Dodgers add righty prospect Baez, option Fife

WASHINGTON -- The Dodgers recalled pitcher Pedro Baez from Double-A Chattanooga and optioned another pitcher, Stephen Fife, back to Triple-A Albuquerque on Monday before the start of the series with Washington.

Baez, ranked No. 10 among the team's top prospects, is a right-hander who's on the Dodgers' active roster for the first time and made his debut in the team's 4-0 loss to the Nationals. He allowed a single and a two-run homer to Danny Espinosa to open the eighth inning, but then retired the next three, including a pair of strikeouts.

Baez had a 1-0 record for Chattanooga with five saves and a 2.84 ERA. The 26-year old is a converted infielder. The question for Baez is how long he might be with the team because Clayton Kershaw is scheduled to come off the disabled list to start Tuesday's game in Washington.

Kershaw's been on the DL (teres major strain) since March 30. He earned the Opening Day win over Arizona in Australia on March 22, giving up one run on five hits in 6 2/3 innings as the Dodgers scored a 3-1 victory.

Puig out of lineup day after colliding with wall

WASHINGTON -- Dodgers right fielder Yasiel Puig was not in the starting lineup for Monday's series opener with the Nationals, and manager Don Mattingly said the situation is pretty much day to day as they're proceeding with caution.

Puig remains sore after he crashed into a fence in Miami at the end of Sunday's game. He needed some help coming off the field after colliding hard with a part of the right-field fence.

But Mattingly said there was no news about a concussion, just soreness thanks to the hard hit Puig took. Puig passed a concussion test after Sunday's game.

Mattingly is fairly optimistic Puig could return Tuesday.

"He's not feeling perfect, really sore," Mattingly said. "He hit the fence hard and he landed hard, so I think they're just making sure everything's OK."

Andre Ethier got the start in right field, batting sixth.

Mattingly said before the game that he didn't know if Puig would be available to pinch-hit or do anything later. Puig did not take batting practice before the game but had some troubles (light-headed, headaches) after riding the stationary bike, so the Dodgers decided to be cautious.

Puig was not made available to the media to talk before the game.

Ryu gets OK to begin throwing program

WASHINGTON -- Dodgers manager Don Mattingly said pitcher Hyun-Jin Ryu will begin a throwing program, possibly as early as Tuesday, after a positive visit to team surgeon Dr. Neal ElAttrache on Monday.

Ryu went on the disabled list April 28 due to left shoulder blade inflammation, something that bothered him during his last start and went back to the West Coast for Monday's visit with the doctor.

Mattingly said the doctor determined no more tests were necessary. In addition, Mattingly said it "sounds like" Ryu was pain free on Monday, so now he'll just start a throwing program.

"With everything, doc felt good, didn't need anything, just let him start working there and moving forward," Mattingly said.

Ryu said earlier that he dealt with a similar issue pitching in Korea three years ago and was doing much better in just 10 days. Plus, he said on Friday that the shoulder already felt improved from where it was before.

Worth noting

Zack Greinke pitched three innings before Monday's three-hour, 17-minute rain delay ended his night, snapping a streak of 18 straight starts in which the right-hander went five or more innings and allowed two or fewer runs. It was the longest such streak in the Major Leagues since 1914. 

• Catcher A.J. Ellis ran the bases again and feels like he'll be out playing again by the end of week somewhere. The team will decide where Ellis heads to as he's recovering from surgery on his left knee on April 8. "He's running really good. He's feeling good," Dodgers manager Don Mattingly said.

Dee Gordon's been on a roll lately. He was on a four-game hitting streak during which he's 10-for-21, giving the Dodgers more offensive help and lifting his average to .353 heading into the Washington series.

• The Dodgers have gotten at least 10 hits in five of the last eight games. In the last 12 games, they've got a .283 average with 26 doubles, four triples and 12 homers. So far this season, the Dodgers sit third in the Major Leagues with 105 extra-base hits.
