Washington Nationals righthander Stephen Strasburg is going on paternity leave as he and his wife, Rachel, await the birth of their child.
Strasburg, who is 2-0 with a 2.89 ERA and 29 strikeouts in 28 innings this season, will miss his start in the Nationals' upcoming series at Colorado.
Washington is expected to call up Jacob Turner from Triple-A Syracuse to make a start in Colorado in place of Strasburg.
He would likely return to the rotation next weekend when the New York Mets come to Washington for a three-game series.
