CHICAGO -- Dodgers catcher Dioner Navarro and reliever Hong-Chih Kuo, both on the 15-day disabled list, could return soon, Navarro as soon as Monday.

Navarro, the backup catcher who strained an oblique muscle the last week of Spring Training, is on a rehab assignment with Double-A Chattanooga, which is playing Sunday at Carolina, logistically convenient to Florida, where the Dodgers open a three-game series Monday night.

Manager Don Mattingly said that management was "still talking about it." Navarro played three innings Saturday and was scheduled for five Sunday "to make sure he's fresh if he's available," said Mattingly. "He's done everything. He seems to be ready. If he comes out OK today, tomorrow we'll make a decision."

Kuo, who went on the disabled list last week with lower back soreness and pitching wildness, pitched well in an extended Minor League game Saturday, is scheduled to start a rehab assignment with Class A Rancho Cucamonga Monday and could be activated when he is eligible to come off the disabled list Friday.

Tightness in thigh keeps Uribe out of lineup

CHICAGO -- Dodgers second baseman Juan Uribe missed his second consecutive game Sunday with tightness high in the left thigh.

Manager Don Mattingly said Uribe was available for pinch-hitting Saturday, but not running, and would try to avoid using him Sunday because he didn't want to also have to burn a pinch-runner.

"He is day to day," Mattingly said.

He said Uribe was "ginger moving" while taking grounders Saturday and would be tested again during batting practice Sunday.

"It's high in the thigh and Stan [Conte, trainer] said that's better than in the middle, where Marcus [Thames] had it," Mattingly said.

Thames hasn't started a game since April 13, partly because of the injury, partly because of the arrival of Jerry Sands to play left field.

Aaron Miles started at second base in place of Uribe, batting leadoff, with shortstop Jamey Carroll again batting eighth.

"The guy might be the best eighth hitter in baseball," Mattingly said of Carroll. "You see how many times he turns over the batting order. He gets on base, so the pitcher makes the last out. If you start an inning with the pitcher, it's like starting with one out. It's huge."

Mattingly agrees with umps on obstruction call

CHICAGO -- Upon further review, Dodgers manager Don Mattingly thinks the umpires got the obstruction call correct in Saturday's game with the Cubs.

That's not the way he felt Saturday, when second-base umpire Bill Welke called obstruction on first baseman James Loney during a third-inning rundown when Cubs baserunner Darwin Barney veered sharply out of the running lane and onto the infield grass while being chased back to first base by second baseman Aaron Miles.

The Dodgers initially believed they executed the play properly and Barney should have been called for running out of the baseline. But after viewing replays, Mattingly said that by staying directly in the baseline, Loney gave Miles no angle to make a throw that wouldn't have hit the runner.

"I understand what the umpires saw and, honestly, I think they got it right," Mattingly said. "I thought there was more space there, but James was right behind the runner and there was no place to throw it. I'll tell him he's got to get inside to give him somewhere to throw the ball."

Barney, who was trying to get back to first after being picked off, was awarded second base on the play and Loney was charged with an error.
