He had been rehabbing in Mesa, where he was diagnosed with Benign Paroxysmal Positional Vertigo ("BPPV"). After undergoing treatment there, the 24-year-old took in hitting and outfield practice before being sent back to West Tenn.
"It was like I was back at home," Greenberg said Friday. "It felt like I hadn't missed a beat in the box. My timing was off a little bit and my jumps on fly balls were off those first couple of innings. But I felt good, I felt healthy. It took a couple of innings for my legs to get back under me. It was a lot of fun and really exciting to feel healthy again."
Making the start for Huntsville in Thursday's 7-4 Jaxx win in northern Alabama was left-hander Josh Habel. Greenberg was hit by a pitch from a left-hander in Miami during his first and only big league plate appearance earlier this month.
"It was good to see the ball come at me right from the same angle," Greenberg said. "I knew I was going to take the first pitch all the way. I certainly wasn't nervous. I was more excited than anything else."
Excited didn't even begin to describe the emotion Greenberg felt on the night he and teammate Matt Murton were promoted to Chicago. Greenberg sat glued to ESPN's Baseball Tonight as they announced the Cubs' roster move which effectively sent he and Murton to the major leagues.
Greenberg hopes to return to Chicago one day this season.
"I know they called me up for a reason," he said. "They had a need and they felt I could fill that void. When they feel I'm ready, I'll be back up there."
As for now, Greenberg plans on continuing his season with the Diamond Jaxx where he is batting .273 in 75 games this season. Whether he immediately becomes a part of the club's every day lineup now that he's off the DL is something that remains to be seen.
"Right now, they want to take it step by step," Greenberg said. "The last thing you want to do is be healthy, go back out and get injured again. Whatever decisions they make, I'll take them in stride."
West Tenn opens up a three-game home series with Carolina beginning Friday. The Jaxx will honor the families of deployed Tennessee National Guard soldiers stationed in the middle east all throughout the night, and the players will wear camouflage jerseys to highlight the event.
