After two Minor League starts, Dallas Keuchel is expected to make his debut with the Atlanta Braves on Friday versus the Washington Nationals.
Over 14 innings, the left-hander allowed three runs and struck out 13 batters.
Keuchel signed a one-year, $13 million deal with the Braves earlier this month.
The Braves have a three-game lead over the Philadelphia Phillies in the National League East.
