ATLANTA -- It's been exactly two weeks since Padres rookie catcher Yasmani Grandal suffered a strained right oblique muscle while taking a swing in a game in Cincinnati.

On Monday, Grandal took early batting practice and then another round with the team before the Padres faced the Braves at Turner Field in what is being viewed as a precursor to a Minor League rehabilitation assignment later this week.

"We're closing in on it," said Padres manager Bud Black.

Black said that Grandal will take batting practice again on Tuesday and throw to the bases before the game and then will likely advance to a rehab stint with Class A Lake Elsinore, as long as his oblique obliges.

"Hopefully, I'll get a couple of starts in the Minors and then be ready for the Giants series," Grandal said. "But it's still something we don't want to rush."

The Padres, who opened a four-game series on Monday, return home Friday for a three-game series at Petco Park against the Giants. By sending him to Lake Elsinore -- one hour north of San Diego -- Grandal would be close enough to join the team quicker than if he was with another affiliate.

Grandal, a switch-hitter, was hitting left-handed in a game against the Reds on July 30 when he left the game after swinging through a pitch from Reds reliever Alfredo Simon.

Grandal took batting practice in Pittsburgh last week and initially his right-handed swing felt better than his left-handed swing. But now, he said, he's fine from both sides.

"I've made a lot of progress," Grandal said.

At the time of the injury, Grandal was hitting .312 with five home runs and 15 RBIs in his first month in the big leagues.

The Padres currently have two catchers on the roster -- John Baker and Nick Hundley. Hundley got the start Monday against the Braves.

Forsythe makes first start at shortstop

ATLANTA -- Infielder Logan Forsythe still hasn't landed at his "best" position, but manager Bud Black said he's getting closer to it. Physically, that is.

Forsythe, a third baseman by trade who has almost exclusively played second base this season, made his first start of the season at shortstop on Monday against the Braves.

Forsythe, who has appeared in 40 games at second base, became the fifth different shortstop the team has used in 2012. The others who have played there include Jason Bartlett (26 starts), Everth Cabrera (64), Andy Parrino (18) and Alexi Amarista (eight).

"I think he feels good on that side of the infield," said Padres manager Bud Black.

Forsythe has appeared at shortstop once this season and two games at third base, but before Monday had yet to make a start this season at either position.

The Padres planned on looking at Forsythe at shortstop as far back as Spring Training, but he suffered a broken bone in his left foot in March and eventually had surgery. He missed the first 54 games of the season before being reinstated from the disabled list on June 3.

Black said you can expect to see three players -- Amarista, Cabrera and Forsythe -- at the position for the rest of the regular season.
