The 2008 Baltimore draft pick began his career with the Frederick Keys in 2009 and posted a 4-2 record with a 2.16 ERA in 11 starts.
Matusz went four innings and gave up two hits, two walks, one earned run and struck out two batters.
On his performance
"I felt good, I felt better in the bullpen warming up before the game than on the mound. I felt like once I got on the mound I was rushing things a little bit and my rhythm was a little off, but it was nice to get four ups today. I mean that was big I needed that. I need to get up and down and be able to not think of things in between innings and just kind of gather myself. I felt like as the innings went on I was able to kind of relax and not be so mechanical and kind of be a little loose. It's a start, I needed to get my outs and get my pitches in, but there are definitely some things I need to work on. I threw some good pitches, changeups, a couple good curve balls which I threw them for strikes and worked the fastball in and out, but the command was not where I wanted it today. I am going to stick with this process and keep going. I feel healthy and that is the most important thing."
On the overall fastball command tonight
"It was a little bit off tonight. Situations throwing in the game, it has been a while since I threw in this environment. I needed that though, I needed to get my innings in while I was here. I took a lot from today, a lot of good things. I slowed myself down today with my delivery. I want to be able to watch my mechanics and make adjustments."
On how he was feeling during the game
"I felt good, I felt like I wanted to keep going to be honest with you. I felt like I was starting to get in rhythm a little bit. I felt good, feel strong. I have to continue to get work in and get those innings. I am getting there; it is getting close."
On his pitch count and what the plans are next
"I am going to have to re-evaluate that. I am going to talk with Mark Connor and Buck [Showalter] and see where we are at from today. I got my four ups just like we wanted 60 pitches four ups and that was the game plan. Looks like we are on track and I will be able to talk to those guys tonight or tomorrow and come up with a game plan. My next start will most likely be in Bowie or Norfolk and hopefully reach 75 to 80 pitches that's my guess."
On pitching in Frederick for the first time since 2009
"It was fun. It was a great experience this is a great ball park. It was great to start my career here. It's a fun place to play, fans are great, and it was great to make my first rehab start here in Frederick."
"I thought he did well for his first outing. He has overpowering stuff. He wasn't on his A game but catching a big leaguer is always fun. I had a pretty good idea where his pitches were going. It was fun catching him."
"He was trying to get his pitches down and everything. I think at the beginning of the game he was pressing a little bit. I saw the more he threw the more he got better but at the beginning he was pressing a little bit. In the third and fourth inning he got better and he located his pitches."
On if his kind of outing is to be expected in his situation
"Yea I expected that. He probably pitched two innings in rookie ball, then came in and pitched four innings and 60 pitches. It's going to take time. I think he is going to need a couple more outings before he probably pitches in the big leagues from the way I saw it. At the beginning I didn't see the hand speed that I saw before and later in the game I saw it. I think he is going to be alright. He might pitch a couple more times or one more time whatever the decision is but at this point I don't think he is completely ready to pitch in the big leagues."
