"I guess everybody else made me nervous," Sabathia said. "I kind of felt like I was pitching Friday."
Yankees manager Joe Girardi said that he would be ready to name a starter on Thursday, but he said Sabathia's bullpen session was positive.
"He aired it out pretty good," Girardi said. "We'll see how he feels tomorrow, but today was pretty good."
Sabathia said that he will continue to receive treatment from trainer Gene Monahan to make sure any lingering tendinitis can be excised from his left biceps before that start.
The $161 million ace was lifted after 1 1/3 innings in Sunday's 6-5 loss to the Marlins, as catcher Jorge Posada saw that the lefty didn't look quite right in his 28 pitches.
Sabathia said that he is battling some fatigue, but he will offer a full day's work when the Yankees make their first appearance at the new Queens ballpark.
"I'm fine," Sabathia said. "I'm ready to go, and I expect to get my full dosage of whatever it is on Friday. ... I just try to lead by example. I'm going to go out on Friday and give it everything I've got."
The lefty will obviously be hoping that the Yankees' bats have fully woken up by then. New York has had a tough time as it plays out the National League portion of its Interleague schedule.
After getting lucky in defeating the Mets twice at Yankee Stadium, the Yankees dropped two of three to the Nationals at home and another series to the Marlins in Miami before falling in the series opener, 4-0, on Tuesday in Atlanta.
"It evens out," Sabathia said. "It's a long baseball season, and there are going to be some games where you don't pitch well and they score a lot of runs. There's going to be some games where you pitch good and they don't score. We've just got to take it and keep going."
A lifetime .261 hitter, Sabathia was curious to learn who would be his scheduled mound opponent on Friday -- and he was pleased to hear it would be tall right-hander Mike Pelfrey. That is preferable to a certain left-hander on the Mets' staff, one whom the Yanks will not face this weekend.
"As long as it's not Johan [Santana]," Sabathia said, laughing.
