Estrada has tossed three consecutive quality starts, and he is coming off back-to-back wins for the first time this season. He just tossed his best start of the year -- 6 2/3 scoreless vs. Washington.
In his last start, Heaney went eight innings against the Athletics, notching eight strikeouts and allowing just three hits in a no-decision. He has pitched against the Blue Jays just once in 2015, when he allowed eight runs in 3 1/3 innings.
