Stanton on cusp of rejoining Marlins from DL

NEW YORK -- The biggest threat in the Marlins' organization is about to rejoin the club.

Giancarlo Stanton, the 23-year-old slugger, could be joining the team on Monday for the series opener against the Brewers at Marlins Park.

On the disabled list since April 30 with a strained right hamstring, Stanton is wrapping up his rehab assignment with Class A Jupiter.

"Stanton is any day," Marlins manager Mike Redmond said.

The Marlins, last in the Majors in runs scored with 179 entering Sunday, are eager for Stanton's presence. Even though he is off to a slow start, batting .227 with three home runs and nine RBIs, he is one of the most feared power hitters in the game.

"As a manager, to have him in the lineup, even if he takes, he's probably going to walk a couple of times," Redmond said. "Even if he just stands there, that's a great presence to have in our lineup. I feel comfortable, if he feels like he's ready to go, he's ready to go. We'll see. We've got to be smart, and make the right decision."

The Marlins on Sunday welcomed back first baseman Logan Morrison, who opened the season on the 60-day disabled list after undergoing right knee surgery last September.

"Some guys feel like they need to have an extended rehab assignment," Redmond said. "In LoMo's situation, he was out for such a long time. It was important for him to go down there and show that he is healthy and feeling good. He really needed the at-bats, without having a Spring Training.

"Stanton, he's had at-bats. It was more of him feeling healthy, feeling comfortable, with his hamstring and his body."

Marlins reflect on Saturday's record marathon win

NEW YORK -- Those who waited out Saturday's marathon witnessed the longest game in Marlins' history.

In 20 innings, the Marlins edged the Mets, 2-1, in an endurance test that lasted six hours and 25 minutes.

Time-wise, it was a team record, surpassing what took place at Sun Life Stadium in Miami on April 27, 2003. That afternoon, the Marlins lost 7-6 to the Cardinals in 20 innings and six hours and seven minutes.

Juan Pierre played all 20 innings in 2003, and the veteran was in the lineup for 10 innings on Saturday.

"It was a little bit better because we got the W," Pierre said of Saturday. "Last time, I played all 20 innings. [Saturday] felt like a day off. I played 10 and sat out 10. It's like a day off."

Miami manager Mike Redmond actually started for the Marlins in their 20-inning loss 10 years ago, while hitting coach Tino Martinez started at first base for the Cardinals, and he went 5-for-8 in his team's victory.

In exhausting games, players battle through mental and physical fatigue.

"Once you get around 14 or 15 innings, all the rah-rah stuff is gone," Pierre said. "It's just, 'Getting it done.' We don't need to hear any more, 'Let's go! Come on!' Everybody knows what we've got to do."

Redmond says players tend to press.

"After about nine or 10 innings, you get mentally tired and physically tired," Redmond said. "You just want it to end. Sometimes, guys want it to end so badly, they end up trying to do too much. You end up playing 20 innings."

Worth noting

• First baseman Casey Kotchman was not available on Sunday because of soreness in his right rib cage. Kotchman, 0-for-20 on the season, was reinstated from the 60-day disabled list on June 3. He was out with a strained left hamstring.

• Kevin Slowey threw seven innings of relief in the Marlins' 20-inning, 2-1 win over the Mets on Saturday. Initially, Slowey was scheduled to start on Tuesday. Instead, he is being flipped with Jacob Turner. Now, Turner will face the Brewers on Tuesday, and Slowey will go on Wednesday at Marlins Park.

• Ed Lucas, who hadn't played left field since last June 20, caught the final out of Saturday's 20-inning game in left field. He gave the ball to Steve Cishek, who recorded the save after the six-hour, 25-minute affair.

• Nathan Eovaldi, on the 60-day DL with right shoulder inflammation, is making what could be his final rehab assignment start on Sunday for Double-A Jacksonville.
