SAN DIEGO -- Former Padres closer Trevor Hoffman and former teammate Aki Otsuka will sign autographs prior to Friday's game at PETCO Park, with the proceeds going to UNICEF to raise funds for the children of Japan affected by the tsunami in March.

"I saw Aki at a Little League facility in Lakeside [outside San Diego] and we got to talk, and he said he had a house about a mile from where the tsunami hit [near Sendai]," Hoffman said of Otsuka, who also has a home in the San Diego area. "I thought he and I should get together and bring attention to [tsunami relief]. He was on board with it."

The signing will take place at Park in the Park, starting at 5:30 p.m. on Friday before the Padres take on the Mariners in the first game of Interleague Play for both clubs.

Vouchers for Friday's signing will be sold for $50 each, and will include a color photo of Hoffman and Otsuka and one autograph each from them. Only 500 vouchers will be sold.

Fans are encouraged to purchase vouchers at the Gaslamp and Home Plate gates before and during Thursday's game. Walk-up purchases on Friday will only be accommodated if the event is not already sold out.

Fans unable to attend will be able to purchase a pre-signed photograph of Hoffman and Otsuka from $40 at all guest services and at the Home Plate Club concierge on Friday.

Hoffman is the Major League career saves leader who retired in January after a career in which he saved 601 games. Hoffman now works in the Padres' front office as a special assistant to team president Tom Garfinkel.

Otsuka posted a 1.75 ERA in 73 games for the Padres in 2004 and finished third in the National League Rookie of the Year voting. Otsuka had a 3.59 ERA in his final season with the Padres in 2005.

Otsuka was traded to Texas before the 2006 season, as part of the trade that sent Adrian Gonzalez and Chris Young to the Padres.

The game on Friday against the Mariners also marks Japanese Community Night at PETCO Park.

Hudson returns, Scribner optioned

SAN DIEGO -- Second baseman Orlando Hudson was back in the lineup on Thursday, and fully recovered from the strained right hamstring he suffered on May 3 when rounding second base.

The Padres placed Hudson on the 15-day disabled list the following day.

With Hudson back in the lineup and hitting seventh, the Padres sent reliever Evan Scribner back to Triple-A Tucson.

Hudson missed 13 games while on the disabled list, and said on Thursday that he was eager to get back to playing, though he did enjoy his two Minor League rehabilitation games with Tucson on Sunday and Monday.

"It brings back memories, man," Hudson said. "Brings back a lot of good memories. You know, you don't forget where you come from, but you forget how it was. But times change a lot. Guys have better ballparks now, crowds are getting bigger."

In two games and four at-bats with Tucson, Hudson went 3-for-4, with two doubles and an RBI. He scored four runs and walked three times. He went 0-for-1 with two walks at Lake Elsinore, the Padres' Class A affiliate.

Hudson said he "felt great."

The 33-year-old probably didn't need the entire 15 days to return to full form, but Padres manager Bud Black said putting Hudson on the disabled list was the right move.

"You can hold an injured player back two, three, four games. But if you get past seven days, eight days and you're playing short, it's tough," Black said. "When you have to make that decision, you don't have a crystal ball to know when a player is going to be healthy. So in most cases, you do the correct thing: Place him on the DL, so you know when he comes back, he's fully recovered."

Now that Hudson is fully recovered, Black is happy to get his starter back.

"We need all our guys. But the guys we projected to get most of our at-bats, we need healthy and on the field," Black said. "That's the main thing; he's a good player, so we need him back."

As for Scribner, Black said he has encouraged the 25-year-old to continue to work on what got him to the big leagues.

Scribner was primarily a closer at Tucson. He threw 11 innings with the Padres over six appearances, and allowed three earned runs and 10 hits.

It was Scribner's first taste of the big leagues, and Black suspects he'll be back sooner, rather than later.

"I suspect that, in time, if we have to make a move, hopefully he's pitching well in Tucson, and when we ask our people ... that he's the guy they'd recommend to come back," Black said.

Hoffman to represent Padres at Draft

SAN DIEGO -- The Padres will have a familiar face and an iconic figure sitting at their Draft table during the 2011 First-Year Player Draft on June 6.

Trevor Hoffman, the former Padres closer and Major League career saves leader, will phone in each pick in the first round of the Draft to Commissioner Bud Selig, and will announce the three supplemental picks the team has between the first and second rounds.

Hoffman will be on hand for the Draft in Secaucus, N.J.

The Padres have five of the first 58 overall selections.

San Diego has the 10th overall selection, for not signing their first-round pick from a year ago, and then their allocated first-round pick -- the 25th overall selection.

The Padres then have three picks in the compensation round for losing free-agent pitcher Jon Garland (who signed with the Dodgers), catcher Yorvit Torrealba (Rangers) and pitcher Kevin Correia (Pirates).

Those picks are Nos. 48 (Garland), 54 (Torrealba) and 58 (Correia).

As for Hoffman -- who announced his retirement at PETCO Park in January, finishing his 18-year career with 601 saves -- he currently works in the Padres' front office as a special assistant.

Hoffman, who played the last two seasons with the Brewers after 16 seasons in San Diego, earned 552 of his 601 saves while with the Padres.
