"I learned quite a bit," Fields said. "I definitely had some ups and downs this year, but I'm trying to pull from it all and learn about what it takes to be here. I've had a great time with my teammates. This team has gotten to be pretty close throughout the course of the year, and we have a lot of new faces."
Fields is one of seven Astros pitchers to make their Major League debut this year, including six in the bullpen alone. They're all trying to compete for spots next year and open some eyes, which could lead to some players trying to do too much.
"I feel like sometimes I tend to try to push it too hard," Fields said. "I want to continue to work hard like I've been doing, but make sure I'm feeling good and ready for next year. The biggest thing for me is just stay focused and stay to the grind."
Fields understands the Astros are rebuilding. And while watching the losses pile up has been tough, he can't help but be enthused for the future.
"We all know it's going to be a process," he said. "We weren't expected to win and the hopes for the team, as far as the fans, wasn't very high this year, and it was kind of a year to give some guys an opportunity to help this club out in the future. I think that some of the guys realized that, and you have to keep a big-picture mindset and say, 'You know what, everybody's young and we're going to continue to get better and hopefully make a push in the year to come.'"
