In honesty, I'm more PO'd the Jays gave up Syndergaard than d'Arnaud. The guy is humble, and has a great work ethic. Plus, he has a plus fastball, an underrated changeup with good movement, and the game I saw him, he showed glimpses of a promising slider. Not to mention he's got impressive command for a strikeout pitcher. People on the Jays board know he's my favourite prospect by far (Of course he's my avatar).
Here are the highlights I took from the game I saw him pitch.
