"I knew something was wrong because of the way I was swinging. It felt like my right arm was giving up on me. I couldn't get the full extension. I'm just happy that we got it right. I'm going to rehab and we'll go from there until next year."
Guillen said, because of his work ethic, he will be swinging the bat in three months and be ready for Spring Training.
"I'll be 100 percent, no doubt in my mind. I'll be ready by Spring Training. I'm not going to rush anything. I know how fast I heal. The doctors are surprised that I have my arm fully extended," Guillen said.
Guillen is a free agent after the season and said he would re-sign with the Nationals, even if it was an incentive-laden deal. He also wants Frank Robinson to continue to be the manager.
"This is where I want to come back, especially if [manager] Frank [Robinson] stays here for one more year. [The organization] knows me. I already talked to [general manager] Jim [Bowden]. There has been some good conversation. I'm confident that I'm going to come back here," Guillen said.
Robinson said he was not surprised that Guillen tried to play through the injury.
"It was tough to see him struggle, period," Robinson said. "But knowing him, you know he was going to go out there. He was going to go out there if he had to kick the ball into the infield. You admire him for that. He's what you call a gamer -- he wants to play and he wants to win. There's nothing wrong with that."
Talking heads: MLB.com's Mark Sheldon reported on Wednesday that Reds general manager Wayne Krivsky and Bowden talked on Tuesday, and apparently it yielded little resolution.
Both clubs remained at odds over the medical history of right-hander Gary Majewski, who Washington sent to Cincinnati on July 13 in an eight-player trade that sent Austin Kearns and Felipe Lopez to the Nationals.
"I said some things I wanted him to hear," Krivsky told the Cincinnati press. "Then he countered and I countered and so forth and so on. He feels like he complied and I think we feel there [are] some gaps."
Bowden declined to discuss what was said between him and Krivsky.
"I am not going to comment on my private conversation with Wayne," Bowden said.
Movers and shakers: The Nationals named Lenny Harris as their Minor League roving infield instructor on Wednesday. Harris last played the game of baseball in 2005, hitting .314 in 83 games for the Marlins.
One of the best pinch-hitters of all time, Harris played for general manager Jim Bowden when both were with the Reds from 1994-98.
Right-hander Zachery Zinicola, drafted in the sixth round of the 2006 First Year Player Draft, was promoted to Double-A Harrisburg on Wednesday. He started with Class A Vermont, where he did not allow a run in nine innings and collected four saves. Zinicola was then sent to Class A Potomac where he pitched in nine games and was 3-0 with a 1.89 ERA and three saves.
Injury report: Second baseman Jose Vidro, on the disabled list because of a left hamstring strain, is expected to rehab in Class A Potomac on Friday. Vidro said that once he is healthy, he expects to be traded and possibly make a position switch.
Before the trade deadline, the Giants had interest in Vidro, and, reportedly, were prepared to have him play first base.
"It's not a secret. [The Lerner Group] basically said they had a plan to develop the Minor League system. They traded a couple of guys already," Vidro said.
Left-hander Mike O'Connor, on the disabled list with a mild left elbow flexor strain, is expected to play catch for the first time on Saturday. There is no timetable when he will have a bullpen session.
Left-hander Micah Bowie left Wednesday's game because of a mild latissimus dorsi strain -- the shoulder blade region. He is listed as day-to-day. With Bowie out, the Nationals don't have a left-hander out of the bullpen.
Bowie entered the game in the seventh inning, pitched one-third of an inning and got out of a bases-loaded jam against the Marlins.
"I felt a little something and I told [pitching coach Randy St. Claire], 'It's a little sore,'" Bowie said. "He said to shut it down and get it checked out."
Bowie has been a pleasant surprise for the Nationals, giving up just three runs in 19 2/3 innings.
Stat of the day: Entering Wednesday's action, the Nationals' bullpen is 4-2 with a 3.14 ERA and seven saves in their last 20 games.
Did you know? Twenty-nine of Alfonso Soriano's 35 home runs have come while batting in the leadoff position.
Coming up: The Nationals play the third game of a three-game series against the Marlins on Thursday night at 7:05 p.m. ET. Right-hander Pedro Astacio will take the mound for Washington, while right-hander Anibal Sanchez goes to the hill for Florida.
