"I thought he threw the ball pretty good," Girardi said. "To me it's still early. This is a guy that hasn't pitched a lot lately, and it's still early, but I thought he threw the ball OK."
Prior, 30, last appeared in a big league game in 2006 with the Cubs. He threw an inning at Triple-A last year in the Rangers' chain after being signed out of independent ball and is hoping a switch to relief work can help him get back to the Majors.
"That's my first goal -- to get back to the big leagues, earn my way back," Prior said. "I don't expect to get handed anything and know that I'm not going to get handed anything."
Girardi said that Prior will be considered for a big league roster spot depending on the results this spring.
"He is competing and we're going to watch him," Girardi said. "I think the biggest thing with Mark is you just have to see how his body's holding up and physically how he feels."
