With the news that Reynaldo Lopez was sent back to Triple-A and Joe Ross will need to make a rehab start, Lucas Giolito is the favorite to start for the Nationals on Sunday against the Padres, Mark Zuckerman of MASN Sports reports.
Giolito is coming off a great start in his Triple-A debut, allowing no runs and striking out seven in 6.2 innings. While he has yet to officially be named the starter for Sunday, there doesn't seem to be a ready alternative for the Nationals at this time.
