Stanton racks up records in monster May

Slugger ties team marks with 12 homers, 30 RBIs in month

MIAMI -- More than just home runs have come at a rapid rate for Marlins slugger Giancarlo Stanton in May.

Along with belting a club-record 12 home runs in the month, Stanton has driven in a franchise-best 30 runs after his RBI single and home run against the Nationals on Wednesday.

In Miami's last game of the month, Stanton belted a homer and drove in two runs, capping one of the best overall months in team history.

Stanton connected on a home run off Washington's Ryan Perry in the seventh inning on Wednesday.

Miguel Cabrera had 30 RBIs in 2006. Stanton had previously passed Preston Wilson, who had 27 in 2000.

"It's a tribute to the guys ahead of you getting on base," said Wilson, now a pregame and postgame analyst for the Marlins on Fox Sports Florida. "It's also a tribute to when you get a home run, there are not many solo home runs. When you have a month like that, when you hit a home run, it's either a two-run or three-run homer.

"When you get guys on and you capitalize on those situations, you have a great month like that."

Stanton now shares the homer mark with Dan Uggla, who hit 12 in May 2008. Uggla drove in 26 runs that month.

The Marlins record for RBIs in any month is 33, by Hanley Ramirez in June 2009. And Cabrera had 32 in August 2006.

The May Stanton is having should make him a strong contender for National League Player of the Month.

"I don't follow who's hot or who's not," manager Ozzie Guillen said. "I doubt many have put up better numbers than him this month. Maybe somebody out there. I don't know which one. Whoever had better numbers this month better than [Stanton], he had a very good month."

Before roof can close, rain cancels BP in Miami

MIAMI -- Having a roof guarantees prompt start times at Marlins Park. But on Wednesday afternoon, batting practice was washed out due to a heavy downpour.

The roof often remains open in the morning and day time to allow sunlight onto the grass.

At about 3 p.m. ET, with several players getting early work in, it started to rain. For a few minutes, it was light, but shortly after, there was a downpour. The tarp had been placed on the infield, but the roof took a while to close, and the ballpark was doused.

Water cascaded down the steps of the Marlins' dugout, located on the third-base side. The photographer well also was flooded.

Rain created a problem in the first level of the three-level press box. Eventually, the roof closed, and the field was fine for the start of the game.

Manager Ozzie Guillen made light of the fact there was no batting practice.

"Me and the coaches are the only ones here at 2 in the afternoon to throw batting practice," Guillen said. "We get tired and sweaty. It's tough. At least we take a break. That's all I can say."

Once the roof was closed, the grounds crew got the field in playing shape.

"It should be ready, I don't see why not," Guillen said. "That roof closed very slow, and that's the reason we cancelled batting practice. It should be ready to go for the game."

The roof is regularly left open to allow sunshine and rain for the grass. When there is a threat of rain, the roof usually closes immediately.

Bonifacio hopes to be back in a month

MIAMI -- Emilio Bonifacio remains hopeful that his recovery time will be closer to four weeks than six weeks.

The Marlins center fielder underwent surgery to repair a ligament in his left thumb on Friday. He was given a four-to-six week recovery time.

Next week, Bonifacio will have the stitches removed, which means he will be able to start doing some exercises for the thumb and hand. On Wednesday, he started doing some running for the first time since the surgery.

"The stitches come out next week," said Bonifacio, who has been on the disabled list since May 20, retroactive to May 19. "Then I can start moving it and doing exercises."

Bonifacio jammed his thumb while attempting to steal second base in Cleveland on May 18. It was the only time this season he was caught stealing.

Bonifacio still leads the Major Leagues with 20 stolen bases. Now, Jose Reyes is second with 15.

Surgery went well, and Bonifacio is confident he could be back in four weeks.

"I hope," he said. "As long as I have a full recovery and it's strong."
