Dietrich, drafted by Rays, happy to be with Marlins

ST. PETERSBURG -- Picked by the Rays in the second round of the 2010 First-Year Player draft, Derek Dietrich once believed he would be someday making his big league debut with Tampa Bay.

It didn't work out that way, but the 23-year-old couldn't be happier.

Traded to the Marlins on Dec. 4 for Yunel Escobar, Dietrich now finds himself starting at second base and hitting third.

Injuries to Donovan Solano and Chris Valaika led to Dietrich getting called up from Double-A Jacksonville to Miami on May 8.

Dietrich is making the most of his opportunity. He's hitting .238 with three homers and eight RBIs in 63 at-bats, including an RBI triple in Tuesday's 7-6 loss to the Rays.

"With all of the injuries, he got a chance to come up to the big leagues quicker than any of us anticipated," Miami manager Mike Redmond said. "It's one thing to get the opportunity to come to the big leagues when you're young. It's another to take advantage of that. He's done that."

A year ago, Dietrich was progressing from Class A Charlotte to Double-A Montgomery in Tampa Bay's system.

Naturally, the left-handed hitting infielder felt his future was with the Rays.

This week, Dietrich is getting his first chance to face the Rays in Interleague Play.

"Tampa was obviously my first organization," Dietrich said. "The goal there was to help out the big league team. Now, I'm blessed to have the opportunity to be helping out the Marlins. It is a little weird being in this side of the clubhouse."

Although Dietrich didn't attend big league camp with Tampa Bay, he is familiar with a number of players in the organization.

"It's nice to see those guys," he said. "But once you are on the field it is business as usual.

"The Rays do a great job in raising their players. They really prepare you to be a successful big leaguer. I definitely got better in their organization. I appreciate everything they did for me, giving me that first opportunity. But I'm happy to be here, and be with the Marlins. I couldn't be in a better spot."

Brantly getting valuable experience behind dish

ST. PETERSBURG -- Learning from mistakes is all part of the process for Marlins catcher Rob Brantly.

The 23-year-old was involved in a couple of rough plays in Monday's 10-6 loss to the Rays at Tropicana Field.

In the second inning, on Ben Zobrist's bunt with runners on first and third, he threw to second in hopes of turning a double play. Instead, the throw pulled shortstop Adeiny Hechavarria off the bag. Brantly was charged with an error on the throw, and with two outs, Kelly Johnson belted a three-run homer.

Tampa Bay scored six runs in the second inning off starter Jose Fernandez, but only three were earned.

Another play Brantly was upset at himself came in the sixth inning when Dan Jennings was intentionally walking Evan Longoria. Johnson was on second base, and he noticed Jennings wasn't paying attention to him. So he stole third base during an intentional walk.

Brantly saw Johnson inching closer to third. While Jennings should have checked the runner better, Brantly said he should have called time to remind the pitcher to freeze the runner.

"It just gives you new things to anticipate that you should have anticipated before," Brantly said. "You learn from it. You don't forget things like that. That's embarrassing. For me, as a catcher, who gets to see the field, I don't have my back turned to runners. It's embarrassing for me to let that happen."

Regarding the bunt play, Brantly said: "It's a judgment call. I think the obvious judgment call is when you look at a guy at third base, you're not going to have time to turn the double play. I should have taken the sure out at first base after looking the guy back at third. But I made a decision, and I went for it. You've got to learn from your experiences."

Like many of the Marlins, Brantly is gaining valuable experience at an early age. He's 23, and he has 59 big league starts under his belt, including 31 this season.

"New situations happen all the time," Brantly said.

Eovaldi could join Marlins by mid-June

ST. PETERSBURG -- All signs are encouraging for Nathan Eovaldi to join the Marlins' rotation by mid-June.

The 23-year-old is on the 60-day disabled list with right shoulder inflammation, and the earliest series he could return is June 10-12 at home against the Brewers.

Eovaldi, placed on the DL the day before the season started, is scheduled to make two more rehab starts, beginning Thursday for Class A Jupiter.

Marlins manager Mike Redmond said on Tuesday that Eovaldi likely will throw Thursday for Jupiter and then complete his rehab stint at Double-A Jacksonville.

Eovaldi made his first rehab start last Saturday for Jupiter, giving up one run on four hits with five strikeouts in five innings.

"He just needs to get his pitches in," Redmond said. "Whether that is two more starts in Jupiter, or we move him up to Jacksonville. That's probably what we'll do is one more in Jupiter, and one more in Jacksonville, and then decide.

"All the reports are good. He says he feels great. Right now, he's just building up and it looks good for him."

Worth noting

• Logan Morrison has joined Double-A Jacksonville for the second leg of his rehab assignment. The first baseman, on the 60-day disabled list since the season started, began his rehab stint at Class A Jupiter. The 25-year-old is recovering from right knee surgery.

• Donovan Solano (left intercostal strain) is doing baseball activities in Jupiter, and he could begin his rehab assignment within a few days.

• Joe Mahoney (right hamstring strain) is close to resuming his rehab assignment with the Hammerheads.

• Giancarlo Stanton (strained right hamstring) is expected to be out at least a few more weeks.
