Dietrich reconnects with Georgia Tech ties

ATLANTA -- It's been a homecoming of sorts this week for Marlins rookie second baseman Derek Dietrich, who attended Georgia Tech.

Dietrich played his college ball in downtown Atlanta, about 10 minutes away from Turner Field. While in school, he occasionally attended Braves games, where he watched players like Brian McCann.

During an at-bat on Tuesday night, Dietrich talked briefly with McCann.

"I would watch him when I was at school," Dietrich said. "He was catching when I stepped in the box. He even said, 'I just saw that you went to Georgia Tech.' He was like, 'What years?' and stuff."

Several friends who still live in the area visited Dietrich at the ballpark on Tuesday night.

"It's fun being back, that's for sure," Dietrich said. "It's even sweeter to be here as a professional, in the big leagues, for the Marlins. I really enjoyed playing here at Georgia Tech."

Dietrich even caught up with Braves right fielder Jason Heyward. In high school, the two played together during the Aflac Games and East Cobb tournaments in the Atlanta area.

The Rays drafted Dietrich in 2010. While in Tampa Bay's organization, he got to know B.J. Upton, who is now with Atlanta.

"There are some friends who still work here in Atlanta, or are living here," Dietrich said. "A couple of my friends came to the game last night. It's nice to have family and friends here."

LoMo gets day off after collision at first base

ATLANTA -- The collision looked worse than it was, which is fortunate for Logan Morrison and Kris Medlen.

Morrison and Medlen hooked up in a nasty spill at first base in the third inning on Tuesday night at Turner Field.

Medlen, the Braves pitcher, dropped down a bunt that was fielded by third baseman Placido Polanco. The throw to Morrison drew the first baseman into Medlen.

Morrison went airborne, was spun around and crashed to the ground. Initially he was in intense pain, and the Marlins' training staff rushed to the field.

"I felt like a helicopter," Morrison joked on Wednesday.

Morrison shook it off and played the rest of Tuesday's game. But his hip was a bit sore on Wednesday, and he was given the day off. Conditions in Atlanta are wet, and the Braves started lefty Mike Minor, which also led to the decision to sit the left-handed-hitting Morrison a day.

"I landed on my hip, and I had pain on my hip and my back," Morrison said. "I'm OK now. I'll be fine."

Medlen continued pitching, and he did so with a scrape on his forearm. He told Morrison: "Dude, I haven't had a strawberry since college."

Upon contact, it looked as if both players could have been seriously hurt.

"It did hurt. It was scary too," Morrison said. "I felt like a pop in my back. Obviously you have a shooting pain, but it was fine."

Marlins manager Mike Redmond didn't want to push Morrison back into action on Wednesday.

"He landed pretty hard," Redmond said. "His back has been bothering him a little bit the last week to 10 days. He came in today and he was a little stiff. Get him out of there and give him a day against the lefty and hope he feels better tomorrow."

Marlins opt to designate Olivo for assignment

ATLANTA -- The Marlins on Wednesday removed Miguel Olivo from the restricted list and designated the veteran catcher for assignment.

Miami placed Olivo on the restricted list on June 15 after the backup catcher walked out on the team prior to a game against the Cardinals the previous day. On the restricted list, the Marlins were not paying Olivo.

Olivo was unhappy with a lack of playing time, and in a meeting with the club, expressed that he wanted to be released. When the team didn't agree, the backup catcher got dressed and departed the clubhouse.

Being designated, the Marlins have a 10-day period to either trade or release Olivo. Or Olivo could accept the assignment, and agree to go to Triple-A New Orleans.

The Marlins signed Olivo for $800,000 at the end of Spring Training. He was brought in to back up Rob Brantly because Jeff Mathis opened the season on the disabled list with a broken right collarbone.

In 33 games with Miami, Olivo batted .203 with four home runs and nine RBIs. His playing time diminished when Mathis was reinstated from the DL on May 14.

Worth noting

• Reliever Ryan Webb is fine after being struck on the right foot on a comeback infield single on Tuesday night. Webb was clipped on a shot off the bat of Jordan Schafer. An X-ray was taken, and it came back negative.

• The Marlins announced their top international signings on Wednesday: catchers Luis Tejada (Dominican Republic) and Pablo Garcia (D.R.); outfielders Johnny Santos (Panama) and Josue Guzman (D.R.); shortstops Ermel Pena (D.R.), Yefry Reyes (D.R.) and Galvi Lara (D.R.); and left-hander Roberto Tejada (D.R.).
