It won't be Sonny Gray starting for the A's on Tuesday night after the team made a late change to their plans for Game 2 against the Rockies.
Gray was scratched Tuesday morning, according to an MLB.com report, and right-hander Chris Bassitt will take the mound in his stead.
The A's ace is dealing with sickness, according to another MLB.com report.
Gray, 25, is off to a stellar start this season and is considered a candidate to start the All-Star Game for the American League. He is 9-3 with a league-leading 2.
