Toronto's lone run came in the bottom of the fourth. Second baseman Kelly Johnson led off the inning with a double to left-center field and later came around to score on an RBI single by designated hitter Edwin Encarnacion.
Blue Jays righty Brandon Morrow was nearly perfect against Pittsburgh while mixing in an overpowering fastball with strong command of his offspeed pitches. His lone blemishes were a pair of singles off the bat of Pirates right fielder Jose Tabata.
The 27-year-old Morrow struck out four batters without issuing a walk and throwing 34 of his 50 pitches for strikes. He finished the Grapefruit League season having surrendered just one earned run in 17 1/3 official innings. Morrow is expected to start Game 2 of Toronto's season on Saturday afternoon in Cleveland.
