MIAMI -- Marlins infielder Placido Polanco, on the seven-day concussion list, took ground balls Saturday and hit for the first time since being plunked on the helmet by a ball last Friday against the Giants.
"I'm feeling a lot better, actually," Polanco said. "I actually did more stuff [Friday], and I felt better. The day before was the first day when I rode the bike and I was still [waiting on improvement]."
Manager Mike Redmond and the doctors continue to monitor Polanco's status day to day, waiting until he's completely comfortable before putting him back on the field.
"We'll see how he feels as far as when he'll be eligible to come off and play," Redmond said. "Not going on [a] structured plan, just taking each step. It's all on him and how he feels.
"Tuesday's not out of the question. These next couple days [we'll] get him to do as much as he possibly can and then we'll be able to determine where he's at. I don't see him having to go and play Minor League games or anything like that."
Redmond not surprised by Fernandez's success
MIAMI -- Saturday night marked what could be Marlins right-hander Jose Fernandez's final home start of his rookie campaign.
As his innings limit approaches -- sometime in early September -- the 21-year-old's success hasn't stunned manager Mike Redmond.
"I don't know that I'm surprised," Redmond said. "You take a guy with his caliber of stuff and his mentality and his confidence and you give him an opportunity and he's taken advantage of it and run with it.
"Maybe the only surprise is the fact that you just don't see that happen very often -- kid come from A ball to [the] big leagues and have so much success, become an All-Star. Pitched as well as he has. He's been able to do it, and frankly, it's been a fun ride. We all look forward to coming to the ballpark to see him pitch. He's that good."
Fernandez, making a case to be the National League Rookie of the Year, was set to start the season in Double-A Jacksonville before injuries at the end of Spring Training sent right-handers Nathan Eovaldi and Henderson Alvarez to the disabled list.
Since June 1, Fernandez has the second-lowest ERA (1.64) behind the Dodgers' Clayton Kershaw (1.62). Among rookie pitchers with at least 15 starts, he has the lowest ERA (2.41), opponents' batting average (.189) and strikeouts (157).
In 12 starts at Marlins Park, Fernandez is 6-0 with a 1.40 ERA.
"Throughout the years, you always hear about guys and how good they are, but until you actually put your eyes on them and get to see them you have to form your own opinion," Redmond said. "I'd heard so many good things about him, but now to be able to see it with my own eyes they're all true. 'This kid is special,' and he is."
Koehler, Fernandez excited for Wrestling Night at park
MIAMI -- Hours before Saturday night's game between the Marlins and Rockies, ballpark personnel began setting up a ring on the west plaza of Marlins Park for Legends of Wrestling Night.
Starter Jose Fernandez, who enjoys watching the postgame fireworks and concerts, said he would be doing the same when the wrestling legends put on a show for the Saturday Spectacular following the game.
Right-hander Tom Koehler visited the ring, practicing moves from his childhood, such as The Rock's "People's Elbow" and Stone Cold Steve Austin's "Stone Cold Stunner."
"I ran in the ring about an hour ago and jumped around in there and it hurt a little bit and I wasn't getting hit by anything," said Koehler, who grew up a fan of Hulk Hogan and Austin. "Obviously it takes a lot of skill and practice to do what they do."
From the wrestling world, the Nasty Boys (Brian Knobbs and Jerry Sags), Goldberg and The Hart Foundation (Bret the Hitman Hart, Jim the Anvil Neidhart, Jimmy Mouth of the South Hart) were among those in attendance.
