguez.

"This team has played too well for too long," Hill said. "We're right in the thick of this thing, and we're going to do everything in our power to help in any way we can. If it's him, if it's someone else, we're going to try to find a way to make it happen.

"We're putting together our list of options. He's an available player, so he'll be on that list, and we'll see where it goes."

Rodriguez needs only four homers to become the fourth player to hit 700, and the looming milestone might lure him into continuing his 22-year career. But he hasn't played much in the field since 2013, complicating any role he might have with a National League team.

Conley gave up five runs in four innings Saturday and said he has been dealing with soreness in his pitching hand that has been getting worse. He hurt his hand banging it on the roof of the dugout at Wrigley Field celebrating a teammate's home run on Aug. 3.

The injury was diagnosed as tendinitis. Mattingly said it would likely force Conley to miss a turn, so the Marlins decided to put the youngster on the DL to give him a breather. Conley is 8-6 with a 3.94 ERA in 24 starts.

Infielder Robert Andino and reliever Hunter Cervenka were called up from Triple-A New Orleans.
