Yankees outfielder Clint Frazier continues to progress from a concussion he sustained last week but does not know when he will return to the field.
Frazier, who suffered the injury when he made a catch in a game Feb. 24, worked on a tradmill for 20 minutes on Sunday and said he felt better compared to his last treadmill workout.
"I am in positive spirits right now. I feel a lot better," Frazier said, according to the New York Post's George A. King III.
The 23-year-old Frazier met with a doctor Sunday morning and told reporters he plans on being patient with his recovery from what he said was his first concussion.
"It's not fun all around. I never had [a concussion] before," Frazier said. "I have big hopes and dreams this year. It's hard to sit back and not watch those things come to reality right now. It's a matter of taking my time. It's a matter of taking my time.''
Frazier hit .231 with four home runs and 17 RBIs in 39 games with New York last season, and hit .256 with 12 home runs and 42 RBIs in 74 games with Triple-A Scranton/Wilkes-Barre.
