NEW YORK -- Clint Frazier said that it was "upsetting" to miss opportunities for playing time at the big league level this past season, but now that the Yankees outfielder's post-concussion symptoms appear to be under control, he is looking forward to getting on the field this coming spring.
"I'm feeling good," Frazier told the YES Network on Thursday. "It's been a long process, a process that is kind of a unique one to go through. I'm not used to feeling like I'm hungover every day. The way to beat it is to continue to do the workouts and push through the symptoms, and know that at the end of the tunnel you're going to be better."
In what he viewed as a lost season, the 24-year-old Frazier endured lingering effects from a concussion that he sustained while chasing a fly ball in the Yankees' second exhibition game of the spring. He appeared in 15 big league games between May 19 and July 15, batting .265 (9-for-34).

Though he hit .305/.388/.562 in 54 Minor League games, all but six of them at Triple-A Scranton/Wilkes-Barre, post-concussion migraines left Frazier unavailable when injuries (most notably Aaron Judge's fractured right wrist) created vacancies in the big leagues.
"That was one of the best seasons that I felt like I put together at the Triple-A level," Frazier said. "It's definitely been one of the most trying times for me in the past couple of months. It's something that I don't wish on anybody. I don't want anyone to have to go through the symptoms that I felt because it's a very uncomfortable one.
"It's a mental battle. In the end, when you can't see the ball and things are blurry and you don't feel like you're able to go out there and do what you're supposed to do, I didn't feel like it was right for me to play through that for the team. It was upsetting, because I wanted to play and I felt like I could really have helped myself and the team."
Yankees general manager Brian Cashman recently said that though Frazier remains under the care of Pittsburgh-based specialist Dr. Mickey Collins, Frazier is expected to be cleared for full on-field activity by Spring Training.
"I've been slowly hitting, throwing, working out," Frazier said. "For the most part, I'm ramping up to start doing some overhand BP, just trying to get the timing right, get the facility work out. I'm pretty much full tilt whenever I'm ready to go."
Cashman revealed at the Winter Meetings that Frazier has been recently asked about by opposing clubs. Frazier said that he has paid attention to the Hot Stove gossip, but he is more focused on players the Yankees might land, particularly after Manny Machado had a 90-minute visit to Yankee Stadium on Wednesday.
"It's hard not to see," Frazier said. "The Yankees are so publicized and that's really cool to be a part of. To see Manny Machado be at the Stadium yesterday, I hope the meeting went well, I'd love to have him. In the end, we've got other guys that can do the job if we don't."
As he did this past spring, Frazier will face an uphill battle for playing time. Brett Gardner, Aaron Hicks, Judge and Giancarlo Stanton are all guaranteed roster spots, and Jacoby Ellsbury is expected to be healthy as well, giving the Yanks six capable outfielders.
"I know there is some time to be made back up to go out there and ultimately win that job, but everyone is well deserving," Frazier said. "It's just a matter of who's probably hot at the time, what are the needs and overall how much we can help the team. I'm pretty confident in what I can do; go out there and play as hard as I can, and try to win that job and help the team."
