Adam Lind and Lyle Overbay hit solo home runs and host Toronto gave Kansas City ace Zack Greinke a rare pounding with last night's 9-3 win.
Rod Barajas added a two-run shot for the Blue Jays, who boosted Greinke's ERA from 1.10 to 1.55.
Seeking to join Toronto's Roy Halladay as the only nine-game winners in baseball, Greinke (8-2) was instead tagged for a season-high seven runs - five earned - and nine hits in five innings. He walked one and struck out three. The righthander dropped to 1-4 with a 7.07 ERA in his career at Rogers Centre.
Overbay extended his hitting streak to 11 games when he lined a one-out drive to center in the second, snapping Greinke's streak of 111 innings without allowing a home run. The last player to homer off Greinke was Oakland's Daric Barton on Sept. 2.
Greinke allowed four runs - three earned - in a 7-4 loss to the Chicago White Sox on Sunday and has won just one of his past four starts after winning seven of his first eight.
The Blue Jays jumped on Greinke early. Marco Scutaro doubled and scored on a two-out single by Vernon Wells in the first, Overbay homered in the second and the Blue Jays piled on with a four-run third.
Alex Rios hit an RBI double and later scored on Tony Pena's throwing error, with Overbay capping the rally with a two-run double off the base of the wall in right. Lind made it 7-0 with a one-out homer to left in the fifth.
