No matter how much he insisted he felt fine, Nationals ace Stephen Strasburg didn’t look right to manager Davey Johnson from the time his first pitch sailed to the backstop.
As a result, there are new concerns about Strasburg’s health after he was examined by a doctor following Washington’s 3-2 loss to the Braves Monday night in Atlanta.
‘‘I think he’s got a little tightness in his forearm,’’ Johnson said. ‘‘So they’re going to put him on some medication.’’
Johnson said the hard-throwing righthander will have to show he is ready to make his next scheduled start.
‘‘It’s too early,’’ Johnson said when asked about Strasburg’s status. ‘‘I'm sure he’s going to be examined every way you can look at him.’’
Strasburg insisted he won’t miss a start.
Strasburg had lost a career-worst four straight starts before pitching six innings and getting a no-decision. He is 1-4 with a 3.13 ERA.
Strasburg appeared to struggle to get comfortable on the mound, sometimes shaking his arm after a pitch. He gave up two runs and six hits, walking four and striking out eight.
‘‘His command was way off, so I knew something was off,’’ Johnson said.
Strasburg insisted he ‘‘felt good’’ physically but struggled with his control.
Atlanta beat the Nationals for the eighth straight time dating to last season. The Braves ended a four-game losing streak overall after Andrelton Simmons hit a tiebreaking sacrifice fly in the seventh inning.
