Lee mentors Stanton on nuances of batting cleanup

MIAMI -- Becoming an accomplished cleanup hitter is a process, even for players who possess plenty of power.

Giancarlo Stanton, among the strongest in the game, is still picking up the finer points of batting in the fourth spot.

The Marlins' 22-year-old is getting some advice from veteran Carlos Lee, who had hit cleanup until the switch was made a few days ago.

"He will be fine," Lee said. "He's going to be a guy who puts up 40 [homers] and drives in 120 [runs] for a long period of time. He's still learning the game. It's part of the process. We talk a lot. I always try to help him."

Lee made a suggestion earlier in the homestand, when the Marlins faced Stephen Strasburg and the Nationals.

"I told him the other day, sometimes you've got two guys on base and you're facing a guy like Strasburg," Lee said. "It's a guy who probably won't give up a three-run homer, so you've got to find a way to get the one, the guy on third base in. Things like that. You're not always going to hit the three-run homer. Get that one in."

Lee puts a premium on RBIs. To him, a 0-for-3 day is fine if you drive in a run.

Unlike a player's batting average, which moves in either direction on every at-bat, the RBI number can only go up.

"Your RBIs never go down," Lee said.

A player like Stanton has the ability to belt a home run on any swing, which makes him one of the most dangerous players in the game. Stanton belted home run No. 30, while hitting cleanup, on Tuesday.

"He's going to be a run producer anyway," Lee said. "When you hit in the lineup with runners on base in scoring position, the idea is to drive them in."

With experience, Lee has learned to not let where he is batting in the order affect him.

"It all depends on how you take it," the first baseman said. "My idea is when I've got guys on base, the pitcher is in trouble, not me. He's in trouble. I'm OK. I've got an opportunity to drive in runs.

"[Stanton's] going to learn and figure it out a little bit more. When he does, he's going to be very dangerous. It's not like he's not dangerous right now, but there are still little things. Sometimes you've got to get one when you can't get that three."

Oviedo undergoes Tommy John surgery

MIAMI -- Marlins reliever Juan Carlos Oviedo, who sprained his right elbow in July, underwent Tommy John surgery on Thursday morning.

The procedure was performed by Dr. James Andrews, and recovery time is typically at least 12 months.

Oviedo, formerly Leo Nunez, felt discomfort a few days before his eight-week suspension was scheduled to end. The right-hander was reinstated from the restricted list on July 23, and placed on the 15-day disabled list that day.

On Tuesday, Oviedo was transferred to the 60-day DL.

Oviedo had been on the restricted list since September 2011, and he was suspended by Major League Baseball in May for playing under a false identity.

After attaining his visa in late May, the reliever returned to Florida from his home in the Dominican Republic and reported to the Marlins' facility in Jupiter, where he worked out and served his suspension before starting a Minor League rehab assignment.

The stint was cut short on July 14, when he exited an appearance for Triple-A New Orleans with soreness in his right elbow. An MRI exam revealed Oviedo had a sprained ulnar collateral ligament in his throwing arm.

From 2009-11, Oviedo had 92 saves as the Marlins' closer. The right-hander is eligible for free agency next season.

Oviedo's surgery came a day after Logan Morrison underwent a successful procedure on his right knee. Morrison tweeted that he had 10 stitches in his knee.

Six-man rotation idea a temporary one for Miami

MIAMI -- Going with a six-man rotation is only a temporary idea for the Marlins.

The team decided to go with six starters to ease the innings on rookies Jacob Turner -- who will start on Friday at Washington -- and Nathan Eovaldi, who faced Milwaukee on Wednesday.

"I'm not a fan for a lot of different reasons," manager Ozzie Guillen said. "But why we're doing it here, we've got to protect Turner, Eovaldi. Those two kids."

Using an extra starter means veterans like Josh Johnson, Mark Buehrle and Ricky Nolasco will make one fewer outing.

For Buehrle, that may determine whether he reaches the 200-inning mark for the 12th straight season. The veteran lefty has thrown 173 2/3 innings, and if he averages seven innings in his final four starts, Buehrle would finish with 201 2/3 innings.

"I talked to Buehrle about it," Guillen said. "He says he wants to have 200 innings. If we've got seven innings from Buehrle, that means we're winning the game."

In general, Guillen says it is more difficult for starters in the National League to reach 200 innings.

"The National League is harder than the American League to get to those 200 innings," the manager said. "That's no doubt. I said that early, the worst thing about the National League is getting used to taking my pitcher out at 70 pitches when we're down by one run in the sixth.

"I think it's hard to get 200 innings in the National League. You have to be a pretty good offensive ballclub to give you the opportunity. In the American League, if you're down 1-0, you're in the ninth. In the National League, you're down 1-0, in the sixth, you're gone. I tried to explain how hard it is to them. I hope they understand."
