SAN DIEGO -- Padres right-hander Tim Stauffer, who has been on the disabled list since Opening Day with a strained right elbow, will throw a bullpen session on Saturday and has a simulated game scheduled for Tuesday.

These both rate as significant steps forward in Stauffer's rehabilitation from the strain that he sustained late in Spring Training.

"We'll be able to gauge where he is," Padres manager Bud Black said.

Black figures that Stauffer will throw between 40 and 50 pitches Tuesday, and if he emerges from that fine, he'll likely head out for a Minor League rehabilitation stint before he's reinstated.

"He feels pretty good," Black said of Stauffer, who was in line to be the Opening Day starter before his elbow issues led to a drop in velocity in late March.

Edinson Volquez instead was named the Opening Day starter, with Stauffer pegged as the No. 5 starter until the Padres placed him on the 15-day disabled list on April 5, retroactive to April 4.

Honored Roberts passes on Fenway festivities

SAN DIEGO -- There's no telling when Padres first-base coach Dave Roberts will get home after Friday's game against the Phillies, but when he does he's got a date scheduled -- with his DVR.

Roberts declined an invitation to Friday's ceremony in Boston to honor the 100th anniversary of Major League play at Fenway Park. Over 200 former Red Sox players attended the ceremony that was held before the Sox's game against the Yankees.

"I recorded it," Roberts said. "I can't wait to check it out."

Roberts played in 45 games with the Red Sox in 2004, though he might have stolen the most important base in the history of the franchise that postseason.

Roberts stole second base in the ninth inning of Game 4 of the American League Championship Series against the Yankees, which helped the Red Sox, down three games to none, win that night. Boston went on to defeat the Yankees in seven games before claiming the club's first World Series title since 1918.

Roberts said Friday he didn't feel right leaving the Padres, who went into their game against the Phillies with a 3-11 record.

"It was a pretty easy decision for me," Roberts said. "This situation here ... I want to be part of it. And as much as I respect the opportunity to go back, and everyone here gave me their blessing to go, my job is to be here with these guys."

Roberts got to return to Boston last season when the Padres played the Red Sox during Interleague Play. He has returned a few times since that magical run of 2004.

"I went back for the [World Series] ring ceremony in 2005, when I was playing for the Padres. I opened the season on the disabled list, so that made it easy to receive my ring," Roberts said. "It was really unbelievable."

Padres get closer look at rehabbing Forsythe

SAN DIEGO -- There was a new face in the Padres' clubhouse on Friday, though infielder Logan Forsythe wasn't added to the active roster.

Instead, Forsythe, who had surgery last month to repair a broken bone in his left foot, arrived at Petco Park to be looked at by the medical staff as well as hit on the field and go through some drills pregame Friday and Saturday.

"He's six weeks out of surgery, and we wanted to get him here to get a jump start before he goes back to Arizona to continue [rehabilitation]," Padres manager Bud Black said. "We'll try to get him up to speed on some baseball activities."

Forsythe sustained a broken bone in his left foot in early March, which ended any hope he had of making the Opening Day roster as a utility infielder. The initial prognosis was eight weeks before he could play in games again.

Forsythe said Friday that he hopes to be playing in games in two weeks. He's also very encouraged by how his rehabilitation has gone.

"It's going really well," he said. "I know what to expect and how far I can push it. Now, I'm at the point where I need to push it further."

Forsythe stood a good shot of making the 25-man roster before the injury, especially since he can play third base and second base. The team was going to look at him a lot in Spring Training at shortstop to see if he could handle the position.

Andy Parrino, who showed he could handle all three spots and also provide some pop with his bat, won the backup-infielder job over Everth Cabrera, who is now with Triple-A Tucson.
