Home runs have been an issue for Cishek this year

PHILADELPHIA -- When things are going wrong, everything tends to get magnified.

Marlins closer Steve Cishek witnessed that in Tuesday's 7-3 loss in 11 innings to the Phillies at Citizens Bank Park.

After Miami took a 3-2 lead in the 10th inning, Cishek tried to close out his sixth save. Instead, he was tagged with his second blown save in seven opportunities.

Cishek surrendered a leadoff, game-tying home run to John Mayberry Jr., who belted a 2-2 slider over the wall in center field. In the 11th, Mayberry struck again with a walk-off grand slam off lefty Edgar Olmos.

Cishek has been hurt a few times by the long ball this season. The home run was the third he's allowed in 24 innings. In 2012, he gave up three home runs in 63 2/3 innings.

"It's tough. Your team is relying on you to put that game away," Cishek said. "They fought so hard, and it's in your hands to get three outs right then and there to shut the door."

Prior to Tuesday's home run, Cishek had been getting back on track.

After posting a 5.25 ERA in April, the right-hander's ERA was 3.48 in May, with three of the four runs he allowed coming on May 16 in a 1 2/3-inning outing against the Reds.

"In his last couple of outings, he had been really good," manager Mike Redmond said. "He just threw what looked like a flat slider there, and [Mayberry] just crushed it. That's the way things have been going."

Pierre wants Marlins to build off early struggles

PHILADELPHIA -- If the youthful Marlins learn from the mistakes of today, they should enjoy a brighter tomorrow.

That's a message veteran outfielder Juan Pierre is delivering to the club.

"These are the days when everybody is counting you out," Pierre said. "On the road, fans are saying, 'You're the worst team in baseball.' You remember these times, and you don't want to feel them again. I think it makes you strong, especially guys who are struggling for the first time, guys going through 1-for-15 stretches like that."

The Marlins are enduring their share of growing pains, suffering tough losses since the season opened.

Like the rest of the team, Pierre also has had his struggles -- batting .238 with a .296 on-base percentage. He has been stringing together better at-bats of late, entering Wednesday with three straight two-hit games. And in his last 10 games, he is hitting .270.

"You just have to stay after it," Pierre said. "Just like when it seems like there is no tomorrow, and you keep losing, then the turning point will happen. You just have to have that trust and faith."

The losing is draining, but it hasn't deterred Pierre's unrelenting work ethic.

"It's frustrating coming in everyday when you put in all the work and it seems like you're accomplishing nothing," Pierre said. "I remember my first time going through this type of deal has definitely made me stronger for times like this, meaning, not to panic and stuff."

Quiet by nature, Pierre is finding himself talking more this year to players.

"Younger guys are asking questions, which is good," he said. "I'm not the type who goes into lockers and says stuff. I'm able to share. But I'm going through it, too. It ain't like I'm batting .350. I'm in the same boat as the younger guys.

"Hopefully, they see that I go out and prepare every day, whether I'm 0-for-20 or 10-for-20. It doesn't change. Hopefully, they can take that one thing from watching me. You just have to get your work done."

Eovaldi to make one more rehab start before return

PHILADELPHIA -- Plans to reinstate Nathan Eovaldi to the Marlins' rotation next week have been pushed back a little bit.

Eovaldi, recovering from right shoulder inflammation, will be getting one more rehab start for Double-A Jacksonville before being reinstated from the 60-day disabled list.

Initially, the Marlins were leaning toward making Eovaldi's start on Tuesday night his last at Jacksonville. But after he threw 86 pitches in 4 2/3 innings, the organization decided not to rush the right-hander.

Physically, Eovaldi is fine. His fastball was at 95 mph on Tuesday. But he had a rough first inning, giving up three runs while throwing about 30 pitches against Mobile.

Eovaldi has made three rehab assignment starts, with his first two at Class A Jupiter.

Yelich headed to Minor League disabled list

PHILADELPHIA -- Marlins prospect Christian Yelich will be placed on the Minor League disabled list on Thursday with a small abdominal wall strain.

The 21-year-old is expected to miss about two weeks.

Ranked by MLB.com as the Marlins' top prospect, Yelich is batting .262 with six home runs and 28 RBIs in 41 games for Double-A Jacksonville.

Yelich was injured while making a diving attempt in the outfield on Sunday. He played on Monday, and was lifted after three at-bats.

The Marlins had been weighing promoting Yelich to the big leagues, perhaps as early as next week.

Worth noting

• Chris Coghlan, who had a 10-game hitting streak snapped on Tuesday, was given Wednesday off to rest a sore calf. Coghlan was available off the bench. But with the team off on Thursday, it allows Coghlan to get a two-day breather.

• Giancarlo Stanton, recovering from a strained right hamstring, was back in the starting lineup for Class A Jupiter on Wednesday. Stanton played five innings in right field for the Hammerheads and went hitless in three at-bats in Game 1 of Tuesday's doubleheader. There still isn't an exact target date for Stanton to be reinstated from the 15-day disabled list.

• Placido Polanco was not available on Wednesday because of a virus that has kept him out of the starting lineup for all three games at Philadelphia.
