McGehee has All-Star numbers, needs votes

MIAMI -- The numbers make the argument.

Casey McGehee paces National League third basemen in RBIs (48), batting average (.309), on-base percentage (.374) and fielding percentage (.981).

What the Marlins' third baseman lacks is votes to represent the NL in the All-Star Game.

Milwaukee's Aramis Ramirez led the most recent fan voting. Todd Frazier of the Reds has also enjoyed a strong season, belting 17 homers and driving in 46 runs.

McGehee and right fielder Giancarlo Stanton, fourth on the latest list, are the position players who have made the strongest cases to represent Miami.

Stanton leads the NL in homers (21) and RBIs (60), but is not currently among the top three vote-getters for starting spots.

Marlins option Marisnick, DeSclafani to Triple-A

MIAMI -- Following Saturday's second 14-inning game in three days, a 7-6 loss to the A's, Marlins manager Mike Redmond announced the demotions of outfielder Jake Marisnick and starter Anthony DeSclafani.

Christian Yelich will return to the lineup on Sunday, and to accommodate him, the Marlins had to option outfielder Marisnick to Triple-A New Orleans. DeSclafani will also return to New Orleans, but a corresponding move has not been announced.

Yelich, who went 1-for-9 with four RBIs, five strikeouts and a homer in two rehab starts with New Orleans, has been on the 15-day disabled list since June 16. He suffered a lower back strain in the first inning on June 13 against the Pirates, when he fielded a leadoff single.

The 22-year-old is batting .259 with a .342 on-base percentage with the Marlins this season.

DeSclafani made three starts after he was recalled from New Orleans on June 16. He went 0-1 with a 9.00 ERA and struck out eight while allowing a .346 average against him.

Since the bullpen has thrown 20-plus innings in the last three days, a reliever is expected to be recalled in DeSclafani's stead.

Marisnick, who joined DeSclafani in the flurry of nine roster moves made on June 16, played in 13 games, including 10 starts. While he impressed with his arm, the center fielder's bat lacked luster as he hit just .170 and struck out 18 times.

Marlins recall reliever Dyson as Ramos rests

MIAMI -- Manager Mike Redmond is staying away from Marlins reliever A.J. Ramos -- but it's not because of any injury.

Ramos threw a career-high 50 pitches in 1 2/3 innings in Thursday's 14-inning game against the Phillies. The most Ramos had thrown in a single game this season was 33 in one inning on June 15, so he's getting the chance to rest his arm.

The right-hander, who has appeared in 39 games this year, likely won't be available in this series against the Athletics.

To fortify the bullpen, the Marlins have recalled another fresh arm from the Minor Leagues, this time Sam Dyson from Triple-A New Orleans. Dyson was called up earlier this month when starter Nathan Eovaldi went on the paternity list. In a single outing, he threw 1 1/3 innings and recorded his first big league win against the Cubs. He was optioned back to New Orleans following the game.

Dyson, ranked as the Marlins' No. 13 prospect, is the second pitcher called up in as many days, and he will be taking the spot of Brian Flynn, who returned to New Orleans after Friday's game. Flynn, the club's No. 6-ranked prospect, joined the team right before the opener against the A's and immediately threw three innings in relief of starter Anthony DeSclafani.

Yelich to be back in LF upon return; Ozuna to CF

MIAMI -- When Christian Yelich comes off the disabled list on Sunday, the Marlins anticipate returning to the status quo.

Manager Mike Redmond had considered perhaps going with Yelich in center field and using Marcell Ozuna in left field. But after assessing everything, Redmond on Saturday said he plans on returning Yelich to left and Ozuna will go to center.

"I know O's arm plays better in left, but I like O in center," Redmond said. "That's not to say we won't mix and match as well."

Yelich is capable of playing left or center, but Ozuna has the strongest outfield arm in the organization.

Yelich went on the disabled list on June 16 with a lower-back strain. The 22-year-old was feeling much better a couple of days after tightening up, and he played two rehab assignment games with Triple-A New Orleans on Thursday and Friday night, before returning to Miami on Saturday.

Yelich, batting .259 with a .342 on-base percentage, will return to the leadoff spot now that Rafael Furcal is out indefinitely with a left hamstring strain.
