WASHINGTON -- Following Friday's 2-1 victory over the Padres, the Nationals placed left-hander Tom Gorzelanny on the 15-day disabled list, retroactive to May 24, because of left elbow inflammation.

In his last two starts, Gorzelanny pitched 10 2 /3 innings and allowed nine runs on 16 hits. It's not known if he was hurt during those starts. For the season, Gorzelanny is 2-4 with a 4.25 ERA in nine starts. Gorzelanny was acquired from the Cubs on January 19 for three Minor Leaguers.

Gorzelanny was scheduled to pitch against the Padres on Sunday, and it's not known who will replace him in the rotation. One thing is certain: the pitcher will come from Triple-A Syracuse. The Nationals are not announcing who that pitcher will be until Saturday.

Right-handers Yunesky Maya or Craig Stammen could get the call. Maya will be on five days' rest Sunday. He is 1-4 with a 3.79 ERA in nine starts for the Chiefs. Stammen is scheduled to pitch Saturday for Syracuse, but could be pushed back a day. He is 4-2 with a 3.62 ERA in eight starts.

Werth, Riggleman have productive meeting

WASHINGTON -- Two days after saying that changes needed to be made, Nationals outfielder Jayson Werth had a meeting with manager Jim Riggleman on Friday.

The skipper said Werth's comments in Milwaukee were not directed at him. Many in the media assumed Werth wanted the team to change its manager.

Riggleman went so far as to say the conversation he had with Werth was one of the best he has had with a player. Riggleman compared the conversation to the one he had with catcher Ivan Rodriguez earlier this season, in which Riggleman told Rodriguez that his playing time would be reduced because of the emergence of Wilson Ramos.

After Wednesday's 5-3 loss to the Brewers, Werth, who signed a seven-year, $126 million contract with Washington during the offseason, was asked what needed to change for the Nationals to be successful, Werth said: "I have some ideas, obviously, and some thoughts that I don't really want to share with the world right now. I think it's pretty obvious what's going on around here."

After Friday's 2-1 victory over the Padres, Werth said his words were taken out of context. He said all he wanted was to see the Nationals win games.

"We need to start winning ballgames," Werth said. "We need to start hitting the ball. We need to do what we have to do to win games. That's all it was. And then what happened from the end of the game in Milwaukee until today, had nothing to do with me -- people making up stories and saying things they don't know what they are talking about. Basically what I said was, we need to start winning games."

According to Riggleman, Werth acknowledged that he was frustrated by the losing. Following Friday's win, the Nationals are in fifth place in the National League East -- 9 1/2 games behind the first-place Phillies, Werth's former team. The Nationals recently returned from a road trip in which they went 1-7.

"He used the word 'frustrated,'" Riggleman said. "He has been around a lot of winning, and we are not winning right now. I think there are other players who are frustrated, and Jayson is becoming one of the voices of the ballclub with his experience in the game. He expressed that frustration."

During the meeting, Riggleman said Werth gave him ideas on how to fix things. Riggleman declined to describe Werth's ideas.

"The losing that has taken place here in the [last] couple of years, that has to change," said Riggleman, explaining what Werth meant. "We have to change some things that we do -- how we play, whatever."

Reports good on Zimmerman's progress

WASHINGTON -- Nationals manager Jim Riggleman spoke to third baseman Ryan Zimmerman on Thursday. Zimmerman, who is on the disabled list after surgery to repair an abdominal injury, is performing baseball activities -- taking batting practice, hitting off a batting tee, taking ground balls and long tossing -- at the team's complex in Viera, Fla.

"He is feeling good about his work down there. He is feeling better, but he has a way to go yet," Riggleman said.

The Nationals are hoping that Zimmerman can play in a Major League game by mid-June. Zimmerman had problems with his groin and his abdomen during Spring Training, and he recovered from both before hurting the abdomen again in the first few games of the season, landing him on the disabled list.

Before going on the disabled list, Zimmerman was 10-for-28 [.357] with a homer and seven RBIs.
