I've experienced a lot of change since getting traded to Colorado from Oakland over the winter.

For the first time, I'm playing in the National League. I'm experiencing different ballparks and different players. That's going to be a challenge, but it's also fun and exciting.

Lack of familiarity affects the way I can prepare for hitters. I don't know all of the NL hitters' strengths and weaknesses yet, so there's a bit of a learning curve.

The key, no matter what league you're in, is to go out there and make your pitches. The rest will take care of itself, but I'm feeling comfortable in the NL, and I'm excited to see what's to come.

This is also the first time I'm with a new team, so Spring Training was really helpful, because it's a place where everyone sort of comes together. You get to feel each other out, especially the new guys. I wasn't the only new guy, though.

The core group of guys here are quality, and I saw that quickly. That helped make the transition easier. It's much easier to show up to the ballpark when you like the guys you're hanging around with.

I came over here from Oakland with Greg Smith and Carlos Gonzalez, and I knew some of the guys here just from playing against them. I feel like relationships can develop pretty fast, too.

Of course, I also want to show my new teammates what I can do right away, but that's nothing new. I've always taken the approach that I need to constantly prove myself, regardless of if I have been in the league for one day or for 10 years. It's important to keep that mentality of always staying focused and always moving ahead.

That being said, you can't try too much. You don't want to go out there and put additional pressure on yourself. You need to do what you are capable of so it doesn't backfire on you.

New Rockies reliever Huston Street arrived in Colorado having amassed 94 saves and 21 wins while with Oakland from 2005-08. The right-hander from Austin, Texas, earned his first save for the Rockies on April 7 at Arizona.
