Wrist strain sends Dietrich to disabled list

ST. LOUIS -- Second-base depth is becoming an issue for the Marlins.

On Friday, Miami placed Derek Dietrich on the 15-day disabled list, retroactive to Tuesday, with a right wrist strain.

Outfielder Jake Marisnick was recalled from Triple-A New Orleans to fill Dietrich's roster spot.

Dietrich last played on Tuesday and went hitless in four at-bats against the Phillies. The left-handed-hitting infielder felt some discomfort taking a practice swing while on deck. He stayed in the game, but on Wednesday in the batting cage, the wrist bothered him enough to get an MRI exam, which revealed the strain.

"While in the on-deck circle taking a practice swing, he felt something," manager Mike Redmond said. "The next day, he said swinging in the cage, he took quite a few swings and it blew up on him. He got it checked out. Had an MRI, and we put him on the DL."

Dietrich opened the season as the Marlins' starting second baseman. He was optioned to Triple-A New Orleans on June 3, shortly before Rafael Furcal came off the DL. But when Furcal was placed on the DL on June 22 with a left hamstring strain, Dietrich was called back up.

Since returning, Dietrich is 4-for-28 (.143) with one double and an RBI.

For the season, Dietrich is hitting .228 with a .326 on-base percentage, with six doubles, two triples, five home runs and 17 RBIs. He's had his struggles defensively, committing 10 errors at second base, and one error at third.

Donovan Solano and Ed Lucas have been handling second base of late.

The Marlins hope to get shortstop Adeiny Hechavarria back on Monday for the series opener at Arizona.

Hechavarria (right triceps strain) went on the DL on June 25, retroactive to June 21.

The plan is for Hechavarria to play two rehab-assignment games for Class A Jupiter on Friday and Saturday, and travel to Arizona on Sunday. Barring a setback, he should be reinstated on Monday.

Redmond looks to state Marlins' case to ASG skipper

ST. LOUIS -- Marlins manager Mike Redmond plans on having a discussion with Cardinals manager Mike Matheny regarding the National League All-Star squad.

Matheny will manage the NL squad in the Midsummer Classic, set for July 15 at Target Field in Minneapolis.

Redmond hopes to lobby for a couple of his players.

"I'm just going to talk to him and see what he's got going," Redmond said. "We've got a couple of guys, for sure. Hey, we'll see how it all shakes out, but you never know."

Matheny pretty much knows how the roster is shaping up.

From a Marlins perspective, the lock to make the team is right fielder Giancarlo Stanton, who paces the NL in home runs (21) and RBIs (61). Stanton also is among the league leaders in hits (100), batting average (.313), slugging percentage (.581) and on-base percentage (.410).

The question is whether Stanton will be voted in by the fans as a starting outfielder. The 24-year-old was fourth -- behind Andrew McCutchen (Pirates), Carlos Gomez (Brewers) and Yasiel Puig (Dodgers) -- in the latest ballot update.

If Stanton isn't voted in to start, he still could be in the starting lineup as the designated hitter. But that is Matheny's call.

"I'd love to see him DH," Redmond said. "I don't know how you don't put his bat in the lineup. I would want that, probably. That's not my call. I'd like to see him play, whether it's the DH or outfield."

Redmond also plans on talking to Matheny about Casey McGehee, who paces NL third basemen in RBIs (50) and batting average (.311).

Worth noting

Tom Koehler's wife, Ashley, gave birth to a girl Thursday. Koehler, on the MLB paternity list, is still scheduled to make his start on Monday at Arizona.
