Moore encouraged by fast start

GM pleased with early success, but knows there's work ahead

SEATTLE -- Although the Royals were in first place when general manager Dayton Moore arrived Tuesday, he wasn't going giddy about that success.

"We're encouraged," Moore said. "I would use that word over 'happy.' Just encouraged over what we're doing."

As Moore settled in to watch the Royals joust with the Mariners on Tuesday night, his club had the best ERA in the Major Leagues (2.46) and was tied for the fewest errors (three). So the pitching and defense have held up quite nicely so far.

But the offense had produced a Major League low of 43 runs.

"Offensively, we've certainly got to improve, and we will," Moore said. "Once David [DeJesus] gets back in the flow of things. ... Mark Teahen will swing the bat better, Jose Guillen hasn't gotten going and Tony Pena will be swinging the bat better. And we'll get more production out of John Buck and Miguel Olivo.

"Right now, we're getting production out of Alex [Gordon] and Billy [Butler] and Grud [Mark Grudzielanek], of course. [Ross] Gload's been producing, but those other guys I think will be even better."

Moore noticed some issues in the weekend series in which the Minnesota Twins took two of three games.

"We had a couple situations in the last Minnesota series when we were just one big hit away from putting us in a position to win a game," he said.

Moore indicated there were no player moves afoot at the moment.

"You're always open-minded on how to improve your roster, but most clubs are in a wait-and-see mode right now and just evaluating their talent," he said. "Obviously, there was a lot of thought over the winter [about] putting your team together and now you want to see it play for a while."
