Manaea will start Friday's game against Cleveland, Matt Kawahara of the San Francisco Chronicle reports.
Chris Bassitt was initially slated to pitch the series opener, with Manaea set to toe the rubber Saturday. The A's will instead go with the southpaw Friday followed by Frankie Montas on Saturday. The shuffle is possibly due to Bassitt throwing 24 pitches in Tuesday's All-Star Game, though the club has yet to officially comment on the change. Bassitt could still be in line to start Sunday's series finale.
