Colletti says trade for top-tier pitcher is unlikely

SAN FRANCISCO -- Citing the constraints of limited supply and widespread demand five days before the Trade Deadline, Dodgers general manager Ned Colletti indicated on Saturday that he's not close to acquiring a significant pitcher.

"We may not do anything. We still have a club with upside to it," said Colletti. "There's still more from this club as it's constituted. But historically, we've been active in July and August, too. We'll see what we can do.

"I think we have the players here that can win."

Adding to previous speculation regarding deals for Tampa Bay's David Price and Philadelphia's Cole Hamels, the name of Boston's Jon Lester is circulating in Dodgers circles, although Colletti said he still isn't interested in trading the organization's three elite prospects -- Joc Pederson, Corey Seager and Julio Urias -- that it would take in some combination to land an elite veteran pitcher.

He likened the endless search for pitching to a traveler embarking on a trip through the desert making sure he has enough gas and water. He said he's open to obtaining a setup reliever or a starter.

"I'm not sure we can be choosy," he said.

Colletti also indicated that the club isn't convinced Pederson is ready to make his Major League debut with a key role in a pennant race.

"He's got things to work on, and he knows it," said Colletti. "I met with him one on one when he was in Arizona rehabbing [a shoulder separation] and asked where he thinks he's at. He's got a good perspective on what he needs to do to get better."

Colletti said hitting left-handed pitching and cutting down on strikeouts are two goals for Pederson.

Signs point to Puig staying in center field

SAN FRANCISCO -- One game into the Yasiel Puig center fielder experiment, and 104 games into the season, the Dodgers think they're onto something.

"Last night was a good sign in a lot of ways," said general manager Ned Colletti. "We had been talking about it for a while. We sat down with Yasiel -- Donnie [Mattingly] and myself and [coaches] Lo Bundy and Davey Lopes -- and explained the differences between the corners and the middle. We talked about his concentration. How long he'll be out there, I don't know."

With Puig in center, Matt Kemp returns to his original spot in right field and Carl Crawford is in left with Andre Ethier on the bench.

"I think it's the best combination for the guys we have now," said Mattingly. "There's a little more stability in center instead of a platoon if this works out. Andre can play center, right and left. Carl's in left and Scott [Van Slyke] can play the corners or give Adrian [Gonzalez] a day at first. It's kind of the best right now."

Colletti gave no indication that he's close to, or even interested in, trading any of his veteran outfielders, only that he has and will listen to other clubs when they call.
