WASHINGTON -- Ian Desmond, on the paternity leave list following the birth of his son on Tuesday, is coming back to the Nationals on Thursday.

Nationals manager Jim Riggleman said that Desmond will return to Washington for Thursday's game with the Mets. Desmond's wife, Chelsey, gave birth to Grayson Wesley Desmond in Sarasota.

"Ian will be here tomorrow," Riggleman said. "He will be in the lineup tomorrow."

Riggleman also said that he likes the paternity leave rule, which gives players three days to be with their families. He said players should be with their families, but it also lets teams bring players up to avoid being short-handed for a few days.

"In the past, guys would go home, and sometimes it might turn into 3-4 days," Riggleman said. "That player needs to be there with his wife, but the club is a man short."

Nats put Gaudin on DL, activate Rodriguez

WASHINGTON -- The Nationals on Wednesday placed pitcher Chad Gaudin on the 15-day disabled list -- retroactive to Tuesday -- and reinstated pitcher Henry Rodriguez from the DL.

Gaudin is 1-1 with a 6.45 ERA in 10 games -- all in relief -- so far this season.

"Chad has generally been a starter, so relieving may be a little bit of an adjustment for him as far as getting up quite often in the bullpen," Nationals manager Jim Riggleman said. "We just anticipate it'll just be ... some inflammation, a little soreness that we'll able to work out of there and get him back going here in a few weeks."

Rodriguez started the season on the disabled list, retroactive to March 22, with right shoulder inflammation. But he threw very well on rehab assignments with Triple-A Syracuse and Double-A Harrisburg, finishing with a 0.73 ERA in nine games. Opposing batters hit just .190 against him.

Rodriguez has a 1-0 record with a 4.26 ERA in 32 career relief appearances in the Major Leagues. He came to Washington last December in the deal that sent Josh Willingham to the A's. Riggleman said Rodriguez can take some of the pressure off Tyler Clippard and Drew Storen in the bullpen.

"[Rodriguez has] just gotten a little better each time out [on rehab]," said Riggleman. "We just feel like right now he's ready to go, and he's throwing consistent strikes, and he's got a great arm."

Hernandez said to be subject of investigation

WASHINGTON -- CSNWashington.com reported Wednesday that Nationals pitcher Livan Hernandez is "reportedly the subject of a federal investigation involving money laundering for Angel Ayala Vazquez, a convicted drug trafficker in Puerto Rico."

A Nationals spokesman said that they "are aware of, and continue to monitor, the situation as it pertains to the Angel Manuel Ayala trial."

The spokesman said Hernandez will not be making any comment.

CSN said that a report on El Vocero, a Puerto Rican news site, said that Hernandez is one of a number of celebrities being investigated and possibly in line for charges of money laundering and bank fraud.

That report also said that Hernandez testified to a grand jury on this case two years ago. In addition, the report said that Hernandez was brought up by different witnesses as someone involved in what Vazquez did.

Harper at center of brief brouhaha

WASHINGTON -- Bryce Harper found out what happens when pro pitchers get upset on Tuesday.

FOXSports.com reported that Harper homered for Hagerstown during its Class A game in Charleston, W.V., and then "exchanged words with an opposing pitcher after taking a called third strike in a later at-bat."

The words apparently kept coming, and FOXSports.com said that both dugouts eventually came "spilling onto the field."

But no punches were thrown in the incident.

Worth noting

When the Nationals hit three homers and lost Tuesday night, that was just the second time in 495 home games that Washington outhomered a team by at least three and still lost the game. The other time came on Sept. 27, 2009, against the Braves. ... Alex Cora needs just three more hits to reach the 800 mark for his career. ... Matt Stairs needs three RBIs to reach 900 for his long career. ... Danny Espinosa has 15 RBIs, which is tops among all Major League rookies. Espinosa is also tied with Baltimore's Brian Roberts for first among all second basemen.
