Estrada originally was scheduled to start Thursday, but he was moved up one day because he threw just 55 pitches in his last start vs. the Yankees. In that start, Estrada allowed eight runs on six hits and three walks over 2 2/3 innings.
Jimmy Yacabonis will make his fifth start of the season when he faces the Blue Jays. His past three starts were as the 26th man for doubleheaders, and his longest start came July 9, when he threw five innings against the Yankees.
