Having fun is one of the most important ingredients for success in baseball.

The amount of fun that players have day in and day out in the clubhouse isn't something the average fan generally gets to see, but it has an impact on the field. Stress and anxiety don't usually translate into performance.

So, you want the atmosphere to be as fun as possible before the game and after the game. That way when you're playing baseball, it's fun as well.

A loose clubhouse atmosphere allows players do their jobs with confidence and self assurance. It's difficult to play well if your mindset is that you need to fight to stay on the team. Part of my role in the clubhouse is to make sure each guy next to me is having a good time and that nobody is down.

I'm off to a good start this season, but I try to keep an upbeat attitude even when things aren't going well. As long as things are going well for the team, that is fine with me. It's a 162-game season, so we all know fortunes change quickly. If you don't have a good season, but your team makes the playoffs, the season starts over for you. You have an opportunity to do as best you can in the playoffs.

I'm never really down when I do poorly. I haven't had a year or even a long streak where I've done horribly, so I can't attest to how that would make me feel. But I'm a positive person, so I wouldn't really harp on the negative. As long as we're playing good as a team and having fun, I think I'll be able to handle it.

You can always take some positive out of a negative. I might come in and do poorly, but the positive is that my teammates can turn around and score some runs.

Right now, we're doing well, but it doesn't really matter. It's not how you start, it's how you finish. Our management has constructed a great team. They added some key hitters like Mark DeRosa and Aubrey Huff and re-signed core pitchers. I think we're going to accomplish a lot.

I had faced DeRosa before and know what a great hitter he is. He's smart about the game. I didn't know Aubrey very well, though. But what I like about the both of them in the short time we've been teammates is that they try to keep it fun in the clubhouse.

When you can have fun -- and you win -- that's the best feeling.

All-Star closer Brian Wilson hasn't allowed a run yet this season and has picked up two saves in two opportunities for the Giants. Wilson saved 38 games last year while posting a 2.74 ERA, and he had 41 saves in 2008.
