The domino effect of the Mets' acquisition of Jose Uribe and Kelly Johnson on Friday began to be felt Saturday night when Wilmer Flores was not in the lineup against Dodgers righthander Zach Lee. Johnson started at second base with Ruben Tejada at short and Daniel Murphy at third. Uribe did not start.

The Mets' infield configuration could be a day-to-day thing. Terry Collins indicated Tejada will get the bulk of the work at shortstop, but second baseman Flores is now his backup.

"I've got to be careful," Collins said. "And if I say Ruben is the shortstop and I play Wilmer there tomorrow, the sky is falling. So I'm not going to say that. I'm just telling you day after day, we're going to put the people out there who we think are the right guys. If somebody gets in a slump and Kelly Johnson is swinging the bat, I'm going to get him in there. If Juan Uribe, when we get him in the lineup, if he starts tearing it up, he's going to play.

"We have not scored. We have not hit. We went out and got two guys who we think have added some offense to us. I'm not going to leave them sitting on the bench. If they're going to bring more offense than what we've got, they're going to get in there somewhere."

Johnson also can play the outfield, but general manager Sandy Alderson said that won't necessarily have an effect on rookie leftfielder Michael Conforto. "The players that are producing will play," Alderson said. "To the extent that [Conforto] is making a contribution, he'll be here. To the extent he's not making a contribution, he'll be elsewhere developing."

Jon Niese, whose wife had a baby Friday, was placed on the paternity list and was replaced on the roster by righthander Logan Verrett.
