The left-hander threw 17 pitches, walking one and striking out two.
Feliciano has yet to appear in pinstripes, but could join the team for the first time since signing his contract as a September callup if his rehab continues to progress.
The 36-year-old made five rehab appearances between the GCL Yankees and Class A Advanced Tampa prior to his move to Trenton, allowing two runs on six hits in five innings while walking one and striking out six. Trenton's season ends Sept. 3.
"I think Pedro's [promotion] depends on how he's doing," said manager Joe Girardi. "If he can help us, I'm sure we'll bring Pedro Feliciano up. They may not feel he's quite right. That's a decision they'll have to make from seeing him, because we won't have a chance to see him."
