Getting a rare chance to bat, Stroman smashed only the second homer ever by a Toronto pitcher as the Blue Jays bounced back from three straight losses to the Braves for a 9-0 victory over Atlanta.
Stroman (4-2) improved to 6-2 in interleague play by working 5 2/3 innings in which he struck out six, walked one and gave up seven hits.
Stroman, who had a pinch-hit double in extra innings at St. Louis in April, hit his homer to right-center field in the third inning and was all smiles circling the bases.
Mark Hendrickson hit the only other homer by a Blue Jays pitcher, connecting in 2003 at Montreal against the Expos.
Toronto's Kendrys Morales was 4-for-5 with two RBIs and two runs.
The Braves got bad news early in the day when it was confirmed that slugger Freddie Freeman fractured his left wrist the previous night when hit by a pitch, and nothing happened in this game to brighten their spirits.
Julio Teheran (3-4) gave up back-to-back homers to Luke Maile and Stroman to start the fourth inning and was pulled a walk later as his home struggles continued in a big way.
Teheran has surrendered 26 runs over 18 innings in his four straight home losses, giving up 30 hits and nine homers. He is 2-0 with a 0.71 ERA in four road starts and 1-4 with a 10.50 ERA in five home outings.
Darrell Ceciliani, taking the place of suspended center fielder Kevin Pillar, had an RBI double in Toronto's three-run first and a two-run homer in the three-run third. However, Ceciliano had to leave the game when he hurt his left shoulder on the home run.
Jose Bautista was hit on the leg by Teheran in the first inning in apparent retaliation for his bat flip the previous night, but he trotted to first base without reaction and scored the Blue Jays' first run.
