MILWAUKEE -- Corey Patterson's parents called him after his first career public temper tantrum, but didn't punish him.
"They're actually proud of me," Patterson said Wednesday.
The Chicago Cubs center fielder was ejected from Tuesday's game in the sixth inning for arguing a call at first base with umpire Bob Davidson. It was Patterson's first career ejection, and surprised his teammates.
"[Cubs coach Gary Matthews] talked to him and he just said on the way back, he realized how mad he was," Cubs manager Dusty Baker said. "A lot of quiet guys, when they snap, they snap pretty good. I was always told, beware of the quiet ones."
Patterson learned from the experience.
"I didn't get anything resolved," he said of his outburst. "But if you don't show certain things, then people think they can walk over you. Sometimes you've got to let people know."
Patterson didn't say anything to Davidson, but did throw his helmet in the direction of the umpire and that could cost him. No word yet from MLB vice president of on-field operations Bob Watson on a possible penalty.
Baker would like to see more emotion out of the 25-year-old outfielder but in a more controlled way, if that's possible.
"Not necessarily on the field but you'd like to see some fire," Baker said. "You know the fire is there. He's kind of a laid-back young man. That shocked everybody in the house."
Step by step: Joe Borowski struck out two over one inning for Triple-A Iowa on Tuesday in his first rehab outing, and will throw again on Thursday. Borowski is on a fast-pace rehab after suffering a non-displaced fracture in his right wrist on March 21.
"I'm very pleased and I'm sure he is, too," Baker said of Borowski.
The next test will be to throw back-to-back days. No timetable has been set for that.
Cubs athletic trainer Mark O'Neal said Todd Walker also is progressing well from his sprained left knee. The second baseman was in Chicago doing some underwater hydrotherapy treatment. On Friday, Walker will be on the field and, if all goes well, O'Neal said they planned on increasing his activity. Walker was on the field in Houston over the weekend.
Decision time: Chad Fox was examined by orthopedic specialist Dr. James Andrews on Wednesday in Birmingham, Ala., and the Cubs reliever had yet to announce what his next step would be.
"I think he had a tough time trying to distinguish what it was that he felt out there that day," O'Neal said of Fox, who had to leave the April 25 game after feeling a "pop" in his elbow throwing a pitch.
"The biggest thing he's trying to deal with is an ulnar nerve issue," O'Neal said. "He still has a lot of pain and numbness in his fingers and that's got to quiet down before we can do anything.
"You're probably looking at at least a good three to four weeks for that to quiet down and see where we are then," O'Neal said. "Then he's going to have to make a decision on whether they want to go in and explore it, not pitch again, or try to rehab it and see if he can pitch. I think Chad's trying to decide that right now."
The ulnar nerve pain sidelined the right-hander last season. Fox is experiencing the same problems, and his right hand is numb and weak. An MRI on his elbow was inconclusive.
"The underlying question is what's causing this," O'Neal said.
Aramis Ramirez / 3B
Weight: 215 lbs
Bats: R / Throws: R
Realignment, Part I: Aramis Ramirez batted third on Wednesday, in front of Derrek Lee, in hopes of getting a jumpstart.
"When you're not going good, they make Gold Glovers out of everybody," Baker said. "I know he's going to hit."
There are no lingering problems with Ramirez's groin.
"His stroke is off," Baker said. "When your stroke is off, you're late on fastballs and early on breaking balls, and that's where he is right now."
Realignment, Part II: Mark Prior will start on Friday and Glendon Rusch on Saturday for the Cubs when they open a three-game series against Philadelphia. It will be Rusch's first start of the season as he steps in for Kerry Wood, out with a muscle strain in his right shoulder. Ryan Dempster will stay in the rotation -- for now.
"Everything's off for now," Baker said about moving Dempster to the bullpen. "[Putting Dempster in the pen] is something we might want to think about. It depends on how things go. I don't want him teeter-tottering on both -- that's not right. Right now, he's still a starter."
And LaTroy Hawkins is still the closer, although Baker said that is "situational."
"It's more LaTroy because of the young guys I've got out there -- I've got a very young bullpen," he said.
Left out: Jason Dubois muffed a ball in left field on Tuesday, and dropped a fly ball by Ken Griffey Jr. in Chicago, which is part of the reason the rookie isn't playing every day.
"That's one of the factors of playing [Todd] Hollandsworth when everybody asked, 'Why isn't Dubois playing every day?'" Baker said. "He's made a lot of improvement from two years ago to last year to this year. Will he ever [win] a Gold Glove? Probably not. But he's made some pretty good plays that have surprised us."
The problem on Tuesday at Miller Park was that Dubois didn't use his legs well, and the ball skipped past him.
"When you're not sure of yourself, he charged and stopped and charged again. The rule is if you start, you come all the way," Baker said. "If you don't get there in time, you figure out the next best way to keep that ball in front of you."
Dubois works hard during batting practice to catch as many fly balls as he can and get a better read.
"He feels terrible [when he makes a mistake]," Baker said. "I had to tell him to pick his head up when he missed that fly ball in Chicago. He was feeling bad the next day."
