"I re-aggravated it with the line drive. I was trying to get out of the way of it," Bowie said. "I tried to see if I was good enough to start [Tuesday], and it wasn't going to happen."
For Redding, he will make his first Major League appearance since 2005, when he was with the Yankees. Redding has spent this season with Triple-A Columbus, where he was 9-5 with a 5.32 ERA.
General manager Jim Bowden indicated that Redding was called up because it was his regular turn to throw. Bowden gave no indication if Redding will be with the team after Tuesday. If he is, Redding will pitch against the Brewers on Saturday.
Redding will become the 10th starting pitcher for the Nationals this season, tying the Phillies for the National League lead.
"He has had some good outings as of late," manager Manny Acta said. "He has gotten better as the season has gone on."
During Spring Training, it was assumed that Redding was one of the leading candidates to be in the Nationals' rotation because he played for Acta when both were in the Astros' Minor League system early in the decade, but Redding was hit hard and was sent down toward the end of camp.
The Big Nasty: Right-hander John Patterson said he is not worried about his baseball career even though he will miss most of the season with nerve problems in his right elbow and biceps.
Patterson, 29, is avoiding surgery, and he plans to go to Toronto and get treatments similar to what Athletics closer Huston Street went through recently. Patterson will deal with chiropractors, be in a hyperbaric chamber and have homeopathic injections, lasers and frequency-specific microcurrents. These types of treatments are not approved in the United States. Patterson will be working with Dr. Anthony Galea.
"I'm holding out hope that he can fix it without surgery," Patterson said.
Patterson will begin the treatments, expected to last 18 days, on July 10. Patterson is hoping to play in a Major League game sometime in September.
"It is a setback? Yeah, because I haven't pitched much this year and I had surgery last year," Patterson said. "I don't feel bad. It's not like my body is physically broken down or I'm mentally broken down. Fix the problem, and I'll be back on the field doing what I do. It's not like I'm 35 or 36 years old. I have a lot of time left in my career."
Injury report: Reliever Jesus Colome left the hospital recently after being treated for a soft tissue infection in the right buttocks. Bowden said there is no timetable for his return.
"I never had a player who had this problem before," Bowden said. "It was a large buttocks problem. The infection is serious. He was kept in the hospital for a number of days with IV. It was a serious situation."
Shawn Hill (left shoulder and right elbow) played catch again on Monday and didn't feel any pain. He had two sets of 25 throws. The first session was at 60 feet, and the other was at 75 feet.
Hill will play catch on Wednesday. After that, he hopes to be playing catch on a daily basis and then have a bullpen session sometime after the All-Star break.
Stat of the day: The Nationals are 13-12 in one-run games this season.
Did you know? Entering Monday's action, the Nationals have won seven series and lost 17 this season.
Coming up: The Nationals will play the second game of a four-game series against the Cubs on Tuesday night. Redding will face Chicago right-hander Carlos Zambrano.
