Although he’s 2-2 for the Marlins, right-hander Nathan Eovaldi isn’t particularly satisfied with how he has done in his four starts since being traded to Miami.

“I’d just like to get past the fifth inning,” said Eovaldi, who has given up nine earned runs in 17 1/3 innings and has fewer strikeouts (10) than walks (12).

Even though Eovaldi got himself in trouble a few times in Monday’s 4-0 loss to the Phillies, catcher John Buck said he was encouraged by the adjustments the 22-year-old right-hander made.

“He’s just been a little erratic with stuff,’’ Buck said. “He’s rushing at times and kind of got out of whack [Monday]. But I liked how he was able to slow himself down in those innings when he struggled.

“It probably could have gotten ugly if he kept doing the same thing. But he made some good pitches.”

Eovaldi said what has hurt him the most is when he can’t locate his off-speed pitches.

“He’s got great stuff,’’ Buck said. “But when you can’t locate your off-speed stuff, they can just sit on your heater.

“When they see it spinning they can just shut down and wait.’’

Equal time

Rob Brantly could end up being the Marlins’ long-term solution behind the plate.

But as far as the rest of this season is concerned, manager Ozzie Guillen said Tuesday he’s going to do his best to divide playing time equally between the 23-year old rookie and Buck, who still has a year on his contract and $6 million owed to him next season.

“We’re not going to leave [Buck] on the bench,” Guillen said. “We’re going to pick a spot to play him and try to have the kid catch everyone in the rotation.

“But in the meanwhile, Buck also has to play games. He’s not going to be a backup. We’re going to figure out how to do it. It’s a little bit of a headache. But I have to respect Buck.”

Buck is hitting .303 with four RBI this month in 10 games and will likely get the start in Wednesday’s day game against the Phillies.

Ranking the catch

Giancarlo Stanton said he isn’t sure if his diving catch in right field Monday to rob Eric Kratz of an RBI is the best grab he has ever made, but said, “It’s up there.’’

“It’s either that one or the one in May [against Atlanta] to rob [ Jason] Heyward,’’ Stanton said.

Stanton said he didn’t feel any discomfort or limitations from his recently surgically repaired right knee.

“To save a potential run and to get a ball I didn’t think I could get to right off the bat is a good feeling,’’ Stanton said.
