Yelich returns from DL, Jennings recalled

MIAMI -- A core player is back in the lineup for the Marlins.

As expected, the club on Sunday reinstated Christian Yelich from the 15-day disabled list. The team also recalled lefty reliever Dan Jennings from Triple-A New Orleans.

The two moves set the 25-man roster after outfielder Jake Marisnick and right-hander Anthony DeSclafani were optioned to New Orleans.

Yelich went on the disabled list with a lower-back strain on June 16, retroactive to June 14.

"It was a very slow 15 days," the 22-year-old said. "It's good to be back out there and trying to help the team win."

Yelich basically dealt with back spasms, and he returned on the first day he was eligible to be reinstated.

Yelich started the series finale on Sunday against the A's in center field, because Marcell Ozuna was given an off-day after experiencing a right leg cramp.

In his first at-bat on Sunday, Yelich tripled and came around to score on an errant throw that got past Josh Donaldson as the speedy outfielder slid into third.

Ozuna says he is fine, and with Monday being a day off, he should be back in the lineup.

Yelich, back in the leadoff spot, is hitting .259 with a .342 on-base percentage in 63 games.

His lower back grabbed on him after fielding a routine single to left field on June 13 against the Pirates. He played one inning that game, before exiting.

"It's one of those things you've got to take it slow," Yelich said. "You probably take a couple of extra days to make sure there are no lingering effects. I'm definitely glad it's over with."

Yelich appeared in four rehab assignment games, two with Class A Jupiter and two with Triple-A New Orleans, before being reinstated.

When he returned to Miami on Saturday afternoon, he was a little bit empty handed. New Orleans was playing in Nashville, and Yelich checked a bag that included his glove and a Zephyrs cap. When he arrived in Miami, and opened his luggage, the glove and cap were gone.

As a replacement, Marisnick left Yelich his glove.

Marisnick's glove has his nickname, "Big Fudge" inscribed on the side.

Jennings adds a fresh arm to Miami's bullpen, which has logged 20 innings over the last three days.

The lefty is 0-1 with a 0.86 ERA with the Marlins this season.

Mathis nabs Punto with crafty pick-off throw

MIAMI -- Jeff Mathis saw an opening and seized it with a crafty pick-off throw that nabbed Nick Punto at first.

In the fifth inning of the Marlins-Athletics game at Marlins Park on Sunday, Punto slapped a one-out single to center off Andrew Heaney.

The Marlins were keeping a watchful eye on Punto at first. Heaney made a throw over with the left-handed-hitting Stephen Vogt at the plate.

Seeing Punto off the bag, Mathis countered by executing a perfect throw to Jeff Baker at first base for the out.

"It's just something I'm always looking for, an aggressive secondary [lead]," Mathis said. "I'm just glad to get an extra out."

It wasn't just any throw.

From his squatting position, Mathis used Vogt to shield Punto's view. The behind-the-batter throw was perfect, and Baker applied the tag for the undisputed out.

The next play, Vogt grounded to third, ending the inning.

Stanton confirms Home Run Derby plans

MIAMI -- Marlins right fielder Giancarlo Stanton confirmed on Sunday that he will finally make his Home Run Derby debut.

The 24-year-old, who leads the National League with 21 homers and 60 RBIs this season, was supposed to participate in the contest as part of Matt Kemp's National League squad in 2012. But he had to back out when some loose bodies were found in his right knee, causing him to undergo arthroscopic surgery the day before the Derby.

The Gillette Home Run Derby will take place at Target Field in Minneapolis on Monday, July 14, a day before the All-Star Game.

Stanton, who has been known to hit tape-measure shots, should be able to put on a great display of power for fans. His homers are traveling an average of 422.6 feet this year, according to ESPN Stats and Info. His longest one sailed 484 feet on April 4 against the Padres.

Even though Trout has surpassed the Marlins slugger this year, no one has hit a moonshot farther than Stanton since Aug. 12, 2012, when he drove a ball 494 feet in Colorado.

Stanton's power has also allowed him to hit the third-most homers in the Majors since his debut on June 8, 2010. He's hit 138 round-trippers, which trails only sluggers Miguel Cabrera (152) and Jose Bautista (149).

Although his participation in the Derby has been long awaited by fans, Stanton hasn't allowed himself to get too excited about it. The Marlins were 3-7 in their last 10 games before Sunday's series finale against the Athletics.

"I'm not worried about it at all at this point," Stanton said. "We've had a rough couple of games so it's the last thing on my mind."

National League captain Troy Tulowitzki confirmed Saturday afternoon that Stanton would be participating. In fact, Stanton was one of the first players Tulowitzki contacted after he was named captain on Monday. There are still three spots open on the five-man team, but no word yet about who will fill them.

When Stanton's first brush with the Home Run Derby occurred in 2012, he'd hit 19 homers in the first half that year. He received an invitation to the All-Star Game to show for his efforts, but his surgery prevented him from participating in the festivities.

Despite being the fourth player in Marlins history to hit 20 or more homers and knock in 60 or more RBIs in the first half, Stanton is currently fourth among the top three vote-getters for starting outfield spots in the All-Star Game.

Two fans receive treatment after being hit by foul ball

MIAMI -- There was an eight-minute delay in the seventh inning at Marlins Park on Sunday after a female fan was struck in the face by a foul ball.

According to the Marlins, the woman was taken to a local hospital for further evaluation. There was no further report.

The incident was one of at least two situations where foul balls hit fans.

In the eighth inning, another fan was hit in the shoulder on a Craig Gentry foul that landed higher in the stands. Paramedics sent him to first aid at the ballpark, but he was released.

The more serious situation came when Nick Punto fouled off a Dan Jennings pitch in the seventh. Punto pulled a 93-mph fastball down the first-base side and into the second row of the stands. The female fan was hit in the face with the ball and was eventually taken out of the stands in a wheelchair. She left with paramedics out of the back entrance in right field.

Jennings struck out Punto on the next pitch for the first out of the inning and retired the next two batters in order.

Marlins manager Mike Redmond said that from his vantage point, it looked like the line drive ricocheted before hitting the woman.

"I couldn't really tell," he said. "I think she had sunglasses on but I couldn't tell if it hit her in the cheek or the eye, but it was square on and she had no idea it was coming. I think she just turned at the last second."

Worth noting

• According to the Elias Sports Bureau, the Marlins are the first team in MLB history to lose five or more 13 or 13-plus inning games in a calendar month.
