Yasiel Puig, the top prospect of the Los Angeles Dodgers, was arrested early Sunday in Chattanooga, Tenn., and charged with speeding, reckless driving and driving without proof of insurance.

Puig is on the seven-day disabled list at Double-A Chattanooga with a sprained left thumb.

"We're aware of the situation and we take it very seriously," a Dodgers spokesman said. "We'll be handling discipline internally."

The Dodgers signed Puig, 22, to a seven-year, $42 million contract last June.

With a star-laden starting lineup, the Los Angeles Dodgers have looked to add versatile players to their bench.

Ned Colletti has players like Mark Ellis, Nick Punto and Skip Schumaker on his bench.

Ellis is nursing a thigh injury that will keep him out a few weeks, but Punto and Schumaker can fill in across the diamond.

"I like our guys. We're pretty flexible over there," Don Mattingly said.

Los Angeles Dodgers shortstop Hanley Ramirez will begin a minor league rehabilitation assignment Saturday and could rejoin the team as early as Tuesday.

When Ramirez had surgery March 22 to repair a torn tendon in his right thumb, doctors predicted he would be out roughly eight weeks.

He has said that he plans to come back much earlier.

Ramirez's return has been helped by a flexible splint that allows him to hit and make throws without further injuring his thumb.

Matt Kemp hasn't been driving the ball this season, which may indicate that he's still building strength in his shoulder.

The outfielder had offseason labrum surgery on his left shoulder.

Kemp hasn't done much on inside pitches -- through Wednesday, he was 6-for-27 (.222) with one walk.

During his MVP-caliber 2011 season, he hit .402/.447/.698 with 14 home runs on inside pitches.

Dodgers manager Don Mattingly Thursday morning said he didn't have a day for the start of Hanley Ramirez's injury rehab assignment, but Ramirez tweeted a big hint an hour later. "Rancho coming soon!!!" tweeted Ramirez, an indication that he'll be headed to Class A Rancho Cucamonga, according to an MLB.com report.

The Tommy John surgery performed on Dodgers starting pitcher Chad Billingsley's right elbow Wednesday night went as expected, and he could be sidelined for a year, according to an MLB.com report.

Dr. Neal ElAttrache performed the operation after Billingsley complained of pain following his second start of the season.

Carlos Quentin, who returned to the San Diego Padres on Tuesday night, says he has spoken to Los Angeles Dodgers right-hander Zack Greinke since their brawl on April 11.

The incident left Greinke with a broken collarbone and Quentin with an eight-game suspension.

Quentin charged Greinke after he was hit by a pitch, leading to a bench-clearing brawl.

"First, I thanked (Greinke) for taking time to speak with me," Quentin said. "We were able to talk and have a good productive conversation. As far as the details of that conversation, that's personal."

Chad Billingsley will undergo Tommy John surgery on Wednesday, according to the Los Angeles Dodgers.

His recovery time is expected to be 12 months.

Billingsley has dealt with elbow issues this spring. In 12 innings this season, the right-hander had a 3.00 ERA and six strikeouts.

Carl Crawford has looked good with the Los Angeles Dodgers so far this season.

He is hitting .338/.427/.492 with one home run, two RBIs and three stolen bases.

"Crawford looks like the old Crawford," a scout said. "He's running well, hitting the ball to all fields."

The Boston Red Sox never pursued Ted Lilly when he was made available by the Los Angeles Dodgers because it would have been too difficult to add him to the 25-man roster.

Boston has been looking for a veteran starter they can keep at Triple A in reserve, but haven't found the right guy.
