BOSTON -- The Marlins are doing little this month to buck a recent trend of superb records in May followed by subpar ones in June.

Miami entered Wednesday just 4-12 this month after setting a franchise record with 21 wins in May. Over the last three years, Miami is 51-35 in May, compared with 20-50 in June.

Manager Ozzie Guillen wasn't around for the Marlins' club-worst 5-23 record last June, but he's been caught off-guard by his team's performance this month after a red-hot May.

"It surprised me how good you can be one month and then so bad right after," Guillen said. "We know we're not performing. It's not a secret for anybody in this ballclub. Everybody who wears this uniform knows we're not performing."

The Marlins are averaging 2.50 runs per game in June and have lost 11 of their past 13 games. Still, Guillen believes his club can turn it around.

"The energy is there, the effort is there, we just can't get it done," the manager said. "I'm not going to turn my back on these guys. Nope. We're not playing good but we're good. We've got talent. I think I believe in this ballclub. There's a lot of guys we think could have a better year or better month, they're not doing it."

Miami entered Wednesday's game vs. the Red Sox with a 33-34 record. It's the first time the team has been below .500 since May 5, when it was 13-14.

Guillen has been in constant contact with owner and CEO Jeffrey Loria, but the manager doesn't think the Marlins need a shakeup just yet.

"Yeah, I talked to Jeffrey, I talk to everyone, maybe too many times," Guillen said. "But what are they going to do? I just say stick with it. It's still early. I always say you don't win the pennant race in April, May and June, but you can lose it. We've got to believe in what we have.

"What are we going to trade a guy? When you trade one guy to help, how about the rest of the eight [starters]? We can't trade eight guys. I think everybody here has talent. I think everybody here has done it before. And I think everybody here will come out of this."

Stanton OK after getting hit on hand in opener

BOSTON -- Giancarlo Stanton was back in the Marlins' lineup for Wednesday's game vs. the Red Sox after he was hit in the right hand by a pitch in the series opener on Tuesday.

Stanton was hit by a Clay Buchholz changeup in the third inning. He walked slowly to first base, where Miami's trainers and manager Ozzie Guillen checked on the outfielder. After the game, his right hand was heavily wrapped.

With the Marlins struggling offensively, they need Stanton to remain in the lineup. He entered Wednesday hitting .273 with 14 home runs and 42 RBIs in 66 games this year.

"I feel OK," Stanton said. "If it was a fastball, [it would have been] no good."

Still, the Marlins need their right fielder to break out of his 1-for-16 slump on the current six-game road trip. He went 1-for-3 with a run scored in Tuesday's 7-5 loss. In the seventh inning, Stanton had a chance to start a rally with Jose Reyes on third and one out, but he lined out to short left and Reyes was unable to tag and score.

It was just the latest in a string of missed opportunities for Miami. The club is hitting .241 with runners in scoring position and less than two outs.

"We've got problems," Guillen said. "I'm not going to deny it. The problem I think we have right now is with men in scoring position we're very bad. We're not just OK but very, very bad and that doesn't help."

Stanton hit third in Guillen's lineup on Wednesday for the fifth time this season. He was hitting .259 with runners in scoring position this year.

"You get a tendency to change lineups and do this and do that, from experience that doesn't work," Guillen said. "Oh, let's put this guy first, let's put this guy last and at the end of the day you go back home with a loss. I've got to stick up for the guys, got to believe in them, got to make the same lineup if I can to make sure they know we're behind them. I'm going to protect them and be behind them 100 percent."
