Roberts encouraged in cancer fight

SAN DIEGO -- Dave Roberts, the Padres' first-year special assistant who was diagnosed with Hodgkin's lymphoma in March, has completed chemotherapy.

"The PET scan showed it was clear," Roberts said of a recent test used to detect cancer in the body. "I'm very encouraged."

Roberts, a Major League outfielder for 10 seasons, told reporters on a conference call in May that he had Hodgkin's lymphoma.

Hodgkin's lymphoma is a cancer of the lymphatic system, which is part of the immune system. As it progresses, it compromises the body's ability to fight infection.

It's one of two common types of cancers of the lymphatic system. The other type, non-Hodgkin's lymphoma, is far more common.

Roberts said he had eight chemotherapy treatments over four months. The next step for him is three weeks of radiation in mid-August.

"It's going to be a different challenge," Roberts said of radiation. "I see the light at the end of the tunnel. The support I've had has been humbling. I see the end is near, that's encouraging."

Roberts has been able to move around to the Padres' Minor League affiliates during his chemotherapy, working with players on baserunning and outfield play. He also has kept tabs on the Padres, as he worked with many of these players closely in Spring Training.

"Watching these guys each night has been very therapeutic," Roberts said. "... It's made me feel very good."

MRI shows Eckstein injury only a strain

SAN DIEGO -- Padres second baseman David Eckstein said he was encouraged by the results of an MRI on his right calf on Monday, which revealed his injury is nothing more than a strain.

"[The results were] probably better than expected," Eckstein said. "They were happy with what they found."

Eckstein, on the 15-day disabled list since July 21 after sustaining the injury on the basepaths during the first inning of the Padres' game in Atlanta on July 20, said there is no specific timetable for when he will return to baseball activities but that his calf has benefited from the week off.

"It's definitely looking good in there," Eckstein said. "Hopefully it won't be too long before we can go out there and start testing it."

Eckstein also missed seven starts this month with a calf strain he said was just below his current injury, and manager Bud Black said the most important thing is not to rush Eckstein back.

"You still don't know how long it's going to be," Black said. "But the [MRI] news wasn't a downer."

Jerry Hairston made his sixth consecutive start at second base in Eckstein's absence for Tuesday's series opener against the Dodgers at PETCO Park. During that stretch, he has gone 6-for-22 with two RBIs, three runs and two walks.

Adams getting closer to rehab stint

SAN DIEGO -- Padres reliever Mike Adams, on the 15-day disabled list since July 16 (retroactive to July 12) with a strained left oblique, threw his second bullpen session on Tuesday and could be headed for a Minor League rehab assignment late this week or early next week if the injury responds positively.

Adams threw about 30 pitches during the session and said he felt much better than he did during his first bullpen session on Saturday. He was eligible to come off the DL on Tuesday, but there's still no concrete timetable for his return.

"[My oblique] was a little bit sore at first, but as it went on a little bit, it loosened up," Adams said. "Saturday, [the injury] was a little more rough with how I felt. It felt like a dull cramp in my side, and I didn't feel that today."

Padres manager Bud Black said Adams could throw one more bullpen or batting-practice session this week before making a Minor League rehab stint.

"We'll see how it is tomorrow, Wednesday and Thursday, and then there's a chance he could be pitching," Black said. "If he feels as though he's ready for a game, and he passes a few more tests, he could be throwing in a game."

GM: Nothing 'close' on trade front

SAN DIEGO -- As of mid-afternoon Tuesday, Padres general manager Jed Hoyer said that "we're not close on anything," as the non-waiver Trade Deadline of July 31 looms closer.

Hoyer, who a week ago said the asking price was still high, said, "People are starting to get serious and engaged a little more."

The Padres are looking at adding a starting pitcher, though that might be difficult to pull off before the Trade Deadline.

The Padres are primarily looking at middle infield depth, a player who could play second base, shortstop and potentially give third baseman Chase Headley a day off on occasion.

Veteran second baseman David Eckstein is on the 15-day disabled list with a right calf strain. There's no timeline for his return, though an MRI taken on Monday didn't show damage other than the strain.

The Padres have interest in Jeff Keppinger of the Astros. Keppinger has played second base and shortstop for Houston this season.

Ryan Theriot of the Cubs is another player of interest. He also has played second base and shortstop this season.

The team also has inquired about veteran infielder Miguel Tejada of the Orioles, who could play third base and shortstop.

Bench coach Simmons will manage in AFL

SAN DIEGO -- Padres bench coach Ted Simmons will manage the Peoria Saguaros of the Arizona Fall League beginning in October.

The Saguaros will include members of the Padres Minor League organization and players from the White Sox, Reds, Twins and Rays organizations as well.

Simmons is hoping to land a Major League manager job next season.

"I've done everything but manage," Simmons said recently. "This is my third year as the bench coach [second with San Diego], and after three years, either you do it [manage] or forget about it."
