What happened: The move drew little fanfare at the time. Bautista needed a few days for his first Toronto hit and roughly a year to move beyond a platoon role.
Why it matters: Bautista became a franchise-defining player and gave Toronto a new identity. Diaz played just 44 major-league games, underscoring how decisively the exchange tilted toward the Blue Jays.
By the numbers: Bautista compiled 37.0 WAR as a Blue Jay and ranks first among Toronto position players with 38.4 career bWAR.
What to watch: Toronto's scheduled game begins at 0-0 with the Blue Jays leading the series 2-1.
