"He deserves to be the big leagues," the source said. "He would be a big help to the bullpen."
LHP John Lannan: Despite having problems in the Minor Leagues, Lannan had two quality starts against the Braves and Marlins for the big club. If the Nationals make the playoffs, people assume Lannan will replace Stephen Strasburg in the rotation once Strasburg is shutdown. That won't happen. If Strasburg is shut shown, the Nats most likely will use a four-man rotation for a short series.
C Sandy Leon: After being optioned to Syracuse on Aug. 3, Leon is 11-for-24 with two home runs (.458) entering Saturday's action.
OF Eury Perez: The Nationals may have found their center fielder and leadoff hitter of the future. Entering Saturday's action, Perez is hitting a combined .313 with 38 RBIs and 46 stolen bases for the Gulf Coast Nationals, Harrisburg and Syracuse.
RHP Chien-Ming Wang: Wang is expected to get a few more starts in the Minor Leagues before he is called up. It has been an injury-filled season for Wang. It seems doubtful that he would put on the postseason roster.
Still in conversation
3B Anthony Rendon: Washington's first-round pick in the 2011 First-Year player Draft is already with Harrisburg, and manager Davey Johnson would like to see Rendon called up to the big leagues.
"He hasn't had many at-bats," Johnson said. "I know he is a talented right-handed bat and he is on the 40-man roster. Anybody that is on the 40-man roster ... are candidates."
LHP Zack Duke: Duke has been one of Syracuse's hot pitchers of late. He leads the team in wins and has a solid 3.50 ERA.
RHP Yunesky Maya: Maya is having a good season for Syracuse, going 11-7 with a 3.42 ERA. If a pitcher like Jordan Zimmermann needs a break, Maya could get the call.
Don't look for them to be in the big leagues
IF Zack Walters: There was talk of Walters being in the big leagues because of the injury to shortstop Ian Desmond, but Desmond is back, removing the need to add an extra infielder.
1B Chris Marrero: Marrero is playing for Syracuse, but is having limited at-bats because of hamstring issues.
