He batted second and went 1-for-5 with a single and a strikeout. He also started one double play.
"Offensively things didn't go as much as I wanted to," said Hechavarria through a teammate translator, "I felt good about my glove today and was able to make some good plays. I felt good about it."
As for his first pro hit in the bottom of the eighth, Hechavarria said, "An infield hit -- I will take it for my first hit in professional baseball. I feel good about my first game."
The 21-year-old Cuban shortstop was signed officially by the Blue Jays on April 13 to a four-year, $10-million Major League contract.
Dunedin was playing the Clearwater Threshers, a Philadelphia Phillies affiliate.
Blue Jays second baseman Aaron Hill had a chance to work with Hechavarria last month when he was in Dunedin rehabilitating from a hamstring injury that put him on the disabled list.
"He has all the tools in the world," Hill said before Friday's game against the Texas Rangers. "When you look across the board, the five tools, he has all of them.
"Just a raw, good baseball player. I think with the right direction, the right coaching, just as far as learning how to get better at each stage, and learning from his mistakes and keeping positive throughout the system, he'll be something special, just from what he looks like. He's a nice kid, they said he's great. We took ground balls, hit together."
