Gyorko put on disabled list; Forsythe activated

SAN DIEGO -- Jedd Gyorko walked to his locker before Monday's game with his right leg heavily bandaged, and at the time, he wasn't sure if he had officially been put on the disabled list. But he knew he wasn't going to be able to play any time soon.

"You won't have to look at me hobble around the field," Gyorko said with a laugh.

The Padres did place their rookie second baseman on the 15-day disabled list with a groin strain. Gyorko injured himself running the bases in the 10th inning on Sunday in Colorado.

"We're hoping that when the 15 days is up he'll be ready. We're not sure though, but we're hoping," Padres manager Bud Black said. "Medically, we felt as this was not going to resolve itself in the next week."

This is the first time Gyorko has had to deal with this type of injury. Gyorko thought it was a cramp initially, but it kept getting worse.

The Padres are losing one of their hottest hitters. Gyorko is hitting .284 and leading all Major League rookies with 66 hits, and is tied for the team lead in home runs, with eight, and has a team-leading 25 RBIs.

"Yeah, it's tough," Gyorko said. "Obviously you want to be out there, especially when you're playing well, but its a part of it and you've just got to put the time in and make sure it's 100 percent."

The Padres activated Logan Forsythe from the 60-day disabled list, and placed him in the starting lineup on Monday, hitting seventh and playing second base. He made his impression felt quickly, hitting a solo homer in his first at-bat, a 445-foot shot to center. He also singled (but was picked off first), walked and score the eventual game-winning run in a 7-6 victory over the Braves.

He had missed the entire season thus far with right plantar fasciitis, but Black said Forsythe is running well and hasn't had any discomfort.

"It feels good to be back up here with the team," Forsythe said. "Foot's been feeling good, pretty close to a hundred percent. No setbacks."

Black commended his team's depth, as the Padres have had to deal with injuries to a lot of their hitters all season -- including center fielder Cameron Maybin, third baseman Chase Headley, first baseman Yonder Alonso and now Gyorko.

"When you look at our roster, the versatility that we have and the depth of the group that we had in Spring Training, we felt good about our situation if we had an injury or two," Black said.

Forsythe appeared in eight games during a rehab stint with Triple-A Tucson, and was 9-for-25 (.360) with two homers and eight walks. He also had some at-bats in extended spring training, but his activation likely would not have come this soon if Gyorko hadn't been injured.

"Ideally it might have been best if he stayed down for a few more [games] to get some more at-bats and really get in the flow of it," Black said.

"But, by necessity, he's here."

Street throws simulated game as rehab progresses

SAN DIEGO -- Hours before Monday's 7-6 win over Atlanta, Huston Street was all alone in right field, dressed in full uniform. He dropped his glove and started doing lunges and stretching out his legs -- more specifically his calf.

Street threw a simulated game on Monday, his first time facing hitters since he was placed on the 15-day disabled list after straining his left calf running prior to a game against the Blue Jays on May 31. The move as retroactive to May 30, and Street said at the time that he didn't think he'd need the entire time to get healthy.

"Threw the ball well, his calf seems to be fine," Padres manager Bud Black said.

Street threw all of his pitches, but the Padres closer does want to work on the consistency of his slider before he returns to the Padres.

Street is 0-3 with 11 saves in 12 opportunities, and has a 4.43 ERA. He has allowed seven home runs in 20 1/3 innings.

Street will pitch again on Wednesday for Class A Lake Elsinore before the Padres re-evaluate his status.

"He's close to being ready and feels confident arm-wise," Black said. "But we have to make sure his leg is fine."

Worth noting

• The Padres' interim closer, Luke Gregerson, was not available for Monday's game against the Braves after pitching in the past two games, and eight of the past 12 days. Dale Thayer handled the save situation, recording the final two outs after giving up Jason Heyward's second solo homer, to pick up his first save of the year and ninth of his career.

• To clear a spot on the 40-man roster, the Padres designated catcher John Baker for assignment.

• The Padres have some added some additions to the team's 2013 promotional lineup, including seven new weekend giveaways, Taco Tuesdays and KidsFest at the Park every Sunday.

The expanded promotions begin on July 9, the first Taco Tuesday, which will continue every Tuesday throughout the season. KidsFest begins July 14.
