WASHINGTON -- Injured relievers Juan Gutierrez and Leo Rosales are scheduled to take steps forward in their rehabs over the next few days.

Gutierrez likely will throw a session of batting practice Saturday afternoon and could return to the active roster as soon as next Wednesday, when his disabled list stint is up.

Gutierrez has been on the DL since Aug. 3 with inflammation in his right shoulder, and the team feels it has been such a short time that he will not need a rehab assignment.

"I don't like to be on the DL," Gutierrez said. "It's so boring. It's hard to be on the DL and not do anything."

Gutierrez said he was told that the problem with his shoulder could have been caused by sleeping on it wrong. He said just before he began to feel the discomfort pitching, he woke up in the morning and could not move his arm.

To combat the problem, Gutierrez now sleeps on his left side, which took some getting used to for him.

Rosales, who has been on the disabled list since April 29 with an injured right ankle, threw a simulated game Wednesday in Milwaukee and will head out on a rehab assignment Monday.

"It's about time," said Rosales about getting out on his rehab assignment. "It's been a long time, it was worrying me a little bit. It's feels good now, my arm feels great. The training staff got me ready, they're great."

Rosales said he is scheduled to throw an inning or around 25-30 pitches on Tuesday, and he will probably spend a couple of weeks with Triple-A Reno before he's ready to return.

"Hopefully I can put up a good September and we'll take it from there," Rosales said.

D-backs talk about opening 2011 in Taiwan

WASHINGTON -- The D-backs had a pregame meeting with Gene Orza and Mike Myers of the Major League Baseball Players Association on Friday to discuss the team's possible season-opening trip to Taiwan next year.

Major League Baseball International is currently negotiating a deal with Taiwan that would have the D-backs and Giants play a pair of exhibitions as well as a pair of regular-season games overseas next March.

The Giants, who had already been briefed by the Players Association, and the D-backs would have to agree to the arrangement, and Arizona player rep Ian Kennedy said he will begin canvassing the players over the next couple of days before reporting back to the union.

"You've got some mixture," said Kennedy when asked about the initial reaction. "I haven't gotten a lot of feedback yet."

Arizona team president and CEO Derrick Hall said that if the agreement goes through, the D-backs would likely lose two regular-season games as well as the two exhibition games they play each year at Chase Field just prior to the start of the season.

The D-backs, he said, would be compensated for the missed home gates. MLB has asked the D-backs to give up two dates rather than one apiece as previously discussed, because given the Giants' higher ticket prices and larger attendance, they would require more money in compensation, Hall said.

"I didn't want to," said Hall of giving up two home dates, "but I'm willing to to make the deal work. Our [season-ticket holders] would then pay for 79 home games instead of 81. What it does for us internationally and brand exposure, we're in favor of it."

Montero welcomes special guests in DC

WASHINGTON -- Miguel Montero had a pair of special guests in the clubhouse before Friday night's game with the Nationals.

The D-backs' catcher is hosting his uncle and cousin from his native Venezuela this weekend.

Montero is very close with his uncle, Antonio, who bears a striking resemblance to Montero's late father, Angel, who passed away in March 2009.

The loss of his father was very difficult for Montero, and it is another reason why his uncle's visit was so important to Montero.

"It's great to have him here," Montero said. "Every time I look at him, he reminds me of my dad. It was hard for both of us when he died. I had him come to Washington, because it's closest for him. Well, Miami was closer, but I was on the disabled list and we were only there two days. This way I get to spend some time with him and he can see me play. It's very important to me."
