Didn't take him long to fit in.
The second pitch Donaldson ever saw as a leadoff hitter -- a 95-mph fastball from Carlos Carrasco -- was deposited onto the Home Run Porch at Progressive Field.
The following inning, Indians leadoff hitter Jason Kipnis also slugged a homer, making it the first time since May 14, 2014 that two teams had their leadoff hitters go deep in the same game.
"Yeah, I haven't seen that too often with leadoff guys hitting homers to start the game," Blue Jays manager John Gibbons said. "I'm sure it's happened, but I don't know if I've ever seen it. If you're a good hitter, you can hit anywhere."
And he didn't stop there. Donaldson singled, and later scored, in the third inning, staying aggressive by taking a first pitch slider up the middle. He walked in the fifth. He walked again in the seventh. In all, Donaldson went 2-for-3 in his leadoff debut with a homer, two walks, two runs and an RBI in the Blue Jays' 9-4 loss.
He doesn't expect to stick in the leadoff spot once Travis returns from injury, but his debut there, from an individual perspective, couldn't have gone much better.
