Stiff back has Detwiler's next start in question
By Bill Ladson / MLB.com
NEW YORK -- In a need of an extra pitcher, the Nationals recalled right-hander Erick Davis from Triple-A Syracuse and optioned outfielder Jeff Kobernus to Syracuse.
The move comes after it was learned that left-hander Ross Detwiler is dealing with a stiff back, which he suffered in Friday's 6-4 win over the Mets. Detwiler pitched five innings and didn't give any indication that something was wrong.
If Detwiler can't make his next start which is scheduled for Wednesday, right-hander Ross Ohlendorf will make the start, according to manager Davey Johnson. Ohlendorf also pitched in Friday's game and allowed a run in two innings against the Mets.
It marks the second time Detwiler has dealt with an injury this year. In May, Detwiler suffered a right oblique injury, which landed him on the disabled list for a few weeks.
"Hopefully, [the trainers] can do their magic in the trainer's room and he'll be able to do his [bullpen session]," Johnson said. "If he can't do his side, there is a chance he could miss a start. I will probably [use a starter] in-house, probably go with Ohlendorf. I also want to be careful on how I use Ohlendorf in the next couple of days."
As for Davis, he will make his second stint in with the club this season. In his first stint, Davis allowed three runs in 4 1/3 innings. When he was sent back to Syracuse, he made it a point to improve his breaking pitches, especially the curveball.
"I learned what works, what doesn't work," Davis said. "By no means do I feel I worked everything out, but I went to Syracuse and worked on a few things, especially consistency with my breaking ball and my off-speed pitches. I was just learning to be myself out there every time out."
Davis found out his promotion at midnight on Saturday and hopped a plane from Syracuse to meet the team in New York that morning.
Zim throws All-Star support behind teammates
NEW YORK -- If Nationals third baseman Ryan Zimmerman had a vote, teammates Jordan Zimmermann and Ian Desmond would make the National League All-Star team.
Zimmermann leads the National League in wins with 11, and he is among the league leaders in WHIP with a 0.92 mark.
"He is just consistent," Zimmerman said. "For us who have been around him awhile, he has been like that for a good two years. He just goes out and goes about his business. It has become something we've come to expect every fifth day, which is a really good thing."
As for Desmond, he leads the Nationals in game-winning hits (10) and has been the hottest hitter during the month of June, batting .308 with eight home runs and 25 RBIs entering Saturday's action against the Mets.
"Shortstop is such a valuable position. To have someone like him to play defense and offense, it's hard to find," Zimmerman said.
• Outfielder Bryce Harper is expected to play nine innings for Double-A Harrisburg on Saturday. He is expected to have the day off Sunday and rejoin the Nationals on Monday against the Brewers.
