As the Braves await word on whether Brandon Beachy will join Kris Medlen in requiring a second Tommy John surgery, the team is not considering adding another starting pitcher, general manager Frank Wren said.

Wren, in a telephone interview Saturday morning, told Fox Sports that the signing of free-agent right-hander Ervin Santana and expected returns of lefty Mike Minor and righty Gavin Floyd early in the season should give the Braves sufficient depth.

"Right now, we plan on going with what we have," Wren said. "We like what we have."

Santana, who signed a one-year, $14.1 million contract with the Braves on Wednesday, could join the rotation in mid-April, right around the time the team needs a fifth starter or close to it, Wren said.

Minor, who underwent a urinary tract procedure Dec. 31, experienced shoulder soreness early in camp and is about a month behind schedule, making him likely to join the rotation in mid- to late April.

Floyd, recovering from Tommy John surgery, has been "extremely impressive," Wren said, and could return in early to mid-May.

To start the season, the Braves likely will go with an unlikely collection in their rotation -- right-handers Julio Teheran, Freddy Garcia and David Hale along with left-hander Alex Wood.

"When we get Santana in there, it will move everyone down a notch," Wren said. "Within a couple of weeks, we'll have Minor and Floyd. Then, all of a sudden, we'll have our depth again."

Scouts, meanwhile, have expressed recent concern about the defense of Evan Gattis, who is replacing Brian McCann as the Braves' primary catcher.

Wren, however, said that Gattis had only one bad game behind the plate, and referred to it as "an aberration."

"He's blocking the ball great. He's throwing well. He calls a good game," Wren said. "Receiving is always going to be the thing he has to work on."

Wren said the plan is for Gattis to start about 100 games at catcher, with Gerald Laird and Ryan Doumit filling in the rest.
