Washington, D.C., was Trevor Williams'  favorite road trip when he played with the Pirates, Cubs and Mets. He is no longer a tourist in D.C. after signing a two-year deal with the Nationals this winter. Get to know the 30-year-old right-hander off the field in this Q&A.

MLB.com: Why do you wear No. 32?

Williams: The reason why I chose 32 was because I had a roommate in college named Cory Hahn who broke his neck. We have a foundation together to help people with spinal cord injuries and it's called Project 34. That was his number, and so I wore 34 with the Pirates when it became available to me in 2018. Then when I went to the Cubs, 34 wasn't really available because Jon Lester  had just come to the Nationals. I'm like, “I'm not going to take No. 34 from Jon Lester, that means too much to the Cubs.” So then when I asked my buddy Cory, I said, “What number would you have chosen?” and I gave him a list of numbers. He said he would have been No. 32 at ASU if a senior didn't have that number, so that was an easy choice. Then I went from 34 to 32, and then 32 was available with this team, so I chose 32 off that.

MLB.com: What is your warmup music and why did you pick it?

Williams: My walkout for the last ... probably since 2018 has been “Even Flow” by Pearl Jam. Pearl Jam’s one of my favorite bands. But the reason why I made the change is because Rich Hill walked out to it when he was with the Dodgers, and I heard it at Dodger Stadium, and it sounded so cool. I’m like, this is what I'm stealing from him. (Laughs) So I stole it from him, and I've been using it since.

MLB.com: Did you have any jobs growing up? If so, what were they?

Williams: My dad is an attorney, so I was a process server. I did that for my junior year and senior year of high school. Then when I was in high school, my freshman year summer, I worked at a kayak shop in San Diego. So, I did San Diego tours on a kayak, it was a lot of fun.

MLB.com: What is the most meaningful gift you gave or received?

Williams: All my Christmases and birthdays have been special. My wife and I have four kids, and it’s magical every Christmas. They’re seven and under. I had to build this dollhouse for my daughter, and I put it off for like a week. The week leading up to Christmas, I’m like, “I should probably start putting it together.” And then I just didn’t. Christmas Eve, my wife and I stayed up until like two in the morning putting together this dollhouse. It made me really appreciate what my parents did for me and my brothers. … Doing that now on the other side as a dad, it makes it more special.

MLB.com: If you could face any hitter in the history of baseball, who would you want to pitch against and why?

Williams: Anybody I could get out (laughs). Anybody that I don’t want to embarrass myself with.
