Nationals manager Matt Williams made the announcement Tuesday, and added Scherzer will be followed by Tanner Roark. Williams did not name a starter for Friday's road game against Atlanta.
Scherzer, who signed a seven-year, $210 million contract with Washington, is expected to throw two innings, or 45 pitches.
Williams says Scherzer's ''ready. They're all ready. But there is nothing to read into it, other than he's going to get the ball Thursday and five days later, he'll get it again.''
