WASHINGTON -- The Padres placed second baseman Orlando Hudson on the 15-day disabled list on Friday for the second time in May, this time with a Grade 2 groin strain.

The move is retroactive to May 26.

Hudson removed himself from Wednesday's game against the Cardinals after he reached first base on an infield single. An MRI late Wednesday showed a Grade 2 strain, which is considered a moderate strain.

"This wasn't going to be a quick-healing injury," Padres manager Bud Black said before Friday's game against the Nationals.

Hudson missed 13 games earlier this month with a strained right hamstring, an injury he suffered running the bases.

Hudson spent most of Friday afternoon getting treatment on his groin inside the visiting clubhouse at Nationals Park.

"It's baseball, it happens," Hudson said of the two injuries he's had this month. "It's just another small stepping stone. You've got to just take your time with injuries and do all that's needed to get better."

Hudson was hitting .245 when he suffered the hamstring strain in a game May 3 against the Pirates. He returned from the disabled list May 19, but was just 2-for-21 in his first seven games back, dropping his average to .217.

"Orlando is down, he wants to play," Black said. "When he's not playing, he's bummed. But he'll do everything he can on the disabled list to get himself healthy."

In Hudson's absence, the Padres will use Alberto Gonzalez and Eric Patterson at second base. Black did indicate that Logan Forsythe, who joined the team on Friday from Triple-A Tucson, will see time there as well.

Forsythe was 0-for-7 in six games while Hudson was first on the disabled list. He started one game in that stretch, May 8 against the D-backs.

In 28 games with Tucson, Forsythe was hitting .270 with five home runs and 24 RBIs in 111 at-bats.

Trio of Padres visits Walter Reed Army hospital

WASHINGTON -- Pitchers Tim Stauffer, Aaron Harang and Luke Gregerson spent part of Friday visiting soldiers and their families at the Walter Reed Army Medical Center in Washington, D.C.

This was the second trip in as many years for Harang, who visited the medical center a year ago while he was still pitching for the Reds.

"To be able to talk to the soldiers ... we can't experience what they've endured," Harang said. "It shows we appreciate what they do and care about what they do. Hopefully ... we brightened their day."

Stauffer, Harang and Gregerson spent an hour or so at the medical center and talked with injured soldiers and the families who were visiting them. Harang marveled afterwards at the bright disposition of the soldiers.

"It was interesting to see how positive they were," Harang said. "They're optimistic."

Bartlett starting to heat up at the plate

WASHINGTON -- It's been some month for Padres shortstop Jason Bartlett, who has hit safely in 14 of his last 17 games, raising his average from .217 to .258 in that stretch.

Bartlett, who earlier this month had an RBI in nine consecutive games, entered Friday's game with the second-most RBIs (16) in the National League by a player without a home run, trailing Colorado's Dexter Fowler, who has 18 RBIs without the benefit of a homer.

That all changed in the top of the ninth inning when Bartlett hit his first home run of the season, a stretch of 247 at-bats dating back to last season when he was with the Rays.

Power, obviously, isn't Bartlett's strong suit, though spraying the ball around the field has been during this stretch.

"On balls down the middle and middle-in, he turns on it ... the ball comes off the bat hot," Padres manager Bud Black said. "He also has the ability to go line to line. That's what makes him such a good hitter."

Worth noting

San Diego manager Bud Black indicated that rookie outfielder Blake Tekotte, who has yet to appear in a game since he was recalled from Double-A San Antonio on Monday, could make a start Saturday, as the Nationals will throw a right-handed pitcher (Jordan Zimmermann). Tekotte is a left-handed hitter. ... Catcher Nick Hundley, on the 15-day disabled list since May 6 (retroactive to May 5) with a strained oblique, is closing in on being able to do full baseball activities, which could include testing his oblique during live batting practice. Hundley is set to hit balls off a tee and in soft-toss drills this weekend.
