GLENDALE, Ariz. -- Ned Colletti and Don Mattingly are checking out the dozen prospects in town for the annual Winter Development Camp, but the big league club remains job No. 1.

The general manager said the Dodgers who are recovering from injuries -- including Matt Kemp, Carl Crawford and Chad Billingsley -- are on schedule to participate in Spring Training, although that comes with a disclaimer: Baseball activities just started and the injured haven't really been tested.

Kemp stopped by Camelback Ranch-Glendale on Wednesday to take some swings off the tee with hitting coach Mark McGwire.

Colletti said he's happy with the roster as it stands and gave no indication of an imminent trade or free-agent signing.

"We're fine right now if we come into camp, we're in a good spot," Colletti said.

That spot includes eight starting pitchers, with the signings of Zack Greinke and Hyun-Jin Ryu. It includes Hanley Ramirez and Luis Cruz still tentatively at shortstop and third base, respectively, even though in winter ball Ramirez hasn't played much shortstop (even though the club wanted him to) and Cruz didn't hit well (apparently feeling the effects of the flu).

Speaking of spots, Mattingly addressed the leadoff spot in the batting order one day after visiting with Crawford. Mattingly said Crawford expects to be healed from Tommy John surgery to be the starting left fielder.

As for batting leadoff, Mattingly said Crawford is willing to bat in the No. 1 spot, even though there is a generally accepted belief in the game that Crawford prefers the No. 2 hole.

"He said he didn't know where that came from," the manager said. "He said he heard that on ESPN. He said he would do whatever we want him to do. That said, he's had his most success in the two-hole."
