Known for his steady demeanor, the 46-year-old Moyer chose an unusual way to make his statement: He sat in the stands behind the Phillies' first-base dugout at Wrigley Field and addressed the media.
"I feel a little disheartened," the 22-year veteran said. "I feel a little bit like I've been misled. I feel like I've played this game long enough that the respect factor should be there."
Moyer leads the NL East-leading Phillies in wins and losses with a 10-9 record. His 5.47 ERA is among the highest in the majors.
Moyer went 16-7 last year and helped the Phillies win the World Series, then signed a $13 million, two-year contract in the offseason. He said that Philadelphia general manager Ruben Amaro Jr. assured him he would not be sent to the bullpen.
"Ultimately, I'm a little disheartened because I know this past winter, when I was negotiating with the Phillies, this was a sore thumb, if you will, about this potentially happening," Moyer said. "You can't promise anything in this game, but I really felt that Ruben kind of parlayed to me that this type of situation would not happen."
Moyer was told on Monday he would be going to the bullpen. The recently signed Martinez, a three-time Cy Young winner, will start in his place.
"When we signed Jamie Moyer in December it was under the pretense of being a starter," Amaro said in a statement through a team spokesman. "But right now circumstances have changed and that's why we're moving him to the bullpen."
The Phillies began the series at Chicago in a 3-8 skid. Martinez said he felt badly about Moyer's situation.
"I have all the respect in the world" for him, said Martinez, who recalled spending time with Moyer at batting practice during their years in the American League. "It was always a mutual respect and admiration.
"But Jamie being older and longer in the game, I kind of admired him. I was a young buck coming up and he was a steady veteran. ... He's my friend, my teammate and my colleague. Of course I have to feel [for him]."
Moyer is 256-194 lifetime. He made his major league debut in 1986 at Wrigley Field, when he pitched the Cubs past Steve Carlton and the Phillies.
Despite his displeasure, Moyer said he would do what the Phillies asked of him.
"I do not want to be a distraction," he said. "I refuse to be a distraction. This is a job, too, that sometimes you're in situations that you like or dislike. You have to deal with it."
Phillies manager Charlie Manuel said the decision to send Moyer to the bullpen was a difficult one.
"It was tough," Manuel said. "I would say this might have been the toughest decision I've ever made because of who it is."
Manuel acknowledged he didn't know how he would use Moyer, but said he could become a situational lefty. The manager was not sure how long it would take Moyer to get loose and worried about messing up the pitcher's routine, which Manuel credited for a large part of the lefty's success.
"We'll look for places to pitch him and keep him sharp," Manuel said. "Who knows what's going to happen?"
